Hmm, don't know what to do. If there is a VW update I feel the car should get it because, correct me if I'm wrong, it doesn't just update the engine ECU, it also updates the cars 'operating system', i.e all the controllers for the windows, locks, and all the other modules which you see on VAG-COM.
It will be a pain in the ass if they wipe the remap though as it'll mean setting a day aside and making an appointment to go and get it re-Revo'd.
