4. If I buy the KVW100 but update failed how should I do?
Do not attempt to do it again. First to check you comfort module to insure that comfort module is fine. Then check the KVW100 whether it has been plugged in tightly and if you have followed the instructions correctly.
If you have any problems you can use a VAG-COM cable to check whether you can enter the 46 module. If all of these are ok it maybe your vehicle is unable to be updated or possibly you may have done something wrong. Please feel free to contact us or our local dealers directly to rectify your
problem.
