'Brechkontakt' refers to a wire embedded in the brake pad that is designed to wear through and make contact with a metal plate when the brake pad reaches its wear limit.



Sure, here's the translation:

'Short question:'
Is the 'Brechkontakt' (presumably a specific part) only available for the Passat model?
I haven't had a close look at the contact for my Seat yet, but with the Alfa, there was only one wire going to the pad. This wire would then be worn through to the metal with use, and the light would come on.
Yes, that's correct. It only works when the label is on the writing surface, and only then does the light illuminate.

My question is related to a friend who installed contact-free brake pads in his A3 and short-circuited the contact on the connector. Unfortunately, the warning light is now constantly illuminated.
This is unlikely to be caused by a break contact, as the circuit is not interrupted.

Best regards, Jochen.

No, this applies to all VAG models. Imagine it as a wire embedded within the brake pad material. As the pad wears down over time, this wire is gradually ground away and eventually severed – this is what's known as a "break contact," because it essentially breaks.

In VAG systems, it's the opposite. By default, there is a ground connection (warning light OFF). When the contact is broken, the ground connection is lost (warning light ON).

Then he probably connected something incorrectly.
