I know that this problem has been reported many times on this forum. But I thought I'll update the forum with the issues I'm facing and get some insight as well
Last week my 2004 XC90 threw up a reduced engine performance error message and started stalling. Took it to the Volvo dealer who recommended an etm software upgrade, etm cleaning and changing some cables. $500 later, the error came back up again. The very next day after I got it back from the dealer. This time, the dealer recommended changing the ETM. Another $725 later, the error is back. After having spent $1,200 and not getting a solution, I'm hesitant in taking this back to the dealer. I think they are just guessing what the issue is based on the error codes rather than actual troubleshooting
Any ideas ?
