Put my aircon on for the first time for a while as we managed to get up to a warm 11 degrees c. For some reason though the aircon is now making a funny metalic sort of rasp. Its not a constant noise, more like a pulsing sort of sound which seems to get slightly more frequent when you 2.turned aircon on. 3.made sure ECON is "OFF". 4.The fans do nothing then, after about 20 seconds, the one on the right-hand side as you look down (passenger side) runs very fast. This fan then. stops after a minute or 2, then starts running again at high speed. 5. The fan only runs at high speed like this when the air con is switched on.

Always Involved; Thank You Went to have a look to see i could find the switch next to the alternator.

It started bubbling, I cleaned it out as best i could with a wipe and flat screwdriver! My aircon had a minor leak and the refrigerant lasted about 8 weeks.

MK5 Golf GTI » Forum » All Things Mk5 » Mk5 General Area » Daft one this. But I noticed today a strange noise. If I have the engine running and fans to low with the air con off its fine.

I couldn't tell you if it had it fixed before I owned the Golf though.
