I have a TD4 LWB 02 plate all has been ok. It has 46k on the clock, due for service soonish obviously. I was coming round the m25 the other day & noticed a kind of sound coming from behind the glove box which sounded like air being pushed out. The turbo appears to be whistling still. There is no smoke or anything, and I can't see anything visibly wrong in the engine compartment! It only happens when I am eccelerating, doesn't happen just revving idle? Haven't noticed any other symptoms yet. Are there any filters related to the turbo?
Any thoughts?
Cheers
Adrian :roll:
