The problem is while driving, the EPC light turns on and the car runs poorly. The fuel trim becomes rich. It smells like petrol behind the car. This is the limp home mode that allows you to drive the car home.
If you stop the engine, the EPC warning light might go away or stay and after turning the ignition on in the car, the engine keeps revving up and down while in idle. The car cannot be driven at this point and it must be fixed.
These symptoms together with the EPC light and OBD2 scanner or VAG-COM error codes related to the throttle body mean there is an error with the throttle body itself which can be expensive or with the electrical wiring near the throttle body.
At this point it's a good idea to check the electrical connections on the throttle body. Steps shown in the video.
Engine faults found with the OBD scanner
17580 - Angle Sensor 2 for Throttle Actuator (G188) Signal too Low
P1172 - 35-10 - - - Intermittent
17952 Throttle Actuation Potentiometer Signal too High
P1544 - 35-10 this one is also Intermittent
Chapters:
0:00 Intro
0:08 EPC Light Problem
0:37 EPC Light and RPM going up and down on engine start
2:09 Check VAG-COM VCDS Engine codes for throttle positioning sensors
2:21 Drive-by-wire throttle body
2:39 Clean contacts on Throttle body connector
2:56 Connector wiring
3:06 WD-40 spray
3:13 Can check wiring but...
3:21 When you reinstall the connector make sure it clicks
3:31 Clean the WD-40 from the throttle body
3:48 Check if EPC light is gone and engine runs smoothly
4:18 Conclusion
4:59 Outro
