Problem with engine re-build on Subaru legacy

    Recently I had the misfortune of engine failure on my Legacy diesel, I got it rebuilt by a Subaru dealer which included,
    New short motor,
    Reconditioned injectors,
    Reconditioned cylinder heads,
    New clutch,
    New dual mass fly wheel,

    The problem is, after a long drive 40 min or more, when the car is turned off it wont start again, it takes on average of 7 turns of the key, after each turn the conk out has a serious vibrate.

    The car has been back to the dealer twice, they say they cant find any fault, haven't a clue what it is, nothing is showing on the diagnostics, so they cant fix it. I drove it for an hour and called to the garage and gave them the key, it didn't start, so they have seen the problem and acknowledge it's there.

    It's an everyday occurrence, as home-work-home is an hour drive each way, It's getting bloody annoying now, as it's been going on for almost 2 months now.

    The guess' I'm getting off people are, sensors, injectors, or the fly wheel, would a problem with these show on a diagnostics scan??
    If they cant fix it, should/would I be entitled to a partial refund, I'd prefer it fixed though as not knowing what it is, how much it would cost to fix?

    Anyone ever have such a problem or hear of same?

    Before I give my opinion, does the car struggle to start when its fully up to temp? I.e. Works perfectly when the engine is cold but once its up to temp the issue starts?
    Forget the flywheel theory as this wont stop a car starting..

    It could...

    Yes, starts no problem first thing in the morning, short trips, drive for 30min re starts first time, just after the long drive, turn it off, wont start, leave for 5-10min still doesn't start first time,

    Crank sensor?


  • Registered Users, Registered Users 2 Posts: 7,934 ✭✭✭Renegade Mechanic


    If the crank pickup was done at the flywheel, then damage to a flywheel tooth could indeed cause this, though as you say, it's when the car is warm. Now, the engine has been completely disassembled and reassembled, so there are an awful lot of causes, and the garage knows this....

    However, let's pretend it wasn't. Typically speaking the faults that cause hard starting when warm are as follows.

    1: Coolant temp sensor. They tend to start sending wrong signals, but not signals bad enough to trigger an EML, before going altogether.

    2: The temp sensor section of the MAF sensor in the air intake. Again, similar to the coolant sensor, signals can be off without triggering an EML (Thinking the air is -6 when it's 10 degrees, for example).

    3: Crank sensor. These can sometimes wear out, in any vehicle, and lose what's left of their magnetism when the engine heats up, making starting when warm extremely difficult. It may have been damaged during the job, or simply ageing and is now going, simply out of Murphy's Law..

    They're the more common causes and require monitoring of sensor parameters, rather than simple "read fault codes" options on diagnostic machines.

    In your case, it could be anything :o
    You're going to have to put the foot down, and they're going to have to get stuck in. It could be as simple as a forgotten vacuum/boost pipe!

    Re Crank sensor.

    I haven't touched or messed with this engine, thought i'd leave this to the experts, and they haven't a clue, (they say) would that show up on a diagnostics, they say nothing has shown.


  • Registered Users, Registered Users 2 Posts: 5,572 ✭✭✭Colser


    What exactly is the dealer saying about this problem selous and how the hell are you keeping it civil when dealing with them at this stage?

    Oh they're suggesting it's the ignition switch, suggesting things that has nothing to do with the stuff they done, but they say they haven't a clue, they're seriously fobbing me off I feel.

    Depends on the diagnosis. If they spent over an hour looking at all the parameters - while knowing what they should be - and checking that, then they could find something.

    If they simply hit "scan for faults", then they wouldn't see much..

    But that's not to say they haven't gone through the engine bay with a fine toothed comb. I can only imagine how frustrating that is. And I know first hand how frustrating it is when a fault develops in a car while you're working on it,you have no idea of the cause and you just can't pin it down :o


    But, at the end of the day, it's on their hands, so they have to take it on the chin and find out. Give you a car if necessary.

    So you bought the car new from them,got it serviced on time and always with them,paid huge money when it packed up to get it back on the road and now when its giving trouble as soon as you get it back theyre fobbing you off...honestly Id drive it in to them and demand a car from them until its sorted.

    Something suggests to me it could be the crankshaft sensor.
    When it fails you can start and drive no problem until it gets hot and wont start until It has cooled down.
    Re the flywheel, do you mean where its connected via the starter?
    Just seems strange it would happen.
    What about the fuel pump?


  • Registered Users, Registered Users 2 Posts: 12,866 ✭✭✭✭bear1


    Just noticed you said recon'd injectors.
    I wonder if they coded them correctly as this would cause a world of issues if they weren't.
    Id want to see evidence that they were indeed reconditioned by a reputable company, I believe they are Bosch injectors.
    It might be worthwhile getting an injector test done too.
    You could be looking at a fuel issue, was a full service done as well? New fuel filter for example.
    Is the car down on power? Smoking?


  • Registered Users, Registered Users 2 Posts: 1,432 ✭✭✭Damokc


    Crank sensors. I've a Vectra and it struggles to start sometimes. 7 times out of 10 it will not start first time. But like Sex Panther, it starts second time, every time. I've been told its crank sensors that need to line up as it were, to tell the engine the its in time. If they're a fraction out it thinks the timing is off and wont start. I presume when it's turned off for a few seconds and you stop, they realign and it starts?

    A full service was done 2 months before the engine went, the injectors were done by the only Subaru approved place in Ireland (it seems), I think they're piazzo (?) injectors, they cost E1000 to recondition..

    Mine is only after a long (1 hour) drive, starts first time any other time, but not after the long drive, it's an average of 7 times before it starts, the shake it gives when it doesn't catch, seems to be getting worse too. it can be 20min or so before it starts first time after the long drive.


  • Registered Users, Registered Users 2 Posts: 12,866 ✭✭✭✭bear1


    Ok but when the engine was overhauled was the service re done?
    What caused the engine to fail btw?

    Yep, bought off them new, serviced off them every time, E6k to fix the busted engine with them,
    It was in with them for 3 days, I had a loan car for that time, "funny" thing is, they said they drove it to try and get to see the problem, (but I reset the trip computer when it went in), they didn't go too far, being as the guy, when I was there said he'd take it for a spin as he was going out then. I know where he went, and there was no mileage put on the car after his return journey,


  • Registered Users, Registered Users 2 Posts: 636 ✭✭✭canhefixit


    Get a crank sensor either from a breakers or if your local factors has generic they arent that expensive and they are an easy fit, worth a go and something else you can defo rule out either way

    If it dosent work change sensors back and sell your new one on ebay so your down nothing but have ruled one thing out

    A bit of messing yeah but sometimes its worth it just to get problem sorted

    Does it smoke on restart?

    They're Denso injectors btw

    Glow plugs, fuel pipes,
    It cost almost me E6k, (Subaru supplied the short motor and cylinder heads free)
    According to them, the diesel had no lubricating properties, messed up the injectors, created a blockage in a lubrication chamber, which in turn the con rod broke.

    Yes, Denso, (Ta)

    No, it doesn't smoke, when I have foot on the clutch, but if I keep key turned and foot on the accelerator it does, (when im P****d off with it)

    Another possibility is a faulty or badly earthed coolant temperature sensor. It won't necessarily show a fault on a scan as they are often designed to fail in a way that sends a default signal to the ECU so that the car will still run. Often the car will smoke on a hot start as it'll be running way too rich on startup. Unfortunately yours isn't showing that particular symptom but it'd still be one to investigate, especially on a newly installed engine.

    How does it drive once it runs? It'd expect incorrectly coded injectors to show way more problems that just a hot start issue.

    Has it kicked off any injector recalibrations since you got it back? Have they run to completion? (mine wouldn't unless the A/C was switched off as the compressor interfered with engine load)

    Denso may be the brand, but I believe piezo injectors is the information you were trying to convey. (Versus "traditional" solenoid type injectors). You weren't too far off with piazzo :-)

    Is this a common rail system? If it is, and it's anything like the Bosch system used in some of the Renault, Nissan and Opel range, then this could be a lack of rail pressure when cranking, the injectors then don't fire and it won't start, despite having been running until literally a few seconds earlier.

    To get some hints, if you can get access to an OBD reader, you need to use the live data option to check what the common rail pressure is when cranking, and then find out what pressure the injectors need to operate, and make sure that the cranking pressure is above the injector operate pressure. It should also tell you at the same time if it's correctly seeing the crank (or cam) sensor

    I'm being driven demented by an Opel Vivaro that has this issue, there is a lack of fuel rail pressure when cranking, so it won't start. If we use Easy start on it, it starts,and keeps going, but that's not a lot of help, in that if it stalls, it won't restart again, and the only way to get easy start into it easily is to remove the air filter from the body, which is not instant.

    Shore, if it was easy, everybody would be doin it.😁



  • Registered Users, Registered Users 2 Posts: 12,866 ✭✭✭✭bear1


    Which would point to the fuel injection pump? Pray op it isn't that.
    When it was suspected in my old 156 the mechanic quoted over 500e for a recon unit.

    Oh Gawwd. My sympathies OP you don't deserve this after buying a. new Subaru. I do hope you get sorted.

    I had a diesel Outback (used) marked as my next car. I just couldn't buy one now having researched the engine problems.

    I am back to looking at a 4wd version of a Mondeo / Volvo / Skoda etc.

    Funny that, I also was very very close to getting an 08 diesel legacy but 1) I couldn't find the spec I wanted and 2) I read about its horrendous injector issues.
    Which are made worse due to the fact that they aren't located at the top of the engine.


  • Registered Users, Registered Users 2 Posts: 1,373 ✭✭✭selous


    I got an email after I wrote a complaint to Subaru, they told me it was the diesel I was using here.....now if I was to forward said email to the company that I've being getting my diesel off for near 3 years now, wonder what they would say??

    I looked on internet after my engine went too, did I get a shock, everywhere in the world, they're breaking, strangely they seem to be around the same mileage here and U.K that they're going at too, 150,000km/100,000miles, the crankshaft seems to be main thing, and with a full Subaru service history they are repairing them free in U.K, I seen people who have had the problem Thanking their garage and Subaru for the repairs, It was my injectors that went so (apparently) due to the fuel I used, so it wasn't a manufacturing fault.. said the email.


  • Registered Users, Registered Users 2 Posts: 11,220 ✭✭✭✭Lex Luthor


    Just to add to this....

    I ran a Legacy 2009 model diesel since 2009. I noticed this happening in the last few yrs. No problem in the morning, no problem after a short run. But if I drove for a while (like OP says 1hr or more) and stopped and tried to start up again within 5-10 min, it wouldn't start.

    Used to drive me nuts...finally got a bit of a knack to getting it started again...but it used to be tricky at times

    Never got to the bottom of it as I just traded it in recently when I seen all the posts about this engine failure....my sympathies go out to you..

    They're a great car but these issues just soured my feeling towards them


  • Registered Users, Registered Users 2 Posts: 1,373 ✭✭✭selous


    Good to know it isn't unique.....or is it?

    I couldn't sell it private knowing it isn't right, because I wouldn't like it to happen to me, But this feels like the same thing, I paid for it to be fixed and it wasn't, now they cant because they don't know what is wrong, is this not where old school mechanics kick in, trial and error. I popped into a mechanic a friend recommended, he said the engine doesn't sound right at all, :eek:
    Think I may have to go to a different garage, cause this isn't doing my sanity any good.

    I wouldnt let anyone else near it at this stage selous ..I would definitely be going legal at this stage are they are totally messing you around again.

    Email Subaru Ireland links to the stories in the UK and ask them to justify why it cost you to get the same problem repaired here. Its obviously a known fault and they should have covered your repairs imo.


  • Registered Users, Registered Users 2 Posts: 1,373 ✭✭✭selous


    I'm going down to them on Thursday, then email Subaru, then I think it is time for a legal chat see what the right way to go is, it just stinks now.

    Any update on this saga?


  • Registered Users, Registered Users 2 Posts: 1,373 ✭✭✭selous


    The saga is continuing, they cant find whats wrong with it,
    Done full diagnostics when its cold, injector spray pattern etc, nothing.
    I warmed it up for them, drove it for 70min, they plugged straight onto diagnostics without turning it off, nothing showed, when they turned it off and restarted it, it started first time, so whether the idling for 20-30mins while diagnostics was been done does something,(cooled down) I don't know. it's been in 3 times now for a week at a time, I'm no better off they're no wiser, It's a niggle, but it wasn't there before the engine broke, and not what I want after paying what I paid for the fix.

    Next cause of action I would do is to data log constantly until the starting problem happens again. Then examine the sensor data to see which signal is missing or implausible when the car fails to start.

    Get a 10 quid bluetooth OBD-II dongle from ebay and use for example OBD Fusion app on android to log the data.

    Very sorry to hear about your issues OP.

    Subaru make great cars, with great petrol engines.... but the diesels are best to be avoided. I would suggest it may be better to trade your car in for something else... perhaps a Honda or Skoda, or a petrol Scooby.?

    Sometimes you might be better to just cut your losses rather than get into a legal argument. It might suit the garage too.... if they are so insistent that there is no issue with restarting the car, then they should have no trouble with taking it as a trade in against a different brand.

    I found this site here, describing different Subaru engines which I thought was most informative..

    http://www.subaru.com.au/subaru-dna/subaru-engine-range

    Specifically mentions the features of each engine, with the diesel not being suitable for short runs.

    Most interestingly.... the new petrol Engine....FB4... 2 litre, non turbo long stroke is giving good economy... .around 42 MPG (which in real world is about 37?). So you would probably be much better off staying with a petrol engine.

    With regard to the Crankshaft failures.... seems to be a common enough occurrence. It would appear Subaru are blaming lube oil starvation to the crank (caused by dirty fuel, sludgeing up the sump and starving the L.O. pump. However... if L.O. is not supplied to the engine, all sorts of problems occur, notably white metal bearing failures, scored cylinder liners, broken piston rings, camshaft damage etc. Any running surface will be damaged.

    But on checking the www / Your tube videos / various facebook pages of broken crankshafts, the crankshaft is breaking on a non running surface i.e. where two crankwebs meet.

    I do find this puzzling... why are Subaru blaming poor L.O. supply, when the part that is breaking... is not designed to be lubricated. i.e. it is a non running part of the crankshaft, that is to say crankwebs do not have running surfaces. Crankpins, and bearing journal surfaces require L.O. but not crankwebs.

    I'd buy a Subaru no probs.... but not diesel. Better off with a Dacia Duster or something.

    I do long journey, almost 90km each way home-work-home so not too short and knocking out 5.5-6L /100km (45+mpg) im happy with that.
    I had a service on mine 2 months/5k km before it broke, I bought the car because of the reputation the build had, was I left with egg on my face, in the 7yr I had it only a brake bulb went on it, then that.
    They don't have any car I like, But maybe they could source a car I do like and take it as a trade in, eh?

    I had a similar problem with a diesel golf, would start first time in the morning no matter what the temperature, but after an hour drive on a motorway it would take ages to start, turns out the starter had slowed down and the ecu wouldn't inject the diesel when it was hot as the engine wasn't turning over fast enough, got a new starter and that solved the problem.


  • Closed Accounts Posts: 8,585 ✭✭✭jca


    They aren't an engine I've ever even looked at but do they have a butterfly in the manifold that closes when the engine is stopping, an anti shudder device of sorts. Maybe this butterfly is sticking shut when the engine is hot preventing it from starting.

    Well... on the positive side.... in the 7 years (which is a long time to hold a car IMO) you have made a saving on your 180Km daily commute. In addition you have made a further saving on running a Subaru which are well known for reliability. Only having to replace a light bulb..... well you canna get better than that now can you?

    The Legacy is a lovely car. It sounds like your garage has tried to save you money in the rebuild. But unfortunately there is still an issue left. Subaru spare parts IMO are expensive, one of the downsides in owning a Subaru, certainly would never be as cheap as a Ford.

    On another point about Subaru Diesel Crankshaft failures, if it really was the case that it is a fuel quality issue...... then how come the other manufacturers of diesel engines are not suffering Crank failures as well?

    Mercedes, BMW, Skoda, Volkswagen..... no crankshaft failures in their diesels.... and they are burning the same fuel as the Subaru diesels.

    Interesting, this is only since the rebuild though, could be a coincidence, almost everything else is new,

    To be honest, I haven't a clue, this is one engine I haven't looked at to much at all, everything is well hidden, and not a thing I'm going messing with, tooo technical.

    Well... on the positive side.... in the 7 years (which is a long time to hold a car IMO) you have made a saving on your 180Km daily commute. In addition you have made a further saving on running a Subaru which are well known for reliability. Only having to replace a light bulb..... well you canna get better than that now can you?

    The Legacy is a lovely car. It sounds like your garage has tried to save you money in the rebuild. But unfortunately there is still an issue left. Subaru spare parts IMO are expensive, one of the downsides in owning a Subaru, certainly would never be as cheap as a Ford.

    On another point about Subaru Diesel Crankshaft failures, if it really was the case that it is a fuel quality issue...... then how come the other manufacturers of diesel engines are not suffering Crank failures as well?

    Mercedes, BMW, Skoda, Volkswagen..... no crankshaft failures in their diesels.... and they are burning the same fuel as the Subaru diesels.

    The downside was the 2-3 services a year, as you say, parts/services are pricey, the 60k-km one is a beaut, all transmission fluids etc are done, but it's the only time it seen a garage, that's why I got the rebuild, any other car I probably would have let go,
    I have asked that question too, why isn't every other car brand having the same trouble, as we all use the same diesel, some cars with 2-300,000 km on them and still firing away, It was Subarus first toe dip into the diesel market I suppose, but how tested was it, as mine isn't the only one to break down.

    6 months now since I brought the problem to attention of garage and Subaru Ireland, It still has the problem, but in that time they have
    Done full Hot/cold diagnostics
    Replaced crankshaft sensor
    Replaced the fly wheel
    Tried a different starting motor
    Replaced EGR valve, old one wasn't closing, but it made no difference to the problem, so it was changed back (foc)

    I'm now waiting for them to call as they're going to change the ignition switch, to see if that's it,
    The car will start if you keep the key turned longer than is normal, could it be the problem, but why only when it's at full temperature?

    They are trying, but 6 months.

    Go low-tech on it

    Get a good volt-meter and a oscilloscope and a pressure gauge for the fuel rail

    Connect one channel of the scope to one of the injectors and the other to the crankshaft sensor and see what it's doing

    when cranking cold ( when it starts first go)
    and cranking hot ( when it doesn't )


    Connect up the pressure gauge to the fuel rail and see what it's doing

    when cranking cold ( when it starts first go)
    and cranking hot ( when it doesn't )

    It's not something i'd be capable of doing, I wouldn't interfere with it at all,
    I was going to put a recording of it "not catching" here but too big a file, only pic's it seems,

    They said they'll ring me when they get the next part to try, (almost two weeks now)

    Just bought a beautiful legacy estate and two weeks in I heard a noise while on the m50 and then it came to a halt . I've been told its the crankshaft . The guy that sold it to me is after finding one in Lithuania for 1600Euro he's willing to give me 600 towards the rebuild Subaru won't look at it because no full service history . I feel like I've just thrown the 8000 Euro that I paid for the car out the window . Any suggestions would be appreciated anything that might help thank you

    If you only had it 2 weeks, Consumer rights should help you or the SIMI, I think that would be your best bet, any sold on car should last more than 2 weeks, dealer or private.
    Hope you get something sorted, these engines are not cheap to get or fix.

    Who told you it was the crankshaft?

    hi sorry for the late reply had trouble signing in. I asked the guy i bought the car from who owns a crash repairs place to sort it as we had a verbal 12 month garauntee agreement . he arranged to have the car collected and brought to a garage that he said has done some work for him before. I have tried to get in touch with him and find out the name of the garage so i can speak with them directly but it is not easy .
    the last time i spoke with him he told me he had sourced the parts and would need 1100 euro for them and that he was only willing to put 500 towards the repair costs. I figured this is still cheap considering the costs i have seen for this type of repair online.
    I am starting to get worried i am being played and plan to drive to mullingar tomorrow and visit the garage without his knowledge.
    I rang the guy who towed it there and he has giving me directions .
    Hopefully i am just being paranoid
