Air con issue with fault codes.

My Aircon won't turn on (eco light stays on).

Took it to a friends garage and he re gassed it but it still did not work. He said it could be the wiring but was not sure on the layout on an Audi (basically he only had a quick look)

Had it scanned a while back and have these errors

Address 08 auto HVAC

00483 control module for auxiliary air heater
013 check DTC memory
Freeze frame
Fault status 01101101
Fault priority 3
Fault frequency 1
Reset counter 76

Also it takes ages to heat up aswell and I have this fault
Address 7d Aux heat
00361 heater element for auxiliary heater z35
014 defective
Any ideas before I take it to the garage?

Thanks

Any ideas at all on these codes guys?

Thanks

Anyone with a knowledge of vcds help me out here before I melt in my car!
