Mazda 6- is the 2.2d engine trouble?

[james6546]

Mods- feel free to move to technical if it fits in better there.

I'm probably looking to replace my 9-3 at some point as my wife seems to hate it! The main contender is a Mazda 2.2d 175 Sport Estate in that red.

I'm looking on BCA and virtually all of the cars that are on there have advisories for the engine smoking, e.g.



I had a CX-5 a few years ago with this engine and it seemed fine, although I only had it up to 50k miles. Do I need to avoid these engines?

This would sadly rule out Mazdas for me as I don't fancy their petrol engines after coming from the 2.8T V6 in my Saab.

The engine has a very bad reputation. Like all cars you get good and bad but the general consensus on here is to avoid and go with the petrol.

Is this the diesel where the car pumps diesel back into the sump after a failed regen?

I had a Mazda 5 diesel and at the first 12,500 mile service, the service advisor told me to be prepared to be shocked at the price as the valve clearances were mandated to be checked and adjusted, with the cam cover coming off and a new gasket. Total cost for that was around £560.

Then after it left the dealer network for servicing the DPF light would flash, because it needed to be reset by the dealer annually. The dealer who checked reset it and found the DPF was only 4% full.

I have a 2.2D 150PS and it's fine. It might be more susceptible to oil dilution depending on driving style but otherwise, mine is spot on. Never had an issue any bigger than a vacuum line failing to the turbo.

I used to have a 2.2D - 2010 registered Mazda 6. Sadly it was nothing but trouble, frequent limp mode and visits to the garage for forced regen. Eventually gave up on it and traded it in.

2 x 2.2D CX5s here, from new took both to 100k+ in 3 years.

One was fine, the other had to go in for engine strip and walnut blasting due to carbon build up at around 50k.

I have had a couple of 6s and currently a 2016 CX-5 with the 2.2. It’s a nice engine to drive but issues are reasonably common, the carbon issues mentioned previously that require walnut blasting affected both the 6s but to their credit Mazda UK did support the cost of the work (can’t remember if part or all but certainly didn’t cost me a great deal).
One of the 6s also had debris damage the turbo impeller meaning a new turbo (I went for a recon unit) which I believe is not uncommon.

For me they are nice cars which look decent and drive well , they have a good standard spec too so I have stuck with them as family wagons. In the two years we’ve had the CX-5 it’s been faultless (aside from a new SD card under warranty due to media system glitching).

[james6546]

Thanks for the replies all.

I might try and get one still in warranty, then if there are any issues I can get them sorted. I certainly won't get one from BCA in that case.

I did like my CX-5 and the engine was good for what it was.

I believe post-2016 diesel models are more reliable. I’d avoid older ones like the plague!

This happened to a friend of mine. Think his was on a 2014 plate.

As posted above if you go for a 2016 onwards they revised the engine & so far they seem to be more reliable.

I had something similar with a Toyota D4D. Dreadful engine, I'd urge anyone looking at Japanese motors of that era to get a petrol instead!!

There is a service light and oil quality light, if you don’t reset both it won’t regen gas it thinks the oil is old

The oil pump chain stretches and takes the turbo out as it’s the furthest away from the pump

The chains stretch too causing so called dpf problems.
