Title: Aircon pump for mk5 golf sport tdi dsg
Post by: ddrgolf on August 06, 2018, 09:32:12 pm

Hi all. I have a 2006 mk5 golf sport tdi with climate control. Aircon not cooling. Had it pressure tested (thought it my need regas) and ok but failed due to pump not switching in. Any ideas why?. Can't find a fuse or relay for it. Maybe pumps gone? Pump is 1K0 820 803 S. Anyone know the difference beTween S and other suffixes? Are they interchangeable? Is an easy home fit? Hope someone can help as it's a great car but dealer prices too high for value of car.

there's a solenoid on the pump that you can replace for less than £14 I've put the link below. could be this.

Apparently fault is in climate control panel. Got a used replacement and fitting looks easy to fit but is it a straight replacement or does it need to be programed with vagcom after fitting. Anyone tried the ebay type vagcoms? are they any good?
