Seems to have been one of those weeks!! .....It was slightly hot today!! ...I usually turn the climate control off in my 02 Elegance TDI but as today was slightly hotter than normal I switched it back on, after about a mile (Of blowing out nice cold air) it started blowing out warm so I thought thats not right so switched it off ....then I get an almighty burning smell coming into the car and the the outside temp display goes from 35 to 40 degrees??? I thought the thing was on fire lol ...anyway stopped could see no flames but smell under bonnet was like burnt brakes / clutch drove home checked HVAC with vcds for faults....Nothing ...jacked up front, air con compressor spins by hand (Inner pulley) but when engine started and climate turned on does not spin so I am suspecting the clutch (Or electrical switching to the clutch) has burned out?

So my question is:.... does anyone know these clutch assemblys and how they go together and if I carry on driving with the climate turned off is anything likely to come apart or is the inner pulley competely seperate to the outer pulley which the aux drive belt drives???....just to add fans working ok too

Compressors are common for failing unfortunately. [emoji22]

yeah I accept that and especially in this heat but I can live without the aircon for the time being just want to know if the whole pulley is likely to come off if I keep driving it as I have a few miles coming up in the next week??

No mine was like it for over 6 months until I got a new one.

Thats made me slightly happier!!!....Cheers

I don;t know how common a fail compressor is,mine is still original from 14 years

On the MkI, the pulley tends to die rather than the compressor, but this can knacker the shaft.

Compressor failure is more common on the MkII.

I can't see why you "have to turn the AC off manually". In "manual mode" (Man) the interior fan can be turned off, and in "Econ" the aircon itself is disabled although the fan, blender and temperature functions work otherwise.

To be honest I never realised that the aircon stayed off in Econ mode (maybe I should heve read the book) and I only found out by accident that if you hold the fan down button in for long enough the display reads "off" and everything seems to stop. On the plus side the electric sunroof works a treat so until I can be bothered to sort it out I will just be opening that, Might even get a bit of a tan on the old boat race...lol

When you do that, you're turning the entire ventilation system off, not just the AC.
