I've disabled KESSY already as per advice here. The one thing that doesn't seem to work is unlocking just the boot when the car is locked with the boot unlock button on the fob. Anyone else had that? Thanks.
Welcome to the Club! It does look nice in Dolphin and I was considering it but felt that the white accentuated the red details better.
As for the boot - you need to hold the button for 1+ second.
With the mk7 Golf (and earlier Golfs?) it used to be that if you unlocked the boot with the boot button on the key fob and inadvertently put the fob down in the boot and then shut the tailgate, after a few minutes the boot would lock itself, leaving the owner outside the car and the keys locked inside the car.
The mk7 did flash the indicators as a warning when the tailgate was closed before auto-locking the boot, but if the owner;
- hadn’t read the manual (many don’t) and didn’t understand the significance of the flashing indicators or
- didn’t notice the flashing indicators
they could be left stranded and locked out of their car. Inconvenient to say the least if it happens if you’re away from your home and don’t have access to the spare key fob.
I don’t know if this is still they way boot locking / unlocking works (the discussion thread over on VWROC.com at the link below suggests it was changed on the mk7.5 Golf). However, for this reason, I rarely - if ever - use the ‘boot unlock’ button, and have conditioned myself to put the key fob back in my pocket before shutting the tailgate.
I keep meaning to test on my Polo GTI+ when I’m at home so I have access to the spare key fob and don’t get locked out!
