Hello,
I was gifted a 2004 Beetle GLS 1.8L Turbo with a few issues. The first issue I'm trying to tackle is the ABS light is on. I've connected a code reader to it and I get the error code U0121. I was also told that a VW dealership has previously diagnosed this car with a faulty ABS control modular.
After I got the the U0121 code I disconnected the ABS from the car and ordered a replacement used part (same part numbers).........After researching the ABS system a little more I realize I should have used the VAG system to scan the car prior to disconnecting everything to help determine the long coding for the ABS.
Flash forward. I have purchased the VCDS with Hex-V2. My question is should I reinstall the old ABS (has a failure to communicate modular) to maybe get the "long code" OR would I be able to determine the long code in order to program the new ABS to work with my beetle?
Thanks
