Hmm, I believe the condenser fan runs anytime the compressor is engaged on all of my BMW's. Albeit at a slow or high speed depending on need. But, it runs. Why would you NOT want the fan on when the compressor is engaged. The more the condenser is cooled, the more efficient the a/c system will be. The more efficient, the more fuel that is saved as the compressor will cycle off more often.
