Mass Air flow specifications
Does anyone know what the range of kg/h should be for air flow on an M274 2017 E300 4matic?
I’m getting roughly 256 kg/h and im not sure it’s supposed to be that high? I have a CEL for bank 1 being too lean. I believe the MAF is not functioning as intended

They all do that... MAF get dirty and need to get spray cleaned if so equipped.
70% chance for "no parts needed".
