I have an Audi s6 and am looking for help with a local user who may be able to assist. I need to run a vcds check on the car and begrudge giving the local dealer £120 for the privilege of 10 minutes of work. Basically I need to track down which module is faulty in the optical loom but need a machine to do this... Can anyone help? I'm in Dorset and happy to travel....
