Problems with a lot of idicators, help please

This Saturday I replaced driver side front airstrut on my 2002 AR and 2 O2 sensors. 10 minutes after I picked up my car from the shop I had a whole bunch of lights come up on my dash:

EPC
Suspension
ESP
ABS
Check engine

Took it back to the shop today and the redouts on the diagnostic computer were:
check engine, Code 18047 - Throttle pedal position sensor. Not a plausible Signal.
ABS - Throttle position sensor G69
ECU trouble code 1856.

The guy could not get into any other system with message something like "communication can not be established".

Any ideas?

are you chipped? solder in type?

or perhaps you clips a line to the esp sensor when you did the air springs?

No the car is stock '02 2.7T M6 with about 107K. I did not do the job myself, had it done in a shop. Can you suggest how to check for "clips a line to the esp sensor"?

Forgot to mention, the car was driving fine on Sunday and Monday(except for all the lights), but today I have severe power loss. The indicators also went off after I drove it for about 15 minute and restarted, but all came back on after another restart.

Thanks

power loss is the result of the problem. It called safe mode.

Being the car was OK prior to the repair.. go back to the shop and let them fix it. They caused it.

I would also expect them to take care of this but if they aren't set up to trouble shoot you may have to go to the dealer.

Are you using a standard obd-ii reader or vag com?

Thanks for you replys.

I took the car to the dealer and it ended up being a) a coincidence and b) throttle body. The dealer said that it had nothing to do with job done. Since my regular guy could not diagnose it himself (and I was charged by the dealer $150), he is not charging me anything for the labor to replace the throttle body (quoted $447 by Audi).
