As per the title, I noticed yesterday when trying to de-mist the windows that the ECON light won't turn off. From a search this sounds like the air-con is not working for some reason. I did a scan with VCDS and got only this error: Address 08: Auto HVAC Labels: 8P0-820-043.lbl Part No SW: 8P0 820 043 AD HW: 8P0 820 043 AD Component: KlimavollautomatH19 0360 Revision: 057901 Serial number: 8P0820043AD Shop #: WSC 00000 000 00000 VCID: 6ED87AA079B38B68C39 1 Fault Found: 00796 - Fan for Interior Temp Sensor (V42) 011 - Open Circuit - Intermittent Freeze Frame: Fault Status: 00101011 Fault Priority: 3 Fault Frequency: 1 Reset counter: 57 Mileage: 44463 km Time Indication: 0 Date: 2012.09.22 Time: 16:48:55 Freeze Frame: Voltage: 13.80 V Temperature: 32.0Â°C Cleared it and it hasn't come back (not that I would've thought this fan would cause the whole aircon system to stop working). The ECON light still won't go out. There are no other errors shown by VCDS. Is this likely to just be in need of a re-gas? I had a new air-con compressor last summer (2011) as the original had failed. I would've thought it shouldn't need a re-gas until next summer at the earliest. Is there anything else I can look at in VCDS which might indicate where the problem lies?
