I'm sorry, but that's really funny to me - not because I'm laughing at your misfortunes of course, but because of how easily people forget history or are simply unaware of it.

Media systems locking due to the lack of power is not a new problem. I do remember having the exact same problem on my 1994 Passat, where the radio would lock itself and you had to go to the dealer to have it unlocked.

>>And we do not have the pin, we were never given a pin

Literally the same problem, except 25 years later :P Manufacturers almost never issued these special pins to unlock radios.

And like, disconnecting the battery has always been a problem in cars, BMWs, Mercs, Opels, Peugeots, Fiats - I've had them all and they all did something weird if you disconnected the battery - more often than not, a check engine light would pop up and you had to bring it to the dealer to clear it. This is not new.

We were not aware of that and that was definitely a new experience for us. My father owns a car bought a decade ago and we can easily fix and swap any parts we wish without having to worry about getting sign-off from the car "owners" :D I don't see why that would happen, and seeing that as a common practice among other car manufacturers does not make it any less annoying.
