I had noticed on my V40 that on occasion the driver's door wouldn't open at the end of a journey until I had unlocked all doors, so I decided to experiment.
At the end of a journey a few days ago I stopped and turned engine off. Then I pulled the door handle towards me, and unlocked then locked the doors. At that point I was deadlocked in on the driver's side.
I unlocked all the doors, but couldn't get the driver's door to open. No matter what I did, I was locked in. The other doors could open OK. I restarted the engine, unlocked again, even opened the window but the door couldn't be opened from outside either!
I played with all the settings in My Car regarding security and arming the door locks and alarm, to no avail.
I ended up getting out the passenger door.
The next day the doors were back to normal and since then my door opens even if the rest are locked, but what happened was strange. Can someone else try the above to see if it's a generic problem or just something I need to get looked at?
