If your engine light is on,your car is waiting to tell you whats wrong.
Get it plugged into star diags for the answer.contact a MB specialist
for this service.

When the engine light comes on the ECM stores a snapshot of all the data readings from every sensor. STAR - and indeed any OBDII data code reader - can view that snapshot and the operator can see which sensor was showing an abnormality at the very moment your car's computer identified trouble. In many cases the fault code can reveal the very nature of the sensor's complaint, more than just "a judder" it could show "misfire cylinder No 4" or something.

Your garage should have reported the fault indication to you before cancelling the fault code by resetting the light, but perhaps they thought it might be a temporary glitch worthy of a second try?

As the car is a C32 I think it's a good idea to begin with the inlet air temperature (IAT) value recorded at the moment the engine light came on and the ECM went into limp mode.

Both fuels.....?

Oh no, not a hybrid C32?
I weep when I see an AMG badge on a BlueEff diesel. If someone has corrupted a C32 I'll be getting headaches.

don't know they pissin me round going to a approved lpg dealer with a good rep in Rochdale Monday see what he say driving now seems ok still gas smell so just on petrol for now will let you know

 

[simontyson]

it was hmm bargin prices that the only reason why and still goes like **** of a shovel on gas

 

[T3RVO]

Aha. So it's an LPGAMG.
Not something that would attract my interest. Fuel economy isn't usually a prerequisite of AMG owners.
Good luck with it - I still suggest taking a look at the inlet air temperature on any Kompressor AMG just as a routine check-up.

got it back from gas center they say all fine on gas side the fault is on the petrol side he says slight misfire when ticking over ??? so going back to merc now see what they say any one know of any good mechanics in Oldham area
