Took car in for the obligatory out of warranty MCU Failure and called me today to ask for a waiver as there is an aftermarket car stereo in the car and this may be the cause as the MCU is HIGHLY sensitive yada yada yada. The implication is that if you do anything to the car it could cause it to fail.

I have never heard of this before and have had aftermarket car stereos in nearly every car I have owned and have never been asked for a waiver. attached is the waiver....

The SA claimed that they couldn't tell why the MCU failed and it could be the aftermarket stereo wiring (connected to high level front speaker outputs and battery!). apparently MCU is dead dead (ie not communicating) which I have heard is sometimes the case due to memory write failures.

Anyone had any waivers sent to them?
