There is no magical reset button. Here are your three real-world solutions, ranked from cheapest to most expensive.

Mercedes uses torque monitoring as a security feature (Anti-Tampering) and a reliability feature. The ECM calculates torque based on:
While the code says "internal," wildly implausible signals from the Throttle Body , Mass Air Flow (MAF) sensor , or Accelerator Pedal Position Sensor can sometimes confuse the torque calculation logic to the point where the ECU flags an internal error.
If the discrepancy between these two values is too high (typically more than 50 Newton-meters for over a second), the car triggers the fault to prevent engine damage. The "98" Sub-code:
