C87

Mine is a 66 plate, registered late 2016. Could well be a faulty batch, all appear to be failing around the same time. There is a code on the faulty part, appears to be the batch number. 1607310303111 I would guess the part was made on 31st of July 2016? Does anyone else have similar codes on their failing sensors?

I have had the exact same problem, thanks to this post I didn’t continue driving and may have  saved a costly repair to my ABS system! 
I checked the sensor data using VCDS and it showed an error on the brake booster pressure sensor. Replaced the part with a genuine part from Audi Edinburgh (£74.10) and now all is well, phew! Same part number as mentioned previously and was delivered in 2 days.

If it helps, my car is an A4 Avant Ultra 190 S-Tronic with around 80k miles.

Thanks again!
