When I bought my 56 CDTI 150bhp Elite the other week, the only fault it had was the air con didn't work. (Great bargaining on the price though!) As luck had it a re-gas solved it, but the compressor makes one hell of a racket (sounds like the bearings have failed when it's engaged), I've got a few prices but they ain't cheap in any case. To keep the price down though my plan was to get the gas taken out the system and then replace the compressor/pump myself. However I'm wanting to know how bad a job it is before I go an get a replacement, any pointers or is it worth letting someone else have the agro?
