Hi, for the last few months I’ve noticed that the sunroof open / close speed is a crawl when engine is switched off, and I’ve started getting random errors such as ‘Intelligent Lighting System Inoperative’, and ‘360 Camera Not Available’ sometimes when starting from cold. Would this be the battery? If So, is it the aux battery in the boot I need to replace? My vehicle is an E250 Petrol 2013 year. Thanks for any help.
