thanks again for the detailed response

how do you clear the code?
how do you jumper the circuit?
DIY anywhere online?

I'm pretty sure the GPs all work perfectly
PO replaced all 2x - was at the dealer 1/2 dozen time for this CEL issue
pretty sure this is a wiring 'quirk'
> I would recommend fixing the brakes however.
if the ABS lite is intermittent, doesn't that indicate another wiring
w/ VWs, unlike any other make, I generally assume the indicator faulty
rather than the part
almost always the case, IME
but maybe I'm wrong here
what would be a sign of faulty ABS?
never had it on a car b4

"coff'? typo, or something I don't know abt? oh, cough?
u mean the ABS is not working all the time and only indicator is

that's VAG-COM, right?
don't even have a PC to run it on
but it is something I'm intending to acquire down the line if I keep
this little annoying puppy
any way to check w/o V-C?
thanks again for all the help,
