Yes, electronic 1x on the front axle and 1x on the rear axle, which will flag a dash warning light it triggered. VAG use 2x wires which makes a circuit - when your pads are low enough - usually 2-3mm they wear away the contact and break the circuit - which triggers the warning light.
You only have 1x indicator on 1x pad per axle - so you could have worn the other 3x pads unevenly and the 'car' would be none the wiser! - so it doesn't replace physically checking your brakes!
