So the battery after sitting for 24 hours is a bit low @12.15v and I am now wondering if it is indeed the culprit.
Mi_eg has hard wired traffic cameras that monitor 24/7 and takes snaps of folks walking past and anything else that amuses it.
It also sits in the garage most of its life and I have had a couple of instances of low battery warnings on start up.
I try to remember to leave it on trickle charge but tend to forget.
This is it's second battery and I suspect it is about 3 years old ; it is a humungous thing that requires front seat removal for access
I have finally found my Hex-net VCDS but need to buy a s/h windows laptop off marketplace to use it.
Apologies for clogging up this new age auto thread with the problems of clunky old ice's….
Thanks to
@DeKa and @ docjames for the heads up, I will report back with the solution.
