Hello!!! This is the first time around, and it seems to be an awesome webpage for M.B lovers.
I have two questions for my 1981 240D.
It won`t unlock the doors even with the engine running. You have to manually unlock each door.
And the second, It will only lock all 4 doors if the engine is running. If it`s off, it won´t lock them.
When it´s on, they all lock perfectly fine. I understand that all doors should lock and unlock with the engine on, and do the same for a while after it has been turned off. Can anyone help out here?
