[A4] Question 2, ABS Rebuilders...

[Peter Kirby]

What were the symptoms of ABS failure:

ABS light on?
ABS pulsation at low speed?
Getting disconnected from ECU when using VAG-COM?

I'm asking because on my car the ABS pulsates at very low speed when
braking yet the ABS light does not come on.  If I connect VAG-COM to
look at brake functions, everything is fine for a while and then I get
disconnected.  My mechanic immediately said it was the ECU but then we
did the same test on a A4 with working ABS and it also would
disconnect from the VAG-COM (albeit at higher speeds).

Thanks.
