- In this video we look into why my 2002 Audi A4 has a severe lack of power, again... Please subscribe! / @stuiesgarage
As stated in the video, there are several ways to track lack of power. In my experience the major culprits may be the catalytic converter being plugged, the turbo failing, the cam chain not set correctly, or leaks in the system. I have anther video on the cam chain issue.
Wastegate actuator is a consumable in this engine and the 2.0. happens to most of those engines at a certain milage
Just bought a replacement, hopefully I’ll make a video on the wastegate repair
Great video! Did you end up replacing the turbo?
No! I took off the turbo, ordered a new wastegate on eBay and then welded the new wastegate on and reinstalled the turbo. Boost is back to normal! I wanted to make a recap video on this, will try to soon…

Got any idea how to solve P0171 on the 1.8t? I already replaced the crankcase Ventilation system that was obv. damaged but the fault code still comes back. *I also have freeze Frame readings if that helps
I have a 2004 avante with the 1.8t and sometimes it feels like its overboosting, so maybe i have the opposite problem... wastegate sticking ?
Possibly, or diverter valve?
@@stuiesgarage I will check that, thanks !
