Hi All
After a bit of advice, please.
Have a c220 w204 estate 2010 model with the om651 engine. It has covered 220000 miles - got it when it had covered 120000.
I have read about the timing chain issues, with the rattle at startup. Mine has had this for a little while, although have not done anything about it. On a recent trip back from France the engine management light came on and when taken to my local independent they diagnosed a DPF fault - in that it was at 300%.
I don’t know if they have STAR, but they “cleaned” and reset the fault. Having driven less than 20 miles the engine light has come back on. I have contacted the independent and they believe it has come on as the timing is “probably” out due to a stretched timing chain. I assume this is feasible.
Their “go To” tech isn’t in till Wednesday to discuss fully, but they are suggesting a timing chain replacement - I assume with tensioner (s) , guide (s) and “toothed wheels?”. The suggested cost is £1600........
At this stage they don’t think it is an engine out job.
My questions:
A. Is the assumption of a stretched chain affecting timing and therefore DPF not regenerating (their assumption) correct?
B. Is £1600 reasonable? I know it is variable with what has to be done.
Any guidance gratefully received.
Many thanks
Scott
