Thread: Audi a4 2.0 tdi

    Audi a4 2.0 tdi

    Hi people, I'm new to this thread. I'm an owner of an Audi A4 B7, I'm having a few issues with it. It tends to judder/kangaroo whilst driving and when it's on idle the revs fluctuates. I've had diagnostics plugged in but isn't coming with any fault. I've also cleaned the EGR valve and the air flow mass. I've changed all the filters on it also. Can someone help me pleaaaaaaaase.

    Temperature sensor? My golf's idle used to go all over the place changed that and now it's sound and pulls a lot more evenly

    I agree i have a a4 05 plate 2.0 tdi that I changed the engine management coolant temperature sensor not the gauge one and it did the trick

    Would the temperature sensor cause it to judder if it was faulty? For some strange reason the car only judderes under 2000 RPM.

    My idle used to bounce around everywhere and used to be underpowered would drop power throughout the rev range, there only Bout 6-10 quid so ya ain't lost out much if it doesn't work :/

    Sweet let us know how it goes, be prepared to loose some coolant whilst replacing it

    I forgot to add, a few days after I bought the audi the seller decided to tell me it had run out of diesel a few days prior to me buying it. I'm really hoping its not the diesel pump as they cost too much 💰💰💰
