Mazda 6 - Newest Mazda6 2.2D - DPF issues sorted??? - roscoman
Hello All,

I'm aware of the DPF issues the 2.0D Mazda6 (08 onwards) suffers from.
However, does the newer 2.2D engine have the same complaint?
Anything else to be aware of, or is the latest incarnation now a well sorted car?

As always, i appreciate your opinions.
Thanks

I'd also like to know about this - any experiences of this new 2.2 diesel guys?
Joe.

The question i'd be asking myself is...do i trust a maker or its dealers to do the right thing IF a new model had similar issues?

A makers previous behaviour when things go wrong is always worth researching before parting with hard earned.

As the owner of a 2009 2.2 Diesel Mazda 6, I have to say that in my experience these cars are a world of trouble. My car has spent more time at the dealers and I've spent more time having to sort out problems with it, and I've called the AA out more times - than the sum total of all my previous cars over my 20 year driving career (including some real bangers in my younger days!)

The Mazda 2.2 engine is affected by DPF issues - though it's certainly better than the previous 2.0, which many owners feel was simply unfit for purpose. The DPF seems to go into self regenerate mode an awful lot, which injects extra fuel to raise the temp in the filter. It does this even if you're on a fast motorway journey. The only sign it's doing it, is if you watch the instant economy on the fuel computer info display - every 20 miles or so it will drop from (say) 50mpg to 20 mpg for a good 5 minutes - even if you're on cruise control at a steady speed. It's quite infuriating because the amount of fuel wasted is astonishing and brings the overall economy down to Petrol engine levels!!

But it has far more significant issues than the DPF. The timing chain stretched at 30,000 miles and required replacement. It was off the road for over 2 months because the parts were on back order. According to the dealer it's a very common fault - not a case of "IF" but "WHEN".... to the extent that a recall was issued to check the chain tension - and it's now also checked at every service - and if it's deemed to have stretched beyond tolerance, you're prevented from driving the car again until fixed. If you insist, they make you sign a disclaimer which basically voids your warranty because you are going against their advice. So you're caught between a rock and a hard place.

When I finally got it back it spewed filthy black engine oil out from the timing cover - causing extensive damage to my driveway. Mazda's response? Complete and utter disinterest and flat refusal to pay for the damage it had caused. Not even an apology.

Mine is now approaching 50,000 and makes a rattling noise at tickover which I suspect means the timing chain is stretched again and will need another replacement soon. I'm dreading that - in fact I will probably cut my losses and get rid rather than go through that hell again.

It's been off the road on two other occasions due to parts failing.

From day one, Mazda have treated me as an inconvenience to them and seem to imply they are doing me a huge favour by repairing failed parts under warranty. After several years driving VAG cars, I am staggered at the attitude from Mazda.

On the plus side, the 2.2 engine has good performance (it's the 160-something hp version I have) and it's more refined than VAG TDI engines. But reliability, economy and poor customer service from Mazda mean I can't wait to get rid of this car & will never touch a Mazda again in my life.

I can't wait to get rid of this car & will never touch a Mazda again in my life.

Which is a shame - as the owner of a petrol Mazda 6 I couldn't be happier (although I've never used Mazda's customer service etc and mine's a used car). Nothing has gone wrong with it.

I only know of one other person with this car. an 09 plate 163bhp (same tuning as yours) and he's had no problems (besides the timing chain). He has a 15mile commute to work and he says the DPF regenerates around once a week - but still manages 45-50mpg to a full tank (brim to brim)

The chain was a recall or TSB - can't remember which one - my mate had his changed automatically when it went in for it's first service (he had no probs/symptoms). The new chain is apparantly different and shouldnt have the same problem.

Can I ask which other two parts failed?

Mazda 6 - Newest Mazda6 2.2D - DPF issues sorted??? - Roberts12345
I have heard instances of chains which have already been replaced, failing (stretching) a second time. Also know of an '11' plate 2.2 that's had chain replaced - so the problem still exists. I suspect the tactic is to defer subsequent failures in the hope that warranty expires before a 2nd replacement is needed.

Other faults which took the car off the road for several days were the brake master cylinder failed causing brake pedal to drop to the floor (!) & DMF (which Mazda didn't want to address despite a clutch judder so bad it caused the exhaust to bang against the chassis each time you pulled away from a standstill!).

Also air con compressor has leaked and the PAS pump intermittently stopped working.

I think it's because their new 'skyactive' technology is coming out soon - and perhaps in 2012 we'll see the new mazda 6. They must just not have bothered to fix the current problems as the engine is to be made redundant soon anyway, who knows.

Quite a few problems there! hmm, I think i'll stay clear of the 2nd generation until I see some more feedback.

Although I'm very happy with my petrol mazda 6 (1st gen) I cant help but perhaps consider honda for my next car instead. I'm hoping mazda can turn it around with their 'skyactive' tech coming soon as a mazda will always be better to drive than an accord

Thankyou for your feedback

It is a shame that Mazda has fallen from grace with the 6 diesel and to some versions of the 3. I had a 323TD that never missed a beat from new to selling it on after 6 years and 130k on the clock.. Is the Mazda CR diesel sourced from Renault?

Hi All,

Have just bought mazda6 2.0 SL 58Reg from Cargaint on new year eve. On the same night while driving i got an engine light i returned next day i was told by car gaint workshop that some nonsense mechanic has put more oil in the car tahts y oil level where at X mark. they fixed it but again after next day driving going to office on first day the check engine light came back on. i returned car again.

Since then the car is with the car giant. i have been in such a pain from the moment i biught this car. I wonder if it happens to all or is it just i being unlucky.

Cargiant is changing story every now n then so far they told me they are waiting for air flow meter air filter and air box which have been ordered form heaven and hasnt arrived as yet.

I have no clue what to do except just to wait listen to lame excuses from car gaint everyday.

I'd politely ask for a refund, looks like goods are not fit for purpose.

"On the plus side, the 2.2 engine has good performance (it's the 160-something hp version I have) and it's more refined than VAG TDI engines."

The good news is that the new common-rail VAG diesels are much more refined than the PDs. They also have fewer DPF issues, as I think the equipment has a bigger capacity. So yes, cut your losses and go back to a VW or a Skoda.

In answer to the original question I'd say the issue has not been resolved. There are still major DPF issues with this car but if it's not quickly resolved, it can lead to other problems such as:

  • DPF Blockage (Loss Of Power, Warning Lights On Dash, Limp Mode)
  • Stuck In Regen Mode (Dumps Diesel In Oil + Reduces Oil Lubrication)
  • Blocks EGR valve (Carbon Backup)
  • Backpressure Destroys Turbo (Carbon Backup)
  • Carbon Backup Damages Injectors
  • Carbon Backup Damages Engine Seals & can cause overpressurising

It's best to just get the DPF system completely removed from a competant specialist company such as s i n s p e e d seeing as they were the first company to ever bring out a solution for Mazda's and I believe they're still going strong as UK's most recommended - even by some dealers now..

Call me a cynic but this looks very fishy;

Perhaps next time, contact HJ to advertise?

I am interested in the Mazda diesel debacle, as an example of how something can be unfit for purpose and the problem ignored by the maker!

If I am reading this correctly we have a car here which needs its timing chain changed more frequently than a cam belt. Chains can transmit 200 bhp to the back wheel of a motor bike, admittedly only for a 100 mile race but how can't a chain, running in a bath of oil drive a camshaft for ever?

Bearing in mind the association between Ford and Mazda is there any commonality between their diesel engines? We don't get these sort of complaints from Ford diesel owners SAFAIK

Mazda's 2.2 is Mazda's engine. The 1.6 and 1.4 diesels in the smaller Mazdas are Ford/PSA and have their own issues.

How does the MoT tester, test for functionality? I'm not condoning the practice, but I can't see a gutted DPF being detected at thge MoT.
