I have an '01 (new shape) A4 and just recently the Climate Control's
ECON switch remains illuminated after I switch it off. I don't really
care about the light - what I care about is that I can no longer switch
on Air Conditioning!
Does anyone know what might be causing this? Is it just a simple case
of regassing the Air Con?
I have checked the newsgroup for similar postings and found some info
(by Ronny) on accessing the climatic diagnostic controls for a 97 model
which, I will try later.
There was also another thread where the author (MATT WILLIAMS) had the
swith and software replaced and various other parts replaced - which is
very concerning - I've only had the car since the begining of January!!
