My 2008 A3 2.0 TDi has recently been going into 'limp' mode on infrequent occasion. Usually when it gets a bit of welly to overtake, or long uphill under power - no warning lights on dash and always recovers after restart (just a pain in the a$$ to perform in traffic!). Been getting a bit of the 'siren' sound for a wee while, which I assumed was the old 'sticky vane' problem. Tried a couple of turbo cleaners through the tank and ran with 2 stroke added ( local independent recommendation!) for a couple of thousand miles to no avail.
Is this likely to need a recon turbo? Is it worth removing to clean it - or even try good old 'Mr Muscle' via the EGR?
Although fairly competent with the spanners, I don't have the room or facilities to remove the damn thing myself ( I'm told that you need a ramp to give you the room to remove the turbo via exhaust tunnel). on't fancy trying it lying under the car on driveway!
Any experience in this area appreciated. What would you suggest?
