[s-cars] ABS Off Light Problem

[Wylie Bean]

Brian
The Potomac Chesapeake Region of the ACNA has a yahoo groups email list that may be a big help locating a VAG-COM if you can't find an S-car lister locally that has one.  Don't have the web address for the group on yahoo but it should be easy to find.

Brett,

The light came on after I had the 034 brake kit installed by a local 
mechanic.  The guy's work was sloppy as hell, love the brakes though!

I don't know what ablative caps are, so I can't answer that one.  Anyone 
in MD, DC, DE, VA with a VAG-COM?

Thanks,

Brian
