mine is going in tomorrow for a myriad of things to be looked at.
I am trying the ambient lighting thing for the second time now- mine like yours is inconsistent, console is bright, boot is bright, door trims can hardly be seen..
they initially told me it was normal- I didn't accept that, I said surely the voltage can be dialled up, they said they didn't know how to do that....If they tell me it's normal I will ask for a refund on the option as it is not delivering what they advertised it would..
I will let you all know how it goes..
