A4 1.9 TDi white smoke when accelerating on motorway and loss of power
I've recently started seeing smoke coming from the back of my A4. It happens mostly when accelerating on the motorway. When i accelerate I can see white smoke coming up the back of the car and behind me. It's not a huge could to put people behind off but it is very noticeable in the rear view. I have also noticed a slight loss of power when the smoke appears. When idling there is no smoke. the car sounds fine at all times.
From reading a lot of other posts on this forum it seems like I might have a problem with the turbo? It doesn't sound like a head gasket if it only happens on acceleration right?
Any thoughts or ideas would be really helpful. I haven't yet checked the oil level / colour.
