It was by pure coincidence that I was driving to someone's house yesterday to run an Obd11 scan on their car when my warning message popped up. I drove the car twice (there and back) and did around a total of 15 miles!
As soon as I got home, I ran the obd11 scan on my car and got the fault codes:
C11EC04 - Brake Booster pressure sensor faulty
U041500 - Invalid Data received from Anti-lock brake system control module
I'm not sure if the 2nd fault code is triggered due to the 1st?
I searched online and found this site and THANK GOD i did, as the results could have been extremely expensive if I assumed that it was ok to continue to drive (as per the warning info saying that I can 'continue driving').
To say i'm livid with Audi and the way they have washed there hands with the issue from other owners is an understatement! If they have received lots and lots of complaints from people with the same fault, then they really need to send out a recall notice!
Fingers-crossed I haven't bricked my abs system!
I curious to know that there is some of of 'counter' in the ABS system and if you reach 20 cycles (I think), then the ABS system bricks and you are left with a huge bill to replace.
What would constitute 1 cycle and if I replace the brake servo pressure sensor (run obd11 and clear the faults), does the counter reset to zero or permanently log the fault?
