In my TD42 the bearing (i think) is very noisy when A/C is cutting in, but OK when not cooling.
The noise is opposite end to the pulley .

The A/C experts !!!! say it may be pressure valve or something else in back plate of compressor
How is it possible to verify this without degassing the system.

Thanks for that, very interesting but I am still of the impression that the noise is Back of compressor not pulley end, will have another look tomorrow.

Clutch bearing in the compressors is very easy to replace if you can get access to it. This usually means removing the alternator. Unfortunately if its the shaft bearing, you are going to have to remove the refrigerant gas from the system. If the bearing is noisiest when the air-con is off, it is most likely the clutch bearing.

The bearing or whatever is noisiest when the air-con is ON, it seems to resonate in the pipe coming into the evaporator coil , real bad.
The evaporator coil (behind the glove box) was replaced about 18 months ago and since regassing the noise is BAD.!!!
