[joolsik]

Hi mates,

can someone give me some advice how to repair Audi TT MM Dashboard 8N1919860C? It's working fine when the temperature is normal, but when it is very cold the dash is dead. I've tried to check and repair soldering, but not much success till now. Can someone give me some clues?

Thank you very much
Regards
