Aircon died - any recent experiences?

I had no A/C recently and checked the fans with the A/C switched on. The fans weren't spinning so I thought it might be the compressor. Took it to VW, they diagnosed it as a faulty high pressure switch that was cause the gas to leak out. They fitted the switch, about £100 to supply and fit but was done under warranty, now all working.

Thanks, useful. I assume it was a used car warranty you have then?

The fans will only come on if the compressor is being energized... If you do have a faulty pressure sensor or low pressure then they wont come on... worth getting it tested for gas first m8.

Agree with you on the 2 year re gas... i have just swapped my mk4 150 gti diesel after owning it for the best part of 9 years... re gassed once and worked flawless in all them years

Same with me - it's that time of year again............. warm air and resorted to windows down. Will be checking fans and hissing tomorrow   Hope its just  regas/leak or switch.

I have been told that the worst thing that you can do is not use it... something to do with the oil they add to the gas lubricating the internals and seals...  I used to leave my MK4 on auto all year round and will be doing the same with the MK5 ... we will see if this one last now a new compressor has been fitted
