Weird issue with Gearbox ?
I have a problem with Audi A4 B9 2.0 TDI.
When driving for about 10-15 minutes the car starts to jerk/clunk a bit and the rpm does a down spike, it does that from 3-15 times and then goes away, when it does that the car loses power a bit, right now there seems to be no difference what speed you are driving or in what gear the gearbox is. There seems to be a link between the rpm, when it does it on the freeway with consant speed and rpm the down spikes and jerk/gluncking is mild and the car wont speed up properly, if the rpm is higher like doing a takeover the jerking goes more violent and it feels like you slam on the brakes for a second. Right now im not sure its the gearbox fault but it seems like a failing mechatronic. The car has no fault codes.
