Hey everyone, new to Mercedes just bought myself a 2015 c250, 160xxxkm. I am very unsure on what’s normal and what isn’t. I currently have 2 problems.
1. Once driving and stopping I always hear a buzz buzz buzz sound in the centre iPad thingo. Not sure if normal but happens sometime when driving, and once turn on and off. I would be aware and ok if it was just when it turns on and off due to it setting up or whatever but unsure why it sometimes happens when driving.

2. my panoramic sunroof shade opens alright but doesn’t close. I have to try multiple times to try close it. Also the sunroof never can manage to open. It’s as if it stalls or something. I press open button and it goes up about 2-5cm and closes right back down. Could be a warning I need to do something. Could be it needs fixing.

just wanting to see what u can do for both and if I need to take to a shop. Don’t want to spend a lot.

cheers everyone, can send videos if need be.
