I bought a 2007 XC90 3.2 AWD with 180,000 miles on it. It was quite cheap, and it drives quite nicely, but it's got quite a collection of issues. Can you give me some nudges on these?
1> I've got it scheduled for a serpentine replacement at my local indie Volvo shop.
2> Both of the rear ABS sensors are throwing codes (and one of the wheel bearings is shot). Should it be enough to replace these to get my ABS back on line?
3> The dreaded Steering Angle Sensor is associated with a goodly set of codes. With the shop quoting $650 to fix it, and the part on eBay showing up in the $350 range, and (from what I've gathered here) needing to be programmed at the shop even if I DIY it, I'm not going to be saving a lot of money doing it myself, right?
4> I have the AWD oil pressure pump performance code, along with U0011400, P188914. If I swap the pump, filter and fluid, and at least tidy up, possibly replace the control module, am I likely to have a working AWD system, or is this liable to be a hole that I pour money into and get no love from?
5> My torque mount is worn but my engine mounts are apparently good still. I only see the one on the passenger side - is it copacetic to just swap that?
6> None (neither the front nor rear) windshield washer squirters work. The reservoir is full and I've checked the fuse. What's my next step for chasing this down?
7> The shop indicated that the park assist was inoperative, but at a glance I didn't think I had that feature. How would I verify one way or the other?
8> Are there obvious bits that I'm missing?
