Hello everyone,

I have a serious issue with my 2008 Audi A3 1.6 BSE petrol engine, that I have been trying to resolve for months now.
I have had the car for a while with no issues at all, and out of nowhere problems started as EPC light on and car going into limp mode. The VCDS scan showed 17950 - Angle Sensor 1 for Throttle Actuator (G187) Implausible Signal.
Naturally I ordered a brand new Throttle Body and replaced it but the issue persisted. The next thing was checking all the wires that lead to the TB, there seemed to be no issues with it but the shop replaced the wires and connector to the body and all seals of intake manifold for testing purposes. Still the issue wasn't resolved.
The next thing we did was replacing the ECU - still the issue was there.
I have also tried putting a used Throttle Body but no luck.
I have also replaced the throttle pedal sensor.

I spent way too much money on this so far and I have no clue what to do next. I tried to search for related problems on forums but there seem to be no results that would help me resolve the problem.

Does anyone have a clue what I could do or check, I would really like to fix this because I don't want to get rid of the car
