VW TDI P007AF N75 Test 1

[@bigace109]

Yes the turbo actuator had to be replaced. The rubber diaphragm leaked air and resulted in the vane actuator not moving as much as what the ecu requested.

Is this possible on 1.8T engine??

What was the solution? Only 10 mbar difference between open or closed position.

[@rpaull3]

does that mean its a bad n75?

[@TheBelu57]

I dont understand you must press the brake pedal and test the turbo actuator..?!!!!?

[@bigace109]

Riciu Adrian yes to see if there are leaks in the diaphragm
