Hi All, I'm back :-) I've had the car scanned with VCDS. A couple of minor historical faults were found that did not come back once cleared, and were not related to the AirCon. Scan of the HVAC did not produce any faults either. I've pasted the log dump below - can anyone spot anything in the values that might push me in the right direction to finding the fault stopping the air con from working? Thanks.

No neither fan appears to spin when on the drive. I regularly do a 75 mile motorway run and the temp gauge always sits around 90 degrees. I can’t recall hearing the fan when I pull up after the run.

Thanks. I’ll see if I can find someone with VCDS to scan the car. I’d normally invest in a scan tool myself but the prices look quite high. can any other tool access the codes?

Hi All, Owner of a new to me Skoda Superb 2012 Elegance model. Purchased the car privately just under 4 weeks ago and so far covered nearly 2500 very enjoyable miles. Loving the car so far! I’ve got a minor niggle and looking for some advice and guidance as I do not know VAG group cars well at all. But have always found forums a great community and asset in the past. When I viewed the car I noticed the air con wasn’t as cold as I would like. The now previous owner advised the car had stood and probably needed a regas. I went against my better judgement and bought the car. Fast forward a couple of weeks and the newly found sunshine reminded me I need to get the car regassed. I took the car to be regassed and the garage went through the process taking just over an hour. The garage told me the system had too much gas in when they started, they had taken the old gas out and put new in to the correct level, but the air con was the same and appeared not to be working. They confirmed the system had no leaks and was keeping pressure. Leaving the garage feeling like I should have really pressed the issue of the air con further and kicking myself, I’m now looking to do any troubleshooting myself. So far i have: -confirmed there’s gas in the system -confirmed the system is keeping pressure -checked the fuses in the door panel and under the bonnet -scanned for fault codes (using Carista) - none showing for air con Is there anything else i should look at to try and diagnose or prove where the fault in the system is? I read on another thread (for an Octavia not Superb - unsure how different they are?) that the smaller rad fan in the engine bay should spin when the car is stationary to help cool the condenser - is this correct for the superb? Any help appreciated :-) Thanks
