Hi, saw an old post of yours about a high pitched noise at the compressor. I have a 08' LR3 with the same issue. With the compressor cover off and found if I unplug the 6 prong connector (compressor exhaust, compressor temp, and motor temp) the noise stops. Consistently getting fault code C1A13-64 (AF) Pressure does not decrease when venting gallery. Any insight you could provide is greatly appreciated! Thanks, Brian
