I apparently have a faulty Electronic Control System in my 2000-V70XC. This is according to the dealer and the ECM codes. I am wondering if anyone can tell me if this fault is normal after 80K miles and if there are other conditions that can cause the same fault code. I am not happy about the cost of ths repair, $800, and feel this component should last the life of the car. Has anyone had the same experience or know where good information about this system can be found? The electronics has taken the DIY out of everything.

I had the same problem on my 00 XC SE and luckly it was at 48k miles and still under warranty. Knowing the part is faulty Volvo should replace it a no charge but of course they won't.

Next car will be a Audi Avant. They have great service and stand behind their warranty.

Good Luck

Not at all unusual, the codes say "internal fault" and the only solution is to have them replace the part.
Even if you try doing it yourself or have another shop replace it, the car will not start until software is installed for the new throttle unit.
The part was replaced by a better, improved part starting with '02s model cars but not before then. Can't be converted either.
