Hi everyone,

I've searched the forum and found several similar tailgate problems, but I haven't been able to find a solution that exactly matches my case. If this has already been discussed or solved elsewhere, my apologies, and I'd really appreciate a link to the relevant thread.

I preferred to start a new topic rather than resurrect an old one because my symptoms are slightly different. However, I've read the previous cases and will test the suggested solutions, particularly the latch/closing-assist mechanism, and report the results here.

Car: Skoda Superb III, 2017, 3V3 Liftback (not Estate/Combi), 1.4 TSI 150 PS, DSG7 automatic.

Main problem

• Pressing the opening button operates the latch, but the tailgate does not lift by itself.

• If I give it a small manual push, the electric drive starts working, raises it to approximately 1/4 of its travel and stops.

• Normally it will not power-close either. Pressing the button only produces the "beep beep" warning.

• The interesting part is that when the car correctly detects the boot as open and the open-tailgate symbol appears on the instrument cluster, the tailgate can sometimes continue electrically all the way to fully open.

• If it reaches fully open, it can sometimes power-close normally as well.

Because of this, we're particularly interested in the latch/closing-assist mechanism and the signals used by 6D to determine whether the tailgate is open or closed.

VCDS findings so far

Both position sensors track each other extremely closely. For example, at approximately 24% opening:

• Position Sensor 1: 512

• Position Sensor 2: 511

• Rear lid position: 24%

When completely closed, both sensors return to 0.

After clearing the previous faults and reproducing the problem, 6D currently stores no new DTC.

I have also tried:

• Rear lid: reset standardization

• Adapt flap opening angle

Both Basic Settings start but remain indefinitely on Running and never complete.

6D controller

• SW: 5Q0 959 107 L

• HW: 5Q0 959 107 J

• Component: HDSG-Modul H13 0261

• Coding: 1008

• ASAM: EV_DeckLidCONTIAU736 001014

I'm using VCDS 21.9.0 x64 with an AliExpress interface which cannot be updated, so I'm also keeping in mind the possibility of a limitation with this VCDS/interface setup.

What I'm looking for

Apart from ideas about the fault itself, I'm particularly looking for data from a known-good Superb Mk3 3V3 Liftback (not Estate):

• complete 6D Controller Map,

• 6D Adaptation Map / ADP map,

• 6D coding/configuration,

• and, if possible, measuring values related to the latch/closing assist and reasons for cancellation/stopping of tailgate movement.

Ideally from the same or a very similar module:

• 5Q0 959 107 L

• HW: 5Q0 959 107 J

• HDSG-Modul H13 0261

• EV_DeckLidCONTIAU736 001014

• Coding: 1008

I don't want to run Resetting all adaptations until I have backed up my current configuration and, preferably, have a known-good configuration for comparison.

If anyone has a 3V3 Liftback with an electric tailgate and VCDS, or has experienced similar symptoms, any information would be greatly appreciated.

I'll update the thread with the results of further tests and, of course, the solution if we manage to find the cause.

Thanks!
