Hi all,
I wonder if anyone has any experience of this and can help please.
I have just got my CX-5 2.2l Skyactive Diesel back from the local garage after a decarbonisation was required. I'd been getting EM light and various other warnings. This usually occurred when going at mid-high revs on the motorway and easing off the throttle. After discussing with a relative who has the same car, he suggested carbonisation was the problem and (as a retired mechanic) had done the job to his himself. So I took it into my local garage (not a Mazda specialist) and they confirmed this was the problem, and have now cleared it out. The air intake manifold and EGR valve were both reduced in air flow by about 80%! The problem seems to be solved and no warnings.
Following completion of the work, they advised me that following having this work done, they have seen online that some vehicles were experiencing Turbo failures about a month after decarbonisation. This is thought to be due to a part of the turbo that was previously fitted with rivets and these failing and had resulted in the specific model of turbo being superseded. Apparently this was reported by Mazda in a Technical Service Bulletin (TSB). There wasn't a recall on these so i'm struggling to find anything. I contacted Mazda UK and they advised me to contact the local Mazda dealership. They can't see anything on their system, but have offered to do an inspection to look for damage (for £144). However, I'm not sure this will reveal anything specific, as if there had been any visual damage, the local garage would have presumably been able to tell.
Has anyone experienced this and have anything they could share?
Many thanks!
