Got a bit of a strange fault occurring with the central locking. It works fine using the fob to lock and unlock all the doors with no issues. However when I set off and go above a few miles an hour the doors lock themselves automatically which I assume is how they are supposed to. But then the rear and front passenger locks immediately unlock themselves and stay unlocked while the drivers side front and rear remain locked until the ignition is turned off, at which point they pop up. Sometimes while driving, the car will retry to lock the passenger side but bounces straight back up. I can't understand why the locks work perfect with the fob but bounce back on auto. Tried searching the forum and can see lots of door lock issues but none that have the same symptoms. If anyone has any ideas would be very grateful cheers 😁

Try this. Unlock the car with the fob and open just the front passenger side door. Wait thirty seconds or a minute (can't remember which it is) and see if the car re-locks itself as if you hadn't opened any doors.  Repeat with each of the other doors if no re-locking happens.

 

On ours the front passenger door opening wasn't 'seen' reliably and it turned out after a fairly in-depth look to be one of the connector solder joints inside the lock. Similar sounding symptoms to yours except I knew the autolocking wasn't enabled, and it didn't happen predictably at a given speed.  Yours may have been enabled.

 

Locking misbehaviour, another possible cause - Skoda Fabia Mk I - BRISKODA

 

Since fixing that joint (and swapping in a new microswitch while I was there, just in case) no misbehaviour has occurred.

 

 

 

 

 

 

Thanks I will give that a try. 😁
