Hi new to this forum, sorry if this has been covered before as there are so many posts about this issue,
I had the dreaded stop start and restricted braking, on my Audi A4 ultra 2016 a couple of days ago, it had been standing for a few weeks.
I didn’t drive anywhere, obviously I wanted to get the issue diagnosed.
after reading a few of the earlier post about Abs issues,I’m so glad I didn’t drive it.
So I Plugged her in with Vcds , I got errors pressure brake sensor fault and the abs module implausible error.
so after reading all the earlier post, I needed to get in touch with Audi, so I could get the offending part replaced! with me being out of warranty by a month
I didn’t have much choice but try change the boost sensor 5Q0 906 207.
Audi parts guy said that part has been superseded by 5Q0 906. 207 B
so that was purchased this morning for £79.90, I fitted in probably 5 mins.
all is good so far.
So obviously Audi have realised there is a big issue across the Audi range with the old type part.
So guys get it changed for the new upgraded parts to save any future issues.
