That would depend on what diagnostic tool you have. Most scanners will read and clear codes. The VW's need a vag-com cable from Ross Tech and software on a lap top computer to access the ECU and change parameters.

Head over to a VW forem. They should be able to tell you if your tool works on the VW computer system. They can go into much more detail than you are going to find here. Good luck and when you find what's going on, update this question so others can gain from your experience. http://forums.vwvortex.com -- http://www.vwforum.com

No you need to use vagcom or vag commander in order to change parameters, but I doubt your computer needs a reflash.

All mark IV VWs throw random codes if the have been modified with anything that messes with their fuel/air mix. Cold air intake, new exhaust, reflashed ecu, downpipe...post your codes on vortex and people will help you out or swing by autozone and they will give you a list of all the codes with a listing of "probable causes". Best bet is if the car runs well, leave it be and just keep up with the regular maintenance.

It should do so long as the issues you fixed are actually the problems the car is having. If the previous owner "chipped" the car, replacing the stock ecu with a newly programmed chip, you may end up just living with the light being on. What did you fix? It may give us a better idea of what the car is doing.
