Power-closing door problems

[T6 - G]

Good timing, my van is going in to the VW garage on Thursday as I've still not managed to find the issue. On the invoice is there a part number listed for the item replaced? I've done a quick search, but have not been able to find the part.

Unfortunately not, as it was sorted under warranty all I got was a long waffling block of text from the tech, and now the van has been fitted out I have no way of getting to it. They just said "receiver unit" and I believe it was one of the two by the rear wheel well, not one of the units inside the door.

Hi all, just thought I'd provide my situation and solution in case it helps anyone who finds this thread in the future.

Vehicle: 2023 T6.1 with two power doors - suddenly from nowhere, driver's side sliding door would not open nor shut on the switch. VCDS showed pinch sensor was to blame, but I tested it with a meter and it wasn't the issue. (Note as well that VCDS actually reported it was the wrong door that was causing the issue so make sure you read both sides - VW confirmed this can happen in VCDS, something to do with RHD vs LHD vehicles)

The door could be "fooled" into opening by holding the dash button while turning the ignition on, this presumably worked because it was sending the "open the door" signal before it was reading the status of the pinch sensor. The inside handle would open the door sometimes, other times it wouldn't. All wiring checked, could not find anything, so returned it to VW as it was under warranty.

The issue ended up being the receiver unit in the back of the van, where there are two units above the wheel well - I think the receiver is the smaller of the two units, the larger is the motor controller which clearly worked fine.

I believe how it works is that inside the door there's a wireless sender unit (which presumably charges its battery when the door is shut) which sends the pinch sensor signal to the receiver which is over by the motor controller. The receiver had failed, so that signal wasn't getting through and so the van thought the pinch sensor was activated.

Receiver was replaced immediately from UK stock and the door has (touch wood) worked ever since.

Hope that helps somebody.

Thanks for the update, just like last year my door has behaved impeccably all summer (it did the same last year) until the first frosty morning the other day.

From looking at the wiring diagrams the smaller unit in the nearside D pillar is rear lid control unit -J605 (7H0 959243 N on mine) and the larger unit is Left sliding door control unit -J558 (7E0 959 243 D on mine). I called my local Van Centre and ordered a Sliding Door Control Unit for next day delivery (£330!!) and installed that today so will see how I get on! In an ideal world I would have swapped this from the drivers side but there is just too much in the way with the Aux Heater, seats etc.

If this doesnt work I am running short on options, I only have the door lock and motors left original now so fingers crossed!!

What fault codes are you getting? That sounds like a combination of lower battery current and stiffer mechanics/lubricant in the cold weather possibly pushing it into the current limit trip?
