2014 A7, which I believe is the same key as the A6.
The remote key still works but the little light flashes red a couple of times after activation.
Does this mean it's lost coding or battery is low?
I haven't changed or attempted to change the battery.
Thanks so much John, really appreciate the response.
It's booked in at Audi next Monday for this and a couple of other issues - I'll see what they do / say before I order up some redstuff pads.
