Hi Folks. I own a Superb 2.0tdi DSG 2016 and have an issue with the doors locking and unlocking when I reach the 10mph auto locking speed. They go to lock and then unlock straight away. If I use the internal door lock button next to the Auto gear lever, it locks and then opens again as though the locks are bouncing. Any idea what the cause could be? Thanks.

Mine did the same after one of my door locks went faulty. Try lock the car with the remote and test each door, to see if it’s locked.

In my case, the drivers side rear was the issue.

Replacing it meant taking the door card off to get to the lock. You’ll also need a splined driver bit for the lock.

I had that problem maybe 5 years ago and it seemd to go away after I charged the battery.

Further, following a new battery about 2 years ago it has never happened again.

Worth charging your battery to see if it helps?

Thank you both for your replies. The vehicle battery is fairly new so I've kind of discounted this.

The fault has changed and now means that the drivers side rear door does not lock at all now, even though the other doors are locked, so I think as NikiB has suggested it may have a faulty door lock? NikiB, was this an fairly straight forward job once the door card is removed? Any advice regarding the steps to replace this would be greatly appreciated as I've not long bought the vehicle.

Yes, it’s not too difficult once you find the correct part number.

The lock is used across various VAG models. Mine came from a 2024 VW Taigo that had 16 miles on the clock…so virtually new and cost a fraction of the £200+ of a new one.

I followed the workshop manual which describes hot to take the door card off and also watched a YouTube vid.

There a giant plastic “bung” which you pull out to give you access to the lock from the inside. Remove that and loosen the two splined (not torx) bolts that you can see holding the lock from the outside when you open your door.

A couple of Bowden cables that you need to remove and slot back into your replacement lock.

Not too difficult, just take your time and ideally have someone to hold the door card once you’ve loosed it off just to give you a chance to unplug the speaker and window switch plugs.

That's brilliant and very detailed, Thank you.

How did you ID the correct part needed?

Sorry.......also where did you buy your repair manual from? Thank you. 😊

Think it was from a post on this forum.

It might have been this one:

A kind forum member helped me ID the correct part from my VIN…Have a look at my other post:

Many thanks for your help and advice. It's much appreciated. 🙂

Just a quick update for others with this issue. Identified the part number required for the OSR door lock (with help from a really helpful, long standing member on this forum) and fitted it this morning (Took about an hour, for me anyway!) nice, easy job and now works perfectly. Door lock part came from a 24' model Seat Arona as it'sthe same but superceeded part.

Many thanks for all your help. (What a great useful forum this is - I've been a member for some years)

Glad you got it sorted pretty quickly! 👍

My 2018 superb estate has developed exactly the same fault on the OSR door, so I will be following all these steps to rectify it. Not been here long but so far, this forum has proved invaluable.
