The function restrictions error, coupled with smartphone connectivity issues, suggests a potential problem within the vehicle's communication network While incorrect pairing is a plausible cause, it is advisable to consider other factors Have you verified the compatibility of your smartphone with the Mercedes-Benz infotainment system Furthermore, has the vehicle's software been recently refreshed Outdated software can, on occasion, lead to such malfunctions It is also worth noting if other functions are affected, even subtly

Compatibility should be fine, its a fairly new phone Software refreshes thats a good question I havent checked recently But would that really kill the phone connection completely And if it was a bigger issue, wouldnt I see problems beyond just the phone Like, wouldnt the drivetrain or something else be acting weird

While it is tempting to dismiss a software refresh as the sole culprit, its influence on the vehicle's electronic systems should not be underestimated Considering the stored error message, a diagnostic scan is recommended to pinpoint the origin of the fault In my assessment, it is prudent to visit a qualified Mercedes-Benz service center They possess the requisite tools and expertise to diagnose and rectify the issue efficiently The described symptoms, while seemingly minor, can potentially cascade into more significant malfunctions if left unattended

Took your advice and went to the shop Turns out it was just a software glitch related to the phone pairing, like you suspected They re-paired everything and refreshed the software Cost me 45€, but everything is working now
