Question about 2006 Volkswagen Golf

1 Answer

Air conditioning failure on a 2006 volkswagen golf mk5 tdi with 32k on the clock. System has been recharged and no faults are showing on the diagnostic with all relevant components getting 14.2v. The car did recently break down and the rac guy said it was showing code 802, "low pressure switch for the air con F73". Garage is suggesting changing the compressor. Anyone have any ideas.

The condensers are infamous for developing leaks on the VW's. Before replacing Compressor have the shop do a vacuum test on it to make sure its holding pressure. If a compressor is bad the system will still hold vacuum. If the system does not hold vacuum then the problem is not compressor but in the condenser or lines with a leak. Have the shop do a leak test on it ONLY after vacuum test.
