ECU & TCU Reset
Hey everyone, I've been struggling with a lack of power and bad acceleration on my 2017 C300 Coupe, and until now I can't figure it out and same for the service team, every time they say that the car is pretty normal (p.s. the gearbox software is up-to-date), but it is not. Last time I went to the service for my 10k maintenance and it felt totally different for 1-2 weeks and returned back to the way it was, which means that it gets adapted to my way of driving (p.s. it's not slow at all), the gas pedal sensitivity was much better which makes the acceleration way better, so I think it has to do with the ECU (Engine Control Unit) & TCU (Transmission Control Unit) reset. I'm trying to figure out the way of resetting the ECU myself instead of going to the service team every month or so, I read somewhere that to reset the ECU you will need to unplug the negative terminal of the battery for a few minutes and plug it back and i'm not sure if that will actually reset the ECU or not. I appreciate your help because the whole thing really annoys me.
Thanks.
Thanks.

Out Of Control!!
Play service tech when the warrantee runs out, before that, back to the dealer to trade the car for one that provides drive you require---get a V12 or V8 AMG

It's more obvious while driving on Comfort mode but still Sport and Sport+ don't perform the same. That's why I wanted to reset both the ECU and TCU and see if it will make things better, but I can't find the proper way of doing that.
