Can anyone help?
I've just purchased a 2007 380 sx/db series 3 which I'm very happy with. However, the interior lights don't come on when you open a door.
The lights work manually from the manual switches.
They won't however turn on the interior lights.
All fuses are OK.
Any ideas?

The lights work manually from the manual switches.

^^ confuses me.

Do the lights turn on if you unlock the car? Sounds like a switch issue, but would have no idea where it'd be regarding interior lighting.

Hi mate and welcome

Only thing i can think of is I'd say someone has messed with the settings on the center display. You'll have to go into the multi function display above your hazard light switch. Press Disp. Select Customization. Select lights. And then select dome light shutoff time and then make your prefered choice for lighting.

There is a detailed explanation and how-to on chapter 3 of the users manual. See Multi Center Display.

Hope that helps.
