Hello there! My 500 SEC needs to have the aircon converted from the old R-12 system to R-143. Is there anyone out there that has had this done? What does it involve, how much would I expect to pay. I'm wondering if it's cost effective. I would be grateful for any advice. Thanks in advance.

No I haven't, to be honest I wouldn't know where to go or who to trust.

This lot offer a conversion for £80

It seems that the idea of needing a new compressor etc etc for R134a isn't true. It would seem that the process is to thoroughly evacuate the r12 system (which is expensive to do legally), the old system checked for leaks (natch) and cleaned / serviced, the direr replaced and the R134a (+ an additive) put in.

[edit]

You might see some mention of a a 'drop in' replacement for r12 but IIRC, when I was looking at doing my '89 535i, I was advised that it doesn't work too well.

Look for "car air conditioning" in Yellow Pages. There are loads of specialists around the country.
