Hi all,
Having a bit of a nightmare with my A3 2.0TDI.
Needed a replacement turbo as the one on it was on its way out, opted for a hybrid as it wasn't much more than a normal replacement.
Now when my tuner is trying to tune it he says the turbo is 'doing the opposite' to what the ECU is asking of it, i.e. boosting when the ECU isn't requesting boost, and not boosting when ECU requests it.
We don't think there is a boost leak as the turbo makes good boost, just at the wrong time.
Replaced the MAF, as it eventually threw a code related to this which is resolved now.
Currently back to the stock file which is only putting out ~120bhp which is below stock of 150.
Any help, suggestions, or things to check would be appreciated.
Thanks!
