Hey guys,

c180, w205, 2019. Love my car but the shifting has changed since a couple weeks. When i start the car it drives and shifts like it always had, but afer like 5-10 minutes of driving the car won't shift up under 2400-2500rpm in comfort mode.
This can be really annoying on the highway since it doesn't go into 9th gear until around 140km/h. Turning the engine off and on fixes this issue for another 5-10 minutes.
The only thing i tried is resetting the adaptive transmission.
Any help would be appreciated!

Isn’t the car under warranty? Aren’t you doing something that could void the warranty?

Thanks for your reply.
Sadly enough the warranty has voided since february. The only thing that happened to the car was a stage 1 tuning but that happened more than a year ago.
