Hello all
March/2006 Merc ML 320 CDi
This is a question about my friends Merc ML, which hes not had for very long but the troubles have already started.
Within the first month of buying it the turbo failed, so he got a new turbo put on. This was about 3 weeks ago and its never ran right since. The turbo has been checked and re-checked and its fine.
So he took it to a Merc Indy who had it for over a week, pulled all the fault codes and then couldnt really do anything with it. Maybe it was too much for them, but they THOUGHT they had it running right and then it went back to square one the day my mate went to pick it up.
Basic problem is that it seems to have lost a lot of power, and sometimes the power will kick in for a short while but then cut out again, and so forth.
Having taken it back off the Indy's he then took it to the main dealers.
They came back the next day and said its 80% chance that both the cats are now clogged as a result of the failing turbo and that would be the main cause of the lack of power. They said they would start by replacing the cats and then see where they go from there as the diagnoses is showing a loss of pressure in the exhaust system . . . . . then they also said £2,000 to do it all!!!
So i was wondering if it would be better to de-cat and remap it as that should surely free up any clogging that is present in the cats?
How much would it roughly cost does anyone know?
