Having purchased my MY2008 Audi TT convertible, and immediately changed the oil and got a new MOT, the “Service Due” light came on. No problem I thought, just some routine fiddling about with the odometer knobs and all will be well. Not so. Audi lock this right down and workshop ready scan tools are required. With an Audi cabriolet also in the stable, finally bit the bullet and bought myself VCDS and cable from ilexa.
