Last night I picked up a (relatively speaking) low mileage 2004 S60 2.5t awd. I have had a 2004 XC70 for a few months and been through it pretty thoroughly, understand a lot of P2 issues now but certainly not all!
I know I can google many of these issues as they are out there and I'm not looking at re-inventing the wheel in this thread. However, since I think most of these issues started because the car sat unused for a long while, someone may have some insight as to where to look first vs. me running through a lengthy diagnostic tree. The car has only seen 19k miles in the last 10.5 years (based on timing belt change date/mileage), and it looks to me like it has seen very, very few miles in the last four years based on the date of the last set of new tires and the current (near new) tread depth/condition.
I got the car for my step-son as an upgrade from his "starter car" Honda Civic. It has 130k on it and drives, shifts, steers, brakes, and rides great: no drivetrain or suspension issues of immediate concern. Timing belt and oil trap have been done and no major service required there. No exterior issues (other than typical plastic refurb, etc) and it will clean up and look very sharp. I will still go through and service things thoroughly before winter (haldex fluid/filter, diff fluids, etc.). The punch-list of things I need to fix that I don't know immediately how to fix are:
- sunroof inop. (said to have worked a short while ago and just stopped).
- Air bag urgent svc. light
- Cruise inop. (maybe related to airbag? I could see the logic of ecu disabling it with that warning) - If I hit the cruise button nothing at all happens.
I know these are likely general P2 issues and not purely S60 but thought I'd ask here first. And again I ask vs. searching as I think the root cause is disuse and not mis-use or over-use, and someone might have some insight into that and save me a lot of time.
2nd topic is: Are auxiliary transmission coolers considered wise on these, as some XC70 owners feel? I did put an aux cooler and inline filter in my XC70 six weeks ago, but I wonder if the lighter weight and non-Geartronic transmission (this is non-geartronic) make it as valuable here on the S60? I'd love to skip it if not needed but I would do it if the cw is that it's a smart move.
As an aside, I really enjoyed driving the car a little hard (ok actually kinda hard) on some back roads last night on the way home; I could see an S60R in my own future...
