Have tried everything to clear ABS code, guess next step is module. Trying to keep cost down, have already put more $ in to this car than I wanted. I found a used one on Ebay part # 4B0-614-517-B my part number is 4B0-614-517-H, that is number on body of unit, I actually only need the module. The seller says part number needs to be exact match, is it really that specific? Any help would be appreciated. Thank you.
