I have owned my 2019 E63S Wagon for about a year and a half. Race Start has always been a blast, and I know how to use it, but recently it quit working. No matter what combination of Sport, Sport+, Race, engine and transmission temps (Yes, they are always above the blue zone.), and break pedal force I use, it just always says race start not available.

Its worth noting, I just had the transmission valve body replaced under warranty, but it wasnt working most of the time before that. I plan on pushing on the dealership to figure it out, but I wanted to know if anyone knows a way to see the computer conditions to find out which one is keeping Race Start from activating. Does it require some tuner level of computer access to see why it wont allow race start?

Thanks!
