Given I have the same answer from two trusted local garages, who have both seen in person, I think the conclusion is that neither are concerned and, it could be a number of things. I think the answer is to monitor, run some cleaners through the fuel and induction systems and run on premium diesel and just see if it clears up, remains the same or gets worse. If it gets worse then, I know it's something failing and it will need to go to a garage It may resolve itself, if oil was making its way from the leaking rocker cover gaskets onto the injectors. Now that supply of oil has stopped, it may just need time to burn everything off (and be hot enough to do that). I think the key is to do the obvious things first and monitor for a month or two. |

Having read your posts re smoke, I was out today so took the opportunity to see if there was any comparison. Took the car up to 3500 rpm and not a trace of smoke.

I'll run for 2 or 3 weeks, get some good motorway runs through it, fuel system cleaner, induction system clean / turbo clean and go from there.

In my opinion...excessive carbon build up in exhaust this is not based on the description. I mean, ok it may not have a DPF but it is still relatively modern turbo diesel technology.

You know what, I'm beginning to think it's a remap.

In the meantime, I have thoroughly checked both top intercooler hoses and they are both in good condition, properly sealed and don't seem to be more than 3 or 4 years old.

If you dont have any diag gear which you will more than likely have to have to get any idea of what is happening here id be doing the simple things you can easily do which may well be a cause like cleaning the air flow sensors and intake boost sesnors etc... easily done plenty of info on here about it

I think I may have an idea, as diagnostics showed no issues on the PCM after clearing old codes.

Nice one. Never saw issues like this on my 1981 Fiesta. There’s progress for you 🤣.
