Six Foot OBD II Extension Cable
Audi C5 A6 Quattro 4.2 

This ECS OBD II 6 foot extension cable allows you to place your connection out of the way of your legs on the driver's side of the car. This extension cable is 6 foot so it allows you to place your connection/laptop on the passenger side if necessary.

Also this ECS OBD II extension has a 90 degree fitting so it's as flush as possible in the driver's side foot area.
