What are the odds that the 2012 model allows you the option of disabling the anti-theft alarm confirmation beep? I'd trade up to a 2012 for that feature alone.
You're right, the dealer should be able to do it. However, when I took my TDI in for its 10K service, the dealer said "no-can-do."I think that this can be changed using VAG-COM? The dealer should also be able to do it, but I think that they'll charge you for 1 hour of labor for a 5 minute job?
