This one took me a while to trace, so I thought I'd document it to maybe help others.   Fault - (2009 Fabia 1.2 Hatchback, BBM) Door open light and chime and interior lights coming on at random whilst driving and stationary. Fault was intermittent so made it harder to test.   Summary - Opening and closing each of the doors wasn't conclusive but I thought it was drivers door when I could get the fault to occur. I read up on here and then checked the wiring in A pillar bellows
