I've not had any luck yet, although the dealer still hasn't seen any manual that works yet (more to do with not having any hills round here).

I'm taking my car in on Friday, and they have arranged for me to borrow one of their manual FL2s. I'm then tasked with driving round, and trying every ramp, and hill I can find, to see if I can find one steep enough to test it on. Then report back to them, so they have somewhere to test my car.

I'll let you know how I get on

Any good news ?

Hello,
in VW new Tiguan GRC only works if seat belt is fastened.
VW fears you can use GRC brake as it was and hand brake.
