This morning on my way to work my 2006 2.5T XC90 engine lost major horsepower. I barely could creep ahead once the traffic light turned green. The exclamation point on the dash was lit and the error message said "Reduced Engine Performance". I sputtered to the curb and put the vehicle in park. I depressed the gas pedal several times all the way to the floor with little reaction in engine rpms. I then shut off the engine and restarted. After this the warning lights went out and the engine ran fine. The outside temperature was -7F and my vehicle had been running for about 5 minutes.

 

I just got my XC90 back from the shop. $930 for the complete repair.

The throttle control module/housing was shot beyond repair/cleaning. They replaced it and did the required software download. No fun paying for this fix only 2-1/2 months after I bought it but there was no way of knowing. I had the codes read before and no problems reported until the failure.
