Hello
One of the round display(where the massages are displayed) has a mark(amber colour) on it ,like it was scratched on underneath. Funny thing is that everyday gets bigger and bigger . First I noticed, I thought it is some fluff on the display,but when backlight switched off the mark disappeared.
Volvo technician said he never saw in other volvos🙄

 

I will answered myself to my post as I see on this forum ppl cant be bothered to answered
The spot seems to stop from growing, it only modified in shape and could be moisture trapped between lcd layers

I wondered if is possible to replace only the lcd itself, buying a second hand cluster of ebay(there are pretty cheap, £30)
A cluster replacement its a no, as it will have the milage from the car it came off

Some Mercedes E class have this issue ,link : https://www.slkworld.com/threads/the...thread.178242/
