Check rear earthing , I know the T5 had issues with the rear earth points literally rotting (from memory they are behind the rear lights, look for corrosion , check continuity etc)

Edit: Generally a brown wire for VW

There may be additional ones in rear quarter

Will check that out, thanks.
It didn’t do it for over a year, but now alarm goes off when parked and pings the warning when driving!!
So frustrating.

Dit you change the tailgate lock too or not? If the micro switch in the lock is faulty, you will most likely have no error codes.
Do you have a MFD where you see that the tailgate is open, on the instrument cluster?
Does the bootlight go out if you close the tailgate?

Hi
Yes the MFD shows open as the motor stops at the first position and doesn’t pull closed. Then randomly kicks in when ever.
Yes changed the lock as that’s what people said it would most probably be.
Been to three independent and the stealer. But without a code hard to find. Just seem to be throwing money at it with no solutions.

Anyone else had similar?

Anyone else had similar?

We had the same thing and it wasn't the lock at fault because I was able to isolate and test. It also wasn't the micro switch because the panel knows when it's shut, so I think it is perhaps the module which controls the lock, which I believe is behind the rear trim panel somewhere. I decided that was much to difficult to remove without damaging the many trims that need to come off. So although not the best solution, I unplugged the lock mechanism and used a wire from the cigarette light to power it manually until it was in the fully closed position. Then left it unplugged and refitted the trim over it. You can now slam the boot shut like a normal one now with no soft close and it is fully pulled in.
