Therefore if you have a VW or Audi that was assembled from 1990 to present – you can immediately and safely use the VAGCOM-VCDS diagnostic tool.Ī car owner/mechanic can use the VCDS system for virtually all the functions that the dealer diagnostic tools can perform.īefore the owners of a vehicle had no option but to take their vehicles to a dealership to run the diagnostics… but now with VAG-COM… the smaller independent workshops, or DIY’er can perform key functions using vehicle’s onboard computer technology. VAG cars have been scannable (starting out with OBD1) since 1990’s. It also works on non-VAG vehicles, but is limited to generic OBD2 system of Engine and Transmission. Hence it’s a diagnostic software that will diagnose vehicles with VAG engines, meaning it covers nearly all Audi, Volkswagen Seat and Skoda models. And VCDS is the Windows based software that is developed by RossTech – which uses this Interface to log into car’s ECU diagnostics computer. Ok, first of all what is VAG-COM or VCDS? VAG-COM is a cable Interface that plugs into the car’s OBD port.
