While "P061A98" can be generic, Mercedes-specific cases often point to: Sensor Failures : A dirty or faulty Mass Air Flow (MAF) Accelerator Pedal Position (APP) Throttle Actuator
In simple terms: The Engine Control Unit (ECU) has detected a conflict between the (what the accelerator pedal demands) and the actual torque (what the engine delivers, measured by sensors and calculated by the ECU). The "98" subcode typically points to a plausibility error during overrun (coasting) or idle conditions. mercedesbenz errorp061a98 top
Many independent mechanics see “torque performance” and assume the transmission is dead. In reality, less than 2% of P061A98 errors require a transmission replacement. The error is virtually always external (sensors, battery, software). While "P061A98" can be generic
