Trying to enable tourist mode for driving on the continent. When I select channel 2 I get an error message that a security access code is required. I enter it and it's accepted but I still get the error message that the security access code is required. I'm using 15284 as per VW Golf (1K) Headlight Aim Control (Xenon with AFS - Ross-Tech Wiki) and it's acknowledged as correct. Should I be using a different code?
