Hi All

A bit of a minor issue but getting worse.

When driving along normally and I for example, stop at traffic lights.
As I release my brake pedal (for the car to hold on auto hold) I get a light rattle or mechanical pump knocking sound from the engine bay.
The noise is getting worse now, obviously more apparent when start-stop, as activated as the engine sound, has gone.
Any idea what this can be? I will make a booking but with the absence of technician and customer test drives its hard to explain.

Also when getting out of the car and locking the car it makes a groaning noise on a hydraulic pump somewhere?
Is this normal or common?

It's a very early build G21 320d.

Also exhibits some strange software behavior where the car on the screen in front of you when you start the car changes to another car!
