Evening everyone,
Wondered if anyone had any thoughts on this.
I have a 2010 Mondeo, 2.0 TDCi 6 speed, which I've covered 10k in, over the last year. Fantastic car, rapid, 55mpg, handles well. Not had a single problem. 79,000 miles, lots of history, and home serviced by me including 3k oil and filter changes.
Tonight, I went to go to Argos to collect something. Immediately upon pulling off the drive (cold engine) there was a constant, almighty diesel knock, at anything above idle. This lasted for the ten mile journey, although wasn't quite as bad by the time I arrived.
I then went to Halfords, and put in almost a litre of wynnes type extreme clean treatment. The tank was just dropping onto the red at this point. I then took a more scenic drive home, and gave it a proper Italian tuneup.
Upon arriving at home it sounded almost normal. I guess the test will be, what it does on the next cold start, but, any ideas?
I know the earlier mondeo's were plagued with injector issues, but having done some reading, it appears that the engine in my car is supposed to be a bulletproof Peugeot diesel.
No noticeable power loss, no smoke, no EML, running fine. Just noisy. It's definitely diesel knock, and the oil level is fine.
Any further ideas please chaps?
