Interior light

[markos]

Hi.I have a2005 tddi with an interior light coming on when the door is opened and going off when door is shut this will only work when the engine is running If I switch off engine light will not come on when door opened.I think this is also affecting abs light as this seems to come on and off depending if interior light is working.Any ideas ?

Have also noticed that when I open door indicator flashes once.This is doing my head in.
