Ambient lighting

[alexm (Alex)]

I could not find any TSBs about the ambient lighting or active sound. However, it sounds identical to the DS 7 Issue (see below).

Issue with door lighting changing colour on its own

[Ambient Lighting] I had a problem where the polyambient lighting on my doors was changing colours 24 hours after I had set it. Some research proved it to be a widespread issue with DS 7s produced before 12/10/2018. There’s a technical service bulletin (TSB) notice out which means you can get it repaired free of charge at a main dealer. The repair involves a software update to the BSI and fitting of a new Lighting ECU calculator. TSB Notice from DS: D6AW01ATQ0.pdf (46.2 KB)

It’s likely that your BSI requires updating, so a trip to the dealership would be needed unless you have DiagBox.
