Hi all, im still on the quest to sort out my "cylinder bank 1 lean" problem.
Today i took it to my local VAG specialist and they put the car on the diagnostics and again, it came up with the same thing.
I have no inlet air leaks, nor exhaust leaks.
The diagnostic print out gave the following possible issues:
Inlet air leak
Exhaust gas leak
Fuel pump (g6)
The service chap also said to check the valve on the back of the turbo?
I have checked the diverter valve, but did not know there was another valve on the turbo, he says there is a diaphragm that splits?
How true is the above?
If so, how easy is it to change?
