If you get AC on the highway, but not in stop and go traffic? Then it's the aux fan.

If you could afford to buy a BMW you should be able to buy BMW Scanner 1.4 and the diagnostic cable. Any old computer running XP should be useful. BMW Scanner 1.4 is fairly easy to install and a scan is very easy to perform. A bad fan will show up in the DME module.

Perhaps a local Xoutposter can scan your X. I scan the X for a local poster and informed him that he had a bad aux fan. He found an indy to replace the fan and his ac was cold again.
