how do u change on board computer BMW 525i 1990 and need a diagram of relay switches
At the bottom of the engine block.
when you turn the key in the passenger door lift the handle at the same time turn the key fully to left on a right hand drive beamer you should now be able to get in. I have a 525i and I was told by a BMW tech that even if you do not have power to open the doors you can manually use the key on the passenger side door by turning it pas the normal area it will unlock that door. I have read that the early E34 series cars have issues with the mechanisms in the doors that unlock the doors. Does this happen to all doors or just some of them?

On the top of engine in a casing in the front of the engine
It doesnt have a switch. You just open it with your hand. It does have a lock which locks it with the central locking so it should unlock when you unlock the car.
No not that i recall just it will not let you lock the doors unless you are outside the vehicle and you must use the key.
Bad hydraulic cylinders.
