P02FF - fault code on GLB250
Hi folks - anyone come across this fault code P02FF? I have a 2021 GLB250 with 7K KM. Just got the first oil change last week. We drive the car everyday - turned it on today and pulled this code. I've googled it but there's next to nothing on this one code. I'll got to the dealership but just wondering if anyone has any experience with this one? Someone also had it on their GLE, and the code is named "Propulsion System Inactive Timer Performance"
I'll say this - my engine makes that high pitched knocking sound...really annoying. I hope it's not related to that.

I found below for P02FF (Fuel and air metering common error code) and P261029/P02FF85/P02FF02, so you should go to a dealer:

What was the problem/fix? I too have a 2021 GLB 250 with low miles that this popped up. No odd noises or other messages. Just had a check engine like and then I pulled this code when checking, PPO2FF
