Was getting the following fault followed by an EPC light/loss of power/TCS light.

P1542 MIL code, 17950 - Angle Sensor 1 for Throttle Actuator (G187), P1542 - 35-00 - Implausible Signal

Tried re-seating the connector followed by running an adaption, to have it come back a week later. Then ended up cleaning up the carbon resistors inside the electrical cover, which seems to have resolved the issue for over a year now. Was going to do a write up, as I only see people recommending to clean the butterfly valve on here. But it looks like someone on passatworld.com did a fantastic job already. The task is identical on the beetle.

This will apply for Angle Sensor 2 for Throttle Actuator faults as well. It could very well save many from spending money on a new throttle body, when this will resolve the issue. Just wanted to pass this along to some fellow Beetle owners.

And if after cleaning you still have issues and need to buy a New throttle body, I discovered a money saving alternative.
The part number for a Beetle is listed at $1100 ( Part 06A133062J - throttle body Beetle; 1.8L)
But there is a Generic part that covers ALL the 1.8T, and it was only $132 !!!
The only difference i could see was the Vacuum port was brass, instead of the original plastic.
Have had it on for over a year with no trouble codes.

Issue was resolved over a year ago, with nary any issues. Just wanted to pass this along as I could not find a writeup on here in hopes of helping someone else.

I do find it interesting my wife's throttle body assembly has a brass fitting, never knew some were plastic.
