I don't see any problems with VD Ac Compressor.

- My 1998 528i Denso (it was a VD compressor from factory) lasted until 160K when it made noise, so I replaced it with another Denso ($220 for parts). Id di it myself and I am now at 180K, zero issues.

- My 2006 X5 3.0i with 135K, the Calsonic Kansei compressor is still fine. If and whenever I need to replace it, I'd stick with whatever came with the car, in this case, Calsonic Kansei brand name. However, browsing FCPEuro website, all I see are Nissens (which is probably OK) and BMW Genuine brand.
