Was anything else done with the car when it had the pump replaced becaue if you put the same part #(or variant thereof) back in the car as the one you took out then it would stand to reason that the same thing should happen, unless something else was changed as well.
Anyone notice anything different about the driving characteristics of thier car after the work when compared to before? Changes in how the car accelerates, or runs at WOT, or how the turbos seem to kick in. Gas mileage changed?
I gotten my recall done earlier on this year. I used to hear misfires when at first gear after I pressed the accelerator and let it go abruptly. This is no longer there.

Mileage stayed about the same.

No issues with starting, cold or warm outside temperature.

Turbo is as usual, responsive and fast.
