Power Tailgate Issues

[bahgoogen]

2018 Tiguan Allspace Comfortline 110TDI

As of yesterday, when the switch is pressed to open the tailgate, either on the door, inside the car or on the remote, the tailgate opens about 10-20cm and then stops. Each subsequent press, opens the tailgate a further 10-20 cm's. After 8-10 presses, it is fully open and the closing buttons do not work. The closing buttons do not work throughout any stage of this opening process.

Tailgate can be closed through forcing it down manually. Then once in the closed position, pressing the switch seems to lock it in place. Sometimes giving off 3-5 long beeps in the process.

Has anyone else had an issue like this before?

Does the tailgate have a collision sensor somewhere on it? It almost seems like it's stopping due to collision or something like that. But doesn't explain why you then cant close it also.

I'll most likely need to take it in for a warranty assessment, but wanted to see if anyone had any suggestions on here before i did that, or if i'm missing anything simple here.

Thanks!

I have no useful info for a DIY approach, sorry.

Booking it in with your dealer is the answer.
Organise a loan car Too, if you don’t have a second car.

It’ll either be a quick computer reset, or all day ‘diagnosing’ then a re-book to fit whatever part(s) they order in to replace with your part(s). Hence the alternative transport arrangement suggestion.

They don’t ‘fix’ things anymore, just replace.

Cheers and good luck.

Have you tried resetting it? Open the tailgate all the way - do it manually if required. Press and hold the ‘close’ button on the inside of the bootlid until the car beeps at you (three little chirps).

the same process can be used to program the opening height

Thanks doc_777, will give that a shot and report back.

Have you tried opening/closing the boot with your fob from a distance? If that works then you’ll have isolated the problem to the buttons themselves.

open your tailgate, manually open it fully and it should revert to operating normally. A feature that you can read in the owner's manual.

Unfortunately none of these solutions make a difference. Thank you all for the suggestions. Will report back once I take it in to have it looked at.

Doc777's solution is what it says in the manual except that it says push tailgate up by hand to full extent then hold the left button on the tailgate in until the taillights should flash and the thing will chirp to say its accepted it

Setting it like that seems to respond. Eg I hear the beeps. But the close button still does not work. Then once closing it manually then opening it again. Still only opens 20cm. Then stops. Close button still has no function.

Going to run it up to a dealer now to see if they have any clue. If not, will book it in.

WHa tif you try the right hand button Press it the light flashers and you walk away and it should close
