[s-cars] re AC problems

[George Verbryck]

OK I checked the compressor rpm channel and it reads 000 , engine rpm channel agrees with the Tach so.... am I looking for a connection wire to the climate control or from the compressor for a wiring fault? Also how do I reset the codes? I assume I can reset them by disconnecting the battery but when I did that in my V8 I had to reset the airbag light and I do not have vagcom and my stealer wanted $80 . Will this also occur with the S4? I checked the belt and no strange noises everything seems to be spinning nicely. Thanks for the help, George
