I recently went to APR to have my Tiguan flashed... the tuner said that there is software protection on the ECU and to do the flash will need a few hours as it has to come out of the car to be done. couldn't hang round at the time so will book it in at a later date.
He said that it is about the 4th or 5th Tiguan that has had the software protection but hasn't come across any GTI's that have had the protection.
Anyone experienced this at all?
