Q&A

It's a well known problem. You can't service the ETM, only replace.
Volvo was pushed to extend the warranty on the modules, so it might be covered for you.
The dealer usually clean the throttle body first for a bunch of money , than download a software update for the ECM. Mostly it's a waste of time and money (but this way they could charge you some $ to recover some of their loss on the recall) and at the end they will probably replace the ETM for you. If your local dealer won't be helpful, call Volvo of North America or the NHTSA hotline, phone numbers are below.
