Hi all - I would be grateful with any help with this recent climate control problem.
I have an Avant 2003 A6 2.5 TDI 163 Auto Sport.
It started last night during a very heavy rainfall & as I was driving through lots of puddles & surface water - which may OR may not be connected....
I first noticed the exterior temperature missing from the information system on the dash; then noticed that although the switches on the climate control unit were illuminated all the windows that have LED readouts were blank.
The readouts occassionally flashed on (the external temp display sporadically displays random temps ie -47F & then reverts to +4C & then goes off again) but it failed to stay on & eventually stayed off.
This morning after all the rain has ceased....it seemerd OK - GREAT, & was working again, on starting off - but soon started to flash on & off; and then eventually went off complertely.
Needless to say = no heating / de-misting etc.
I have a cheap vag-com cable & will try to take a reading over the weekend - although I am not sure what to look for, but in the meantime can anyone show any light on this??
I have driven in heavy rain before without any probs but can the rain get into the control unit? Does it have an ECU? Are there any known problem?
I had my previous A6 TDI for 7 years without any air-con problems....
