Hi guys
I have a 2010 Tiguan 2.0 TDI CBAB the car has no power and is not generating any boost. I first checked the VNT actuator with a vacuum pump and this is actuating as it should in fact it will create some boost when I actuate it manually.
Next I checked the control solenoid and it was not opening so I figured it was dead and just replaced it but the new one was not opening either. I put an oscilloscope on and checked the signal its about 300hz with a 5% duty cycle and even when revving the engine the duty cycle does not change at all.
I am really at a loss on where to look what fault would cause the car to not try and actuate the VNT but would also not throw a check engine light or a code ?
Any help would be appreciated.
