I have a 2019 C43 sedan. Was out driving last night in Sport+ and hit the accelerator hard off a light. First gear felt normal, second gear started and then for a split second it felt like no power and then it picked up again...we're talking this all happened in maybe the blink of an eye.

I can't seem to find any reason why this would happen, so I thought I'd ask here. I had a 2018 C43 sedan since Jan 2018 and just got this 2019 a few weeks ago. My 2018 did this very thing but only once and I had the JB4 installed and switched to Map 2 for the first time. Chalked it up to something to do with Map 2 requiring 94 octane gas and maybe the tank wasn't completely emptied of 91.

Thanks again everyone for any insight.

If both cars have the same problem. then I think it is something you are doing. Are you still using the JB4 with the 2019?

Thank you for the reply.

Not entirely sure what I could be doing wrong though? I owned a 2017 CLA45 for a year and 2 Audi S4's prior to the move to Mercedes and never had this issue before. Can't really mess up pushing down the gas peddle...can you?

As for the JB4...it's not installed in the 2019 yet.

I know a few people have said this, but it's doesn't feel like TC is kicking in...it happens so fast. Living in Calgary, Alberta I am very aware of TC and this doesn't feel like that.

it has happened to me under same conditions as well. No tune. I assumed I lost traction so CPU cut power.
