I know about Xemodex and the excellent service they provide rebuilding ETM and other Volvo electronics but did i read someone on here can exchange or knows which ones are swap-able between cars without getting into compatibility issues?
On my last road trip mine S60 B5244s gave me a scare when the accelerator pedal kinda felt dead and engine hesitating, fuel mileage fell off a cliff. No Codes/MIL though.
After safely pulling off the highway and parking. Turned engine off then back on to reset it ran fine the rest of the trip.
I had my wife's ETM rebuilt at Xemodex for $600. and her car idles glass smooth now. It was always hunting at idle before.
I don't feel like spending $600 if i don't have too.
