I dropped my 08 XC90 V8 off at the local shop to have them look at the AWD system. I noticed it a few months back that it seemed like the AWD system wasn't working and the traction light would flash a few times. Well it turns out the AWD is not working, and the tech was able to turn the prop shaft by hand. Tell tale sign that somethings up, figuring this would be an expensive fix the quoted me a minimum of $1200 depending on what they find when they get in there.
My question is and I know it hard to say without opening the car up. What would be the normal area of failure here? What would be the worst case failure? I would hat ewfor them to open the car up and it ends up costing me $4K for all this. I'm worried that it would be the whole transfer case. Unfortunately it being a V8 the sub frame and exhaust look like they have to come off as well.
Also it looks like the valve cover gaskets are seeping a little, AC is in operative (need condenser replaced), has a transmission shudder (trans flush?), and I have catalyst inefficiency code. I've had the car since September but already it looks like its becoming a money pit.
What would you guys do?
