Abs light on constantly but no codes coming up


Registered User
I've got a Audi A3 1998, the abs light is on all the time yet when I plug in my reader no codes to do with the brakes come up, I have a speed sensor one but that is it? Also airbag light is on but nothing comes up for that either, anyone got any ideas? It's due a mot too but would it fail because of abs light or airbag light?

Whats the actual 'speed sensor' code? I assume you are using a generic reader too...

As Karl said really, get VCDS Lite and read them again... generic readers don't give enough info on VAG cars
