[s-cars] ABS Off Light Problem - VAG COM

I had mentioned in the fine print that some S4 owners were having  
scanning the ABS module.   I guess we need an affirmation from at  
least one
that they can scan the module.

I believe Ian has the Airbag control module mixed up with the ABS.   
The airbag
controller and connectors for early models are indeed in the center  
console.  The
ABS electronic controller is under the rear seat, drivers side.  I  
know of no direct
reading connectors for VAG-COM, though.  The fault codes are stored in  
the ECU.

It could be that the fault has been corrected but the fault remains  
until cleared in
the ECU.  Try clearing all the codes and perhaps the light will clear
