I had a 2009 3.0 cabriolet and used a Ross Tech cable to activate a 'horn beep' on locking the car, I've now got a 2020 Coupe TDI is it still possible to activate the 'beep'?
A quick Google tells us this is possible on a B9 chassis. You will of course need a vag aware OBD tool to enable this option. The option is most likely labelled for you.
