Mazda 3 diesel

el_loco_blanco

Hi there,

My Mazda 3 is going wrong. Before Xmas I brought it to the garage because it was shuddering when I went above 100KM. There was also black smoke coming from the exhaust when I excelerated. No light came on at any stage! Apparently the filter was blocked and the oil was really thick. I got it back on Monday with a new turbo and a new cam shaft sensor fitted. The garage did full diagnostics and it got the all clear.

Today again the same thing happened on my way to work. The whole car basically shuddered or shook as I drove along. I particularly noticed it when the car was going up a hill. On my way home then tonight it was even worse. The engine light eventually came on.

Has anyone any idea what could be wrong? I don't want to go to the garage again in the morning for them to suggest another expensive part that doesn't need changing!

The car is an 07 but has 130K km on the odometer.

Cheers

Ah the Mazda diesel. Is it still in warranty? If not, bend over and grab your ankles.

Unfortunately not. It is 30K out of warranty which is about 15 wweks driving for me! Are mazda diesels notorious for problems? Anything I can yell at a garage about?

Notorious is the right word. My advice? Sell it before it melts your credit card. That said it's a bit soon for it to be chugging after a turbo replacement. Yelling at the garage might help, but don't mention the notoriety aspect. If that doesn't work, contact Mazda.

Basically, unburned diesel is recirculated back into the oil sump. The oil level gradually rises beyond the MAX level and the engine starts to inhale it, causing turbo failure and massive engine damage from oil sludge.

You're referring to the Mazda 2.0 diesel engine - I'm guessing that the OP has the 1.6 PSA unit which doesn't have the same DPF related problems....

The garage I am attending is a mazda dealership. Is this something that was my fault or would the dealership be expecting a query about this? It is a 1.6 by the way!

This engine as 245 said is a psa based engine.
Did the garage just change the turbo....as with peugeot (same engine)
they oil feed pipes are normally replaced,flush out the engine with engine flush as with the old turbo breaking up can cause small metal parts getting into the new turbo feed lines......:eek:
So unless they fit it correctly and carry out all that they should do you'll be fitting turbos for the next few years....have you had the dpf replaced....??

I think you're jumping the gun here, that's a PSA group engine, also in cars such as the boards loved Focus!
OP, I'd start with looking in the direction of the EGR valve.

el_loco_blanco

They replaced a filter which is probably the oil filter rather than the dpf. I will also ask if all the tubing has been changed. Thanks for all the advice.

Take Row's advice!

He knows these engines inside-out!

(Helped me with my engine which is the same as yours!)

Thanks mullingar ...but if i knew all the answers i would'nt be here
typing on a keyboard.....:)

These are a good Engine ...but require on the button services using the correct oil.
I use mobil 1 5w 30 esp ... http://www.mobil.co.uk/uk-english/lcw/products_services/mobil_1_esp.asp

This oil reduces ash build up with in the dpf which inturn prolongs the life
of the dpf...also its suitable for the dv6 turbo as the oil feed pipes can block
if the incorrect oil is used or if the oil change is pushed out...:eek:

Alot of other oil manufactures should also have the same spec as mobil 1

el_loco_blanco...
If they replaced the dpf you would know about it as the work out €400 just for the filter....:rolleyes:

Well then they didn't. It was 900 for turbo, 100 for sensor and I paid 200 for service just before Christmas.

OP - arm yourself with this information and get your recipts and back to the dealer with your good self.
Looks like they did a half job. Unfortunately you will have to fork out for the dpf alright, but because they didn't do the job correctly, you might get away with labour costs.....just guessing here......
Good luck.

Explain yourself a little better quacker and your reason for saying what you did? I am not that easily frightened. At this stage I am trying to ascertain if it is worth paying out for anymore repairs or just trade it in and get a new car.

el_loco_blanco....if the dpf was'nt replaced then i'd say its due with the mileage you've covered....some people remove and power wash dpf's
which is a help...:)
If your dpf blocks it puts back pressure on your engine and turbo which
could be another reason why it has blown the turbo.
You need someone with good diagnostic equipment like mazdas or
equivalent to check how the dpf looks on live data...this will indicate if your filter is getting blocked.
Your dpf should regenerate every 500 kilometers or so which cleans it but if it not regenerating it will block your filter very quickly...:eek:
I'd get it to the garage that put in the turbo in and ask them...

1)Did they replace the turbo oil feed/return pipes and flush out the system
while replaceing the turbo....also removing the sump and checking the oil pump suction pipe/filter for restriction is a good idea..:)

2)Did they check the dpf differential pressure and filter load with there
daignostic equipment....to check the state of the filter...??

If the turbo has failed again they should cover another turbo for you...but
they need to find out whats causing the turbos to fail before fitting another new one...;)
Best of luck with it....:)

...all of this just goes to prove: none of the current crop of (too?) high tech diesels is ever going to be a viable long-term car. If nothing else, the looney prices of the likes of the dpf means at some stage a service will cost more than the car is worth. Cue: new car.

So much for being 'green', then......:rolleyes:

Think you hit the nail in the head... galwaytt
A smaller hole in the O-zone layer But a bigger hole in our pockets...:rolleyes::):)

90% of the problems on modern diesels today are due to emission controls
that were added to them....:rolleyes:.....e.g. Egr valves.....Dpfs and i'll
add dmf's..
Never mind the electrical problems there also having...:eek:

I am new to the forum. However I have taken some interest in the problems of the Mazda 3 1.6 diesel. You might be interested in the link below.

There must be problems in the other makes that use that engine too then.
I think petrol is the way to go these days.
Is there any diesel engine out there that doesn't give problems? We've been hearing about problems with PSA diesels, Ford diesels, Mazda diesels, BMW diesels, VW diesels... not a lot left... Fiat diesels seem OK unless they're fitted to an Opel...

pburns

I think there's a bit of panic-mongering by some posters here. I'm not saying modern diesels don't have issues, in fact it's pretty clear major problems are commonplace at high mileage across many diffeent makes. However the PSA 1.6 is far from the worst and the situation isn't helped by ill-informed posters comparing the 3 diesel to the COMPLETELY different 2.0 engine that is known to be troublesome from the 6.

bazz26

I'm on my second car with the 1.6 PSA unit, the Focus had around 70k miles on it and my current S40 has close to 80k miles. Both serviced regularly with no issues to date.

el_loco_blanco

Thanks for those links ukzmisr. The recalls were from 2004 and my car is an 07. Just to update you all. Basically it is my work car so they decided to fit it with a 2nd hand engine as it seemed to be continually costing money to fix. That was 6 weeks ago and I have been back to the garage at least once a week since with minor problems!

Hi there,

A bit unrelated, but I had a VW Golf GT TDI with problems, and the thing cost me an arm and a leg to fix...I ended up forking out for 3300 euro for 3 new injectors and replacement camshafts because they were worn apparently...the car only had about 90k miles on it and was a 02. I don't think I will ever go near a diesel again. I currently have the 1.6 petrol Mazda3, and was kind of regretting not going for the diesel....not now I'm not!

dubmark74

Hi, i have a 2007 Mazda 3 1.6 diesel TS2. I just recently got the 75k miles service done, not with a main dealer though. He did all the usual but didn't do anything with the DPF. Looking at the manual it recommends replacing the DPF and topping up the fuel additive (adblue). Having a read around it looks like replacing the DPF is not necessary but topping up the additive should be done. Question is, does anyone know where the tank is for this and is it easy to top up. Thanks.
