What info can anyone provide about the software updates from the dealer. I bought a 2002 S40 with 87K miles a few months ago. I love the car but the longer I have it I'm noticing these quirks A(some of which I see in this forum). (1) Two CEL codes P0128 & P0130-reset them both and they haven't come back. (2) the fan on the A/C is crazy in auto mode and the A/C compressor light comes off and on without the fan on. I've seen a couple of threads where the updates are free from the dealer and only take a few minutes. Is there a way to tell what version my car has and what version is available?

A/C in auto with fan going crazy sounds like an in-cabin temperature sensor issue...it may just be dirty and need cleaning. It is the first little slot on the horizontal dash just to the left of your climate control buttons...look for the little rectangular piece with a slotted cover. Try using some compressed air and blowing any debris out of it. If this doesn't work, then you can pull out your Climate Control unit (after pulling your radio out first and unscrewing the bolts from under the climate control) and pushing out the temp. sensor from behind the dash. In regards to your car's "free" upgrades, this is doubtful unless there's been a recall for some reason. Best bet is to call your dealer with your VIN# and just ask them what software programs have been available for your car and which are free. Good luck and let us know how things go.
