Well I have been a long time Volvo owner through the years. I saw a XC90 and feel in love with the SUV. Found a deal on C-List for a 2004 XC90 2.5 with 173K for $2500 the previous original owner was prior military as I. We communicated for a couple of week to confirm a meet time. I was told that it was driven by his daughter for a couple of years therefore I figured that it would be a safe investment for my 2 mature kids 21 and 18. Well now the down low on what I have found the XC need. (4) rotor and brake pads, lower motor mounts, rear wheel bearings, strut mounts , AC compressor clutch replacement. I feel all was not disclosed prior to purchase but that is ok. Well after a week of driving awaiting for parts arrival the XC 's instrument cluster went dark cutting on and off then the car went into limp mode . I made it home safe but feel tis is a sign of the CEM module going bad. I have a 2002 XC70 sitting with a bad title. Are the CEMs units interchangeable and will I have to have it reprogramed ? What other parts can I use from the XC70. Sorry for the rant this is my first post here. I am not blaming the seller, I should have used the preinspection list.
