Hi all, I have a question about ambient lighting. The rear passenger side door ambient light strip is acting strange works sometimes or changes it’s own colour? Anyone had this or any advice on what causes it and or sorting it out please. 
cheers for any help cus it’s annoying me. 

Could be the bcm on its way out. Mine just stopped working along with dash lights and stereo lights. Also heated seats stopped. It’s called the comfort control module. 400 quid part then some hours to fit and recode 

Wow thanks for reply doesn’t show up on a fault reader though??
