Hi All,
I have a 2012 A3 2.0 tdi, and the battery in one fob was dead. So, I have replaced it with a new CR2032 battery, and clipped it all back together.
The little red light on the fob flashes once now when you press a button.
Reading in the manual, it says to resync it you need to press the unlock button, then manually unlock the car, then hit either the close or open button.
I have done this numerous times now and no joy.
Is there anything else to try before I need to think about getting a kar key person to look at it?
Cheers
Safara
