Hi i have VAG-COM version 311 full version and the lead (USB to Serial) which works a treat, i was recently able to diagnose a fault with the engine speed sensor with it.

However it also picked up some errors with regards to the ABS system, i am pretty sure they are old codes that need to be cleared, so i want to clear them and run the car for a few days and then plug the lead back in and rescan for codes. My problem is that the codes will not clear using this software, i hit the clear codes button and it does nothing.

Does anyone know how i can get them to clear?

Thanks in advance for you help. Great forum this by the way!
