Ok guys got a mile from home and the light below came on? Read alover and it says(petrol vehicles only)
Mines diesel?
No change in performance at all nothing everything exactly the same no warning msgs . Only thing i think i can notice is a rasping noise from what seems to be from front drivers side in engine bay?under acceleration?

The last one has generated the MIL.
Check the rubber hoses from intercooler to intake manifold.

Cheers Alex was thinking hose related Back in black !!

Hi

I had this once with "engine reduced performance. Contact dealer" and it was a DPF sensor to replace.

Butin your case, you don't have this message, and you hear a strange noise, so may be not related.

So I think that Alex track is more probable.

Cheers !
