Haha, thank you for sharing! I had that moment as well, at my previous job I have changed a Mercedes oil at the shop one day, and I had the same problem. Turns out it's all electronic. Some of the dipsticks on mercedes are at the very back tucked in on the drivers side of the engine. It's kind of odd..I much rather prefer the dipstick, it makes way more sense! I'm glad to see you are enjoying the series!
