Finally gaot the car back after 1 3/4 days. Everything seems okay so far, but I've only driven it a couple miles.
Well, here's what the service invoice says about the alarm installation:
"1998 Tech 5029 - Performed DWA alarm retrofit. Due to alarm retrofit, tech needed to update software in vehicle (including CAS). Upon completion of software update, the TEL/ULF and the AMP had failed to respond correctly. Tried to perform complete vehicle encoding and found that clip instructed to replace the TEL/ULF and the AMP. Disconnected CIP/SSS and performed battery reset of vehicle. Upon completion of battery reset, reentered progman and indvidually special measured AMP and TEL/ULF. Both modules updated successfully. Performed the entire vehicle encoding. Vehicle encoding successful."
Charge was $110.50. My regular SA had gone to California for an M3 dealer driving event; I will be discussing that with him when he returns.
