I just bought a 2004 XC90 T6 second hand with approx 100,000km on the clock. A couple of weeks ago, I noticed the yellow engine warning light had appeared and the engine was running a little roughly. I took the car to the dealer's mechanic as it's luckily still under warranty.

The mechanic indicated that it was a simple matter of replacing the injector coil(s) per the ECU. Over the next week before I could put the car in to be serviced the problems got worse: lack of power under full throttle, rough, coarse running, surging under light acceleration. The mechanic has replaced the injector coils, and the ECU indicates everything is in perfect condition. The car is also mechanically sound, however the problem persists. Has anyone experienced this problem, and if so, what did you do to rectify? Thanks!
