Hello everyone.

I've just picked up a 2013 Mk2 Superb Estate with the electronic tailgate. It opens with both the keyfob button and the tailgate handle button, but if I press the release button next to the DSG selector, nothing happens - no warning sounds, nothing on the Maxidot either. The other two buttons in this area (traction control off and tyre pressure) both work okay. All three switches illuminate in the dark.

I have made sure that it's in park with the handbrake on, and I've even tried with all the doors unlocked, I've tried pushing once, holding the button down, etc.

Any thoughts?

Added new check.

Update

I've replaced the switch (part number 3T0959831 if anyone's interested) but still no change. That bit of the loom looks to be in good condition as well, and it still illuminates.

Can anyone suggest some sort of diagnostics I can do besides a multimeter on the plug? Also, is there a chance this could be coded not to work?

Had five minutes today so plugged in the VCDS. No fault codes on the electric trunk module. Went in to try the function tests, and when I tried to run the test to open rear lid, I got the error "refused by control module" with the code 7F 2F 22.

Edited error code.

I've found the broken signal wire from the door module (as well as a couple of others) in the driver's door bellows/gaiter. New pre-wired 28-pin connector ordered, and will redo all the wires into the door...
