Hi all recently had my air-con re gassed but still it's not working the man at the garage said it could be the pump or a control module and said he can't tell so contact skoda.They want £80 just to diagnose the fault was wondering if there is any other way to find what's wrong ?

Find a local member with VCDS to scan the car and see what faults are logged.

Check the torx centre bolt in the compressor pulley...as is well documented on here, it does frequently come loose (only by a few mm), but that does cause it to stop working. Just had this very problem on mine, and it is a very simple job to tighten up, but you will need a ratchet gun (electric or air) just to nip it up

Hi could you possibly show me a picture of this please ?

What if it's the control module how much are these to buy and where are they fitted ?

I just bought a 59 plate VRS, same issue. Local aircon guys re gassed, ran a diagnostic, couldn't get to the bottom of it, so I took it to my local Skoda dealer.

Their diagnostic charge was £45, the report said the compressor bolt was bust, needed to replace the whole thing. They quoted £1350.

I phoned around a few places, my local mechanic said he'd do it for £420. He ordered a new compressor, fitted it, re gassed, still no cold air :(

He said the only thing left to change was the pressure switch, that was another £30, did the trick. He said that it could have been misdiagnosed, or could have both been faulty. On days like this though, it's money well spent!

In the pic the bolt has come out a fair bit. The bolt only needs to come out a tiny bit for the pump to stop working. This is only the Delphi pumps, normally fitted to the last of the PFL octavia's and the FL octavia usually with the CR engines (1.6cr tdi/ 2.0cr tdi)

The A/C control module in part of the A/C controls. The is no seperate C.unit

My friend said it ain't worth checking my pump as it's not the clutch type so shouldn't be loose ?

Clutch unit or not, you still need to check it. If the bolt comes loose, the pully will just spin on the shaft of the pump and not turn the pump.
