Good evening..
ive just had the same fault appear on my A4 avant 2017 model. Brake servo restricted - Stop start restricted, Audi warranty runs out in 2 weeks but as I’ve had to use my car a lot being a key worker I’ve got 4000mile
over warrant and Audi aren’t interested. So much for loyalty been with them 12 years 4 cars and nope
sorry can’t help with the warranty..
pretty annoyed with that tbh...
I’m looking online for the part to get my mechanic friend to fit and I’ve searched brake servo sensor and nothing.. is it actually called a sensor boost pressure, or is this wrong? Not paying daft prices after reading this thread the problem seems to be the sensor..
thanks
