2004 S60, about 140,000 miles.
Last week my son's S60 displayed Reduced Power message and he said it would barely go above idle speed. He limped home, turned off car and restarted. It was fine. He put on OBDII reader on it over the weekend and got no code (the CEL never came on).
Drove it for another week and it did the same thing today. This time he pulled into a parking lot, turned off engine, pulled codes again (again, nothing) and it started and drove fine.
Twice in a week is not a good pattern. "Rebooting" fixes it for now but seems like it could just decide not to go at all someday.
I've read about the electronic throttle causing the reduced power mode but posts seem to deal with older cars. Also read about silent warranty but only for total failure and right now we don't have any evidence.
Since the car does not log any codes how do I go about diagnosing this problem? Is there something to clean some such maintenance or do we suck it up and get another module?
