Hi, The aircon has not been working in our Octavia 2.0 TDi for a while now. When I scan for fault codes I am getting the following: 00988 -044 Lamp for Brake Light: Right (M10) sporadic 012-Electrical Fault 00834 -041 Signal for Activation of Heated Rear Window sporadic 0009-Open or 02071 -036 Local Databus sporadic 004-No Signal/Communication 01320 -036 Control Module for Climatronic (J255) sporadic 004-No Signal/Communication 00059 -044 Terminal 30 for Interior Lighting sporadic 012-Electrical Fault 01520 -040 Rain and Light Recognition Sensor (G397) sporadic 00926 -043 Terminal 30 sporadic 011-Open Circuit Everything else appears to be working ok, LCDs & LEDs working on the control, fans operating, flap motors operating, just no cold air. Have had system re-gassed twice and checked for leaks with none found. Any thoughts? I'm wondering if it could be as simple as a dodgy earth somewhere, or maybe something more sinister... Otherwise, I'll get in touch with my friendly local member and get a full scan done to see if that helps identify the root cause. Cheers, Alan

What if the paper clip does not stop the warning light? The wiring to earth is good. What should the supply voltage be? I would expect 12V which I am not getting so thinking I may have a dodgy wire from the instrument panel... I have tried three expansion tanks with no success.

Thanks for the ideas. I assume if the nut does tweak up I should then replace it and torque/angle it up properly? Cheers, Alan Sent from my iPhone using Tapatalk

I'm physically turning the driveshaft but am seeing this movement on the hub nut whilst the hub remains stationary! Sent from my iPhone using Tapatalk

Hi, it seems that my off side driveshaft is quite sloppy in the hub splines. I can move it slightly, a degree or three, when holding the hub securely. Clunks when I do this, is noticeable when driving! The hub nut is tight! Before I pull it all apart to investigate, are their any obvious or known causes of this? Unmatched driveshaft and hub? Dodgy hub nut? Any advice gratefully received. Cheers, Alan Sent from my iPhone using Tapatalk
