I have a 2015 S550, and am having a difficult time filling the gas tank. I need to hold the nozzle at a 90 degree to the left angle in order for it to fill without triggering the full tank stop from the pump. Anty other way and it thinks the tank is full. It is really annoying. Anyone else experienced something like this, and if so, any suggestions? Thanks.

I had the same issue on my 2015 S550 in 2017 and it required several MB service visits to correct the issue. Ultimately, the dealer replaced the fuel charcoal canister and shut-off valve and then updated the engine control module to the most current software. An annoying problem fixed under warranty.
Factory warranty covers canister & valve for 3 years/50,000 miles (whichever comes first). Engine control module is covered for 8 years/80,000 miles so software check/update should be free, have MB dealer pull fault codes & check/update ECM software. DIY or independent canister/valve replacement if need be. Start here to comparison shop part costs: https://www.mercedespartscenter.com/
