Aircon problem?

[El-Cap]

Think the aircon has broken something on our Passat B8 estate. Started making a whining noise the other day. Took it out for a run and if you turn the aircon to low it sounds like Dyson vacuum. Also doesn’t seem to be cooling that well and the condensation was noticeable. Had the air con serviced last year.

Any thoughts? Compressor?

Is it likely to be expensive?

The aircon is a black hole for money because it can be a number of things.

My son's Skoda Octavia (most probably similar, if not same parts, as VW) went TU. Gave car to an AirCon specialist who did the evaluation....either compressor, this that or tother. 6 weeks later, everything attached to the engine replaced and £1300 he got the car back 'fixed'. The following day it went TU again. I did some DEEEEEEPPPP Googling...a £5 control panel switch module off ebay fixed it. Which would most probably have fixed it with the old parts.

Thanks. Hopefully it will be the cheap part
Going to get it booked into the VW dealer where the aircon was last serviced

Their quote will be most interesting.

Garage couldn’t find an obvious fault. Re-gassed system and put dye in so a trace can be conducted if it happens again. No charge
