Mazda 6: What items are replaced during a service?

[AGAR]

Hi,

I bought a 2005 Mazda 6 2.0d (non-facelift) a few months ago, and it will soon be due its 7-year/87,500mile service. To keep costs down, I am planning to buy the parts myself and supply them to a local independant garage to do the work for me.

The problem I have is that the service book I have for the car does not detail what items need to be replaced during any services. At a guess I would say the following need to be replaced:

-air filter
-oil filter
-oil change
-cabin filter change
-fuel filter

Does anyone know if that is correct, or whether there are any other parts to change?

Thanks,

Agar

I hate to say this, but I'd feel guilty if I didn't:

Google "Mazda 6 diesel engine problems", read everything you can and then make a decision.

My advice from bitter experience (costing me over £7K) would be to get rid and get another car. Petrol Mazda 6s are fine, but the diesel has some serious design issues that Mazda deny all knowledge of. I would honestly get rid of it whilst it still works and it has a value. It's gutting having to scrap one because it's fked up.

Sorry, but like I said, I'd feel guilty if I didn't say anything.

Hi - thanks for your reply.

I'm aware of the problems relating to the diesel engines, but since my car was manufacturered prior to July 2005 it does not have a DPF (the common cause of most of the problems).

I appreciate you trying to help though - cheers!

Autodata says just oil filter and pollen filter.

Timing belt was due at 75k/72 months if you haven't had that done.

Previous service history should obviously be taken into account, brake fluid every 2 years, coolant every x years depending on type etc.

Do the Mazda6's suffer the same DMF issues as their sibling Mondeos ?

[AGAR]

Thanks Jimmy - thats a great help.

Mondeoman - I'm not aware of any DMF problems with the 6's - in fact I'm not even sure if mine has one?!

There is usually a service manual on the web, I think it's ok to post a link http://manuals.wibla.net/mazda/Mazda6/Workshop_Man...

Oil change, oil filter and Cabin air filter "aldehyde filter" (pollen filter is next service)

Thanks - thats exactly the sort of thing I was looking for. Quite strange that it's not covered in the service record book?!

I'm pretty sure they are the same thing although would be happy to stand corrected ?

The DPF isn't the root of the problems.

They start with under-specced injector seals (Mazda issued an uprated set for the 10K service on most cars) which blow soot up under the cam cover. This contaminates the oil and blocks the oil strainer. The oil strainer is situated at the front right of the engine which means that accelerating away from roundabouts can starve the engine of oil even if the oil level is within range on the dipstick.

That is just the start. The Mazda spec oil that is recommended for these cars is gash. It's a low ash oil because of the DPF but all cars are recommended the same oil. The DPF just exacerbates the situation by effectively diluting the oil with lovely diesel. :|

To the person above who asked if it is the same engine/DPFGDMF system as the mondeo, I believe it is.

It's quite telling that Mazda used a clean sheet design for the new diesel engine in the new Mazda 6. Although a reliable source tells me that these have major issues too with cam chains stretching.


My advice again: avoid Mazda 6 diesels.

It's such a shame that a well put together, good handling, nice looking car was let down by such basic errors that should have shown up in testing.

I think they were an option, same "pollen filter" but with active charcol and gets changed every service.
Not sure about this though.

Life Saab Itch, did you actually read the OP's post, or do you just make it your lifes work to bh about the Mazda6 at every opportunity because YOU had a problem?

The OP's car is a pre facelift - therefore no DPF ergo no low ash oil either

There may be problems with the diesel engine, but not the extent that you make out.

As for the injector seals, yes they can be a problem, but a lot if the problem is caused by poor figment following removal of the injectors during service (the workshop manual specifies that the injector holes should be thoroughly cleaned, if they're not then the injector seals may not seal correctly) so it depends on how well the car has been serviced

Did you read Life Saab Itch's?

What's the harm in him offering his point of view as a previous owner? I feel inclined to offer tales of experience and woe with certain service centres and the Renault Megane II. To someone who may be searching for info on Google or what have you, seeing something like LSI's post might be of use, even if it isn't of interest to you and may not affect the OP. In my experience, any information is handy.

OP, if you know what's been done previosly to your car at services, maybe it'd be worth calling a Mazda dealer and telling them what's been done, it's age and milage etc and asking them what might need to be done. JonnyFive is usually up for offering information.

[JonnyFive]

That'll be me.

You've already had most of the information you need above, but anything else drop me a message.

[AGAR]

Thanks Jonny - I think the info posted above should be all that I need. But if I have any other queries I'll be in touch.

Cheers

Yes, I did read the OP.

What I posted was entirely relevant to this thread.

If you were to do the amount of research on the issue that I have, then you would find that although most of what you say is correct, there are bits I would strongly disagree with.

Try and read a few independent engineers reports on the failures rather than accept the official Mazda line.





For what it's worth, I don't go out of my way to slate the Mazda 6. It's a great car. I was directed to this thread because of my experiences. I wrote my views so that hopefully the OP won't end up with a £7K bill at the end of it and a dead car.

I've had 5 of them, all diesel, all of which have covered around 100k before changing them for a new one. Not one of them ever had a failure of any kind

They were always dealer serviced, and all I ever had replaced were tyres and brake pads/discs

I too was aware of the 'issues' with the diesel, but like I said, never suffered any problems

I'm now on my second Mazda3 with a 2.2 diesel, and as yet, no problems with any of those either

Then you were lucky.

There is enough evidence/reports on honestjohn for it to be a big issue. It genuinely isn't just me.

The Mazda 3 has a different engine apparently.

It's good to hear some positive feedback about them. Until the engine went in mine, I had no issues with it at all.

One other point, buying the parts and then getting a garage to fit them may not save you any money.

And any problems down the line resulting from the service are going to be blamed on the parts you
provided.
