Hi I am new member on this forum. I am in Markham ontario Canada. I have a VW Jetta automatic, I have read quite a bit of faq 1000qs. My problem is 2 fold.
Last year December I changed my Turbo as old one was leaking on out side and not working, with a new one. In the begining I could hear the turb spooling but lately I am not hearing it. and also I am
getting very poor milage about 600 km/ 45 liters. in the summer I had injectors and nozles serviced.
My car is not modified, automatic and has baout 2003000 km.
I have VCDS. Any Ideas or help will be greatley appreciated.

The first step is to use VCDS and log the MAP values, requested and actual. This is manifold pressure or boost. Gradually step on the accelerator pedal while datalogging the values. This will confirm if it's working as intended.

Also check timing and fuel injection quantity. There's a FAQ article showing how to do this, search hammer mod and look at part 2 of the timing belt article, ALH engine.
