So mine has been at the dealers yesteday to fix phone disconnecting, climate sync not working & a/c no cooling.
Compressor seals replaced and re-gassed so a/c works fine, phone has been fine too so far.
Climate sync - Still does not remember to sync. It does remember if I exit/re-enter the car straight away, however I've just done a few tests and it 'forgets' to remember the sync after the doors are locked for approx. 2minutes. (the same time it takes for the interior alarm motion sensor to work)
Only difference I've noticed on screen is I now get a snowflake system near the temp setting when I first press ignition.
Software is still on 1666, 'B' device, but then I've read people have had updates and still keeping the same software number.
I'm in the car 99% of the time on my own so for me the sync not working = climate not working.
Finding this highly frustrating after coming from a MK6, A3 8p, MK7, MK7.5 all with climate control that I didn't have to sync on every journey.
