Hi All My 1998 S4 Avant (B5) keeps bringining up an airbag warning light. On VAG-COM (using 3rd party lead) it says that the fault is an intermittant high resistance on the passenger airbag module. I'm not worried about the fault, but just want the light reset. Last time Audi did it at no cost. But this time they will charge about £50 - so I bought a 3rd party ODBII lead and VAG-COM. However when I try to clear all DTCs it says that a CAN BUS is required. I am not sure if this is because the car doesnt have CAN or if it is a limitation on the 3rd party cable. I suspect it is pre-CAN. In case it makes a difference I also have the 2+2 converter lead! I have looked at the Autel VAG405 hand held unit, but don't seem to be able to find out for sure if it will reset this light - and it's quite expensive having already got VAG-COM. Any ideas or help on resetting the light would be really grateful.
