Mazda 6 - diesel engine problems

    Hi All,

    Just wondering how many people have suffered problems with their Mazda 6 diesel engines?

    My reason for asking is that mine, a 2006 with 68k on the clock, developed a serious knock on the way to work on Monday. The dealer tells me they rarely go wrong, but searching on Google tells a different story.

    Does anyone else have experience of these going wrong?

    ...if it's a knock, it's down to two things:

    1. DMF - it's a consumable part, so suck it up ! OEM part is Eur1100 iirc, whilst a LuK replacement kit is less than half that. That's if you're lucky.......

    2. More likely, though, is the fact that it's big end no 4 on the crank that's gone. That's if you're unlucky. And it's going to cost you. New short block from Mazda Irl is Eur 2800 + VAT (less than the cost of the sum of it's parts......)

    .......and you'll need a new DMF to go with it, as well, and the labour to fit, all.

    Going to be an expensive day out, either way - but do post up on the verdict, sorry for your troubles.....

    Realistically, I've had to scrap my 02 car with 88k miles on it. Not a good experience.....

    ...my SO has just spotted this now, and nearly spat her tea over the computer.

    She's right - first thing; DON'T drive the car !!

    Mazda 6 Diesel is a wreck waiting to happen, if you believe the reports.

    Good news and bad news on the car front...

    Good news, my 13 year old Corolla, that I was trying to get rid of, just passed its NCT, which is great because..

    Bad news, the engine in the 6 is shagged. Big end bearing gone, and more than likely all the associated issues.

    Gutted to say the least!!

    Did you get a number, for cost-of-repair ?

    ...if you could, could you confirm that it's #4 big-end.

    I think we now have the bones of Mazda diesel bonfire here ! You can even put your 6, on top ! :o

    fwiw, just goes to show that a 'fsh' isn't necessarily the be-all and end-all, of anything.

    I have a tentative offer for my rolling Mazda shell, and rooting out the book to get the VIN, I see the service book. Serviced according to the book at:
    9148, 18758, 27218, 39661, 49523, 58890 (incl timing belt), 67759 etc..........fat load of good all that did.......

    fwiw - got a quote today by email for a re-con engine for Eur 2240. So, add in removal/refitting, DMF, clutch, etc etc........and..........I'm edging closer to the crusher...........which is a pity - it's a fine car. Sorry, chicken coop.

    Hi All,

    Just an update, got the 6 back, final cost was just shy of 4k!!!

    2900 for the engine rebuild, I don't have the invoice to hand so cant be more specific (when I find it Ill update)

    1000 for the labour, (including a service after 2500 miles and both figures include VAT)

    Now she is running perfectly again and is still a lovely car to drive, I just have to decide what to do with her :confused:

    Ouch, €4k repair on a 06 Mazda 6 diesel works out at over 1/3 of the market value of the car. I'd keep it now until it dies as you will never get that money back. Trading up will cost you more money.

    ...now I know it isn't just me. Good candidate for a sticky, the tale is so bad.

    Fwiw, I couldn't fix my diesel, and flogged it on DoneDeal. 02, 85k miles, lovely car...........for Eur 750. That's a 5-figure loss inside 18 months.

    Cheaper to drive a 911, tbh............

    Friend had their 2.0D go recently too - shortly out of warranty 2006 model. New engine €10k (covered by Mazda), labour €2k (paid by them).

    ...the only certainty I'd say is, any Mazda with the RF series, common-rail turbo diesel, is to be avoided at all costs.

    Older, pre-common rail stuff should - I say should -be o.k.

    Is the latest 2.2D in the 6 a development of this do you know?

    I had a petrol 6 (1.8) and whilst it wasn't the smoothest or quiestest engine in the world, they have a reputation for being unburstable. The rest of the cars are well put together too. Such a pity the 2.0D was such cack...

    I know it would be slightly retrograde step but could you replace a bust 2.0d with the petrol engine? I'd be considering that if stung so badly...

    I had a 6 for a couple of days, it was the 1.8 and it was really nice, I'm shocked at these prices for replacement engines, sounds a bit OTT.

    ..wouldn't be worth the petrol engine conversion - you'd buy an entire petrol car for less than the work involved.....petrol tank, pumps, ECU, wiring loom, clutch, gearbox, the list would go on and on. By all means buy a can of petrol.........and use it to torch the car........

    I had gearbox cables fitted to the MPV before the engine went, and that cost 750, so that sort of price scale is not unusual for Mazda's, it would appear. As for engine price, I did up the prices before I scrapped mine, and a new long block was just under 5k iirc. I'd say the 10k mentioned above was a turn-key unit c/w turbo, ancillaries, injection pump, vacuum pump, flywheel and clutch (over 1100 alone)etc. Iirc, a cylinder head on it's own was 2k+..........crankshaft w/o bearings, 1800. Add labour to build it, and it won't be long getting out of hand.

    As for buying anything common rail diesel - 2.2 or no, I would have zero faith in it. Unless they're going to give you an KIA-like unlimited 7-year warranty on it, and the car at half price, I wouldn't touch it with a barge pole.

    Well just found this thread so had to add to tale of woe.

    I have a Mazda 6 03 diesel with 102,000 on the clock.
    Was driving fine.
    Few weeks ago driving back from West to Dublin began to notice a bit smoky when I accelerated.
    Thought nothing much since had diesels that were smoky before and I would just check it out when got home.
    Then accelerating away from toll plaza on M4 boom bang
    Engine started knocking badly, all sorts fo noises, would not shut down.
    I and the motorway were covered in smoke.
    Left trail of black on the road as I veered into hard shoulder.
    Guys in toll plaza thought I was on fire.

    Anyway firstly thought it was blown turbo that sucked oil into engine but now according to mechanic turbo not totally blown and still fair amount of oilleft in sump.
    He needs to check how bad engine is, but it does not sound hopeful.
    I have been quoted 2,900 for engine import with 3 month guarantee.
    Not even reconditioned engine but just second hand.

    Anyone ever heard of similar story ?
