I knew it was a matter of time before I posted an SOS!!!!

I owe a 2004 745LI with @ 49K miles..trully a garage queen.

Issue: AC does not cool

Diagnostic/from local BMW mechanic which I trust:

1. No leaks detected
2. AC has appropiate pounds of R134
3. LP side should be at 35, but it reflects 100
4. HP side should be between 225-250 shows 225 (this side is ok)
5. Cost to repair: $1669 with a BMW compressor or $1200 with an aftermarker compressor.
6. BMW is asking $2000 for a new compressor
7. Has this occured to anyone?
