2001g63

hello, recently i installed a brabus exhaust on my 2021 g63, idk if it’s me but the cylinder deactivation engages waaaay more often and even when slowing down to a stop light with my feet on the brakes, it kicks in while slowing down when i reach around 20 to 15 KMH. And also in round abouts, speed bumps and i’m not sure if the exhaust has anything to do with it or is it because of the exhaust that i notice it more often, (its really annoying with the exhaust) any one had any experience with what i’m talking about and is it normal for it to kick in allllll the time ?

Also i’ve noticed 2019/2020 g63’s cylinder deactivation system deactivates when you turn off auto start stop, on 2021 and above it stays on as long as you’re in comfort mode regardless of the auto start stop.

My cylinder deactivation stays on when my auto start stop is off.
