Hi all,
I have have an audi 1.9tdi 54 plate which goes into limp mode in heavy rain and am a little confused to as what it could be as I seem to be going back to the garage on a regular basis for answers each time, so far I have had the following done:
1. Accelerator pedal replaced
2. MAF sensor replaced
3. Plenum chamber unblocked as it was holding water
4. Glow plugs changed
5. Plenum chamber cover to stop any excess water draining into plenum chamber
I have taken it back to the garage and they now believe it to be a turbo issue i.e to much over boost and the turbo needs replacing? However I am not really convinced as generally only goes into limp mode in the rain and on the motorway. However when I pull over and restart and drive in cruise control I have no issues at all? So how can it be a turbo issue? If it was would I not be having the same problem when driving in cruise control?
This problem is seriously doing my nut in as the guys at the garage pretty much only go by what the computer says? I assume I've had these errors from the plenum chamber being flooded but since that has been cleared I don't understand what it could be and am losing confidence in any mechanic at the moment as each has a different answer each time!
I would appreciate if someone has ever solved this issue on their A4 and could possibly point me in the right direction in terms of solving it.
Many thanks in advance
