gwhite73 Posted July 18, 2014 Share Posted July 18, 2014 Hi I have a 2010 Mk7 1.4 diesel and I was driving on the motorway for about 2 hours yesterday with the air con on. Everything was fine until I got off the motorway and noticed a stange noise. It sounded like a grinding noise. I pulled over and revved the engine and the grinding sound got worse as the revs increased. The noise appeared to be related to the air con as when I switched it off the noise went away, but came back once I switched it on. At this point I noticed I wasn't getting any cold air anymore. I switched the engine off and left it for a while and now the grinding noise seems to have stopped. But when I switch A/C on, the fan comes on but I don't hear the "click" of the compressor coming in, and I don't get any cold air. Does anybody know what could be wrong? People have suggested it needs re-gassing but it sounds more serious than that to me. thanks! Quote Link to comment Share on other sites More sharing options...
btmaldon Posted July 18, 2014 Share Posted July 18, 2014 Sounds like the compressor has seized. Have you had the gas topped up recently. If so they should have put in PAG oil at the same time to lubricate the system while its running. Quote Link to comment Share on other sites More sharing options...
gwhite73 Posted July 20, 2014 Author Share Posted July 20, 2014 Hi Thanks for replying No I don't think I've ever had it topped up. I agree with you the noise sounded like something was seized. Based on that do you think it's fixable or would I probably need a new compressor? Thanks! Quote Link to comment Share on other sites More sharing options...
