Hi fabia2312
Glad you managed to get it fixed. I had the same issue with the windows still working after the ignition was switched off. Removing the old solder (with a solder suction pump) and resoldering the LIN chip resolved this. I took a couple of attempts at resoldering the chip to get it working.
Windows still working. Hope it lasts.
Been working on a fault with the central locking on the passenger door. Door would randomly lock and unlock when driving. Also noticed that a single press of the unluck button on the remote fob would unlock the drivers door then the passenger door too about 2 seconds later. Removed the window regulator carrier, reseated the plug on the door lock mechanism and it's been fine since.
