Hi guys below are my problems for my Audi A4 TDI 2002
When Idling and car has warmed up. Loads of black smoke comes out when it is revved hard (actually marks the road with black soot ) and at night against othalso smokes when pulling away from lightser cars headlights
Poor Mpg (average 30-35 mixed, driving like an OAP)
While driving can sometimes feel a slight hesitation(usually under 2k)
I had my friend to have a look at it and he could not find any error codes but he was not using VAG COM but a hand held diagnostic tool.
He disconnected the MAP sensor (not maf) and we revved the engine hard and this produced hardly any black smoke , As soom as we reconnected the MAP and revved it hard the black smoke came back and was quite a bit.
Disconnected the MAF and no change apart from no turbo when it is driven disconnected.
The Turbo wastegate ppe seems to be fractured.
The EGR valce and MAF could also be the cause.
Can anyone help me out please as I want to get rid of the black smoke and improve the cars MPG and most be MAP sensor related as it hardly smokes when its disconnected?
