When my car had been parked for a few days, suddenly found all the car windows open. The doors were still locked & the windows were definitely closed an hour before. I do not understand

how it is possible. Windows closed ok & everything seems alright.  Does anybody have an clues what may have occurred, just imagine if I had been parked in a car park & the windows

opened themselves.

Thanks for any help.   

You might have had the 'open' button on the key depressed by accident, in a pocket etc. - this will open all windows.

Could also have a faulty BCM.

Keep an eye on it, and be careful of the keys as said! As it'll lock itself again if no doors are opened.

Most likely inadvertent hold of open button with keys in a pocket. Its happened to me a number of times on various VAG cars ive owned.

Ive never personally found much use for comfort opening so I now take to disabling it in the infotainment. The only drawback is that comfort closing (which is IMHO more useful) also gets disabled.

If you google around, you should find it's a fault that can occur with several makes, VW brand, BMW, Vauxhall to name a few. Went to our Seat one morning to find both back windows down. Took several attempts to get them to stay closed. It was used but recently bought from a main dealer. They reset the system, and so far OK.

Once driving a mk2 Octy on a motorway, all the windows dropped. But only the once.

My last O2 did this quite often towards the end, something wrong in the comfort chip I was told, then we couldn't reset the airbag warning light either which became an MOT failure.

 

I'd get youur car into the dealers if I was you.

Thanks everybody, it must have been keys in my pocket, now disabled function so should be ok.

I suggest calling in a priest 

It happened mine a few weeks back. I am pretty sure I didnt press keyfob. I disabled the feature via radio just in case.

Convenience module?

If you keep your finger on the locking button a bit to long,a lot of skodas will drop the windows a few inches,keep your finger on it to see if that happens,as has been stated you can have it tuned out,or just give it a short press to lock.

Mine were fully open, front & rear. It was a very frosty morning....dash & seats were covered...so windows must have been down all night

O3 doesn't have a convenience module, it has a BCM

Seems maybe yours is not the only one.... http://www.pistonheads.com/gassing/topic.asp?h=0&f=86&t=1472984&i=999999&nmt=2013%20Leon%20windows%20opening%20when%20locked.

My car unlocked itself the other night. More faults to add to the list.

Excellent - thats a new one!

At least my windows stayed up!

I don't know how the OP coped...
