I just bought a 2004 Vovlo XC90 2.5Liter Turbo. I had it checked out before I purchased it and all was well until a couple nights ago. My wife went out to start it and all the electronics were dead. It started and she was able to drive home but it has lost all its power as well - Extremely slow and sluggish. I found a plethora of issues with the T6 model, but couldn't find much on this model/issue. All I found was maybe a bad ECM (Electronic Control Module). Anyone heard of this or know if it is the ECM? Also, If it is the ECM, can I replace that myself (I am moderately mechanically inclined) or since it is electronic does a mechanic/dealer have to plug it in or reset a new one to work with your car. Any insight is appreciated; thanks! KW
