W204 c220 estate timing chain

[Pippen007]

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

Give Steve at Avantgarde be Bristol a call but £1600 sounds a bit steep to me.
Before doing anything get codes read on Star.

Hello and Welcome,

As per above, get the error codes read and see form there - without that it's an expensive guess

Firstly, Welcome!

Secondly, in answer to your questions:

A) if there is a current timing fault code, then yes, this will prevent regen, but you need to ensure that this is the case, and they arent just chasing their tails with a DPF code.
b) Its a bit on the high side, but not too far out of the ball park considering the labour involved.

LK, Blobcat, Umblecumbuz and Alexanderfoti thank you for your responses. I will give Steve a call tomorrow, need to confirm with the current independent what diagnostics they use - I suspect it isn’t’t STAR.
Cheers

thanks for your help

Further update.
Avantgarde were fantastic, diagnosed dpf pressure sensor fault. Booked in for repair next week.

Once again thank you those who responded.
Cheers
Scott

Sounds like it's worth getting a new tensioner fitted while it's in.
