1.Why does the drivers door on my jaguar s type lock and then open again ? Could it be a faulty Driver door module ?

2.After spark plug replacement, there is anoise ( like a faulty bearing ) coming from the top part of the engine - only when idling ( 4,0 V8 2000 model ) only done 70000 Km.

Help me if you can, please
