: Many owners report this happens exactly once, about 5 minutes after a cold start, once the car begins to reach operating temperature.
In short, your Mercedes-Benz Engine Control Module (ECM) has detected that the internal data regarding engine torque—the force turning the wheels—does not match the actual, physical output of the engine, and this discrepancy is caused by excessive temperature. Symptoms of the P061A98 Code
This article provides an in-depth look at the , explaining what it means, its symptoms, common causes, and how to fix it effectively. What is Mercedes-Benz Error P061A98? mercedesbenz errorp061a98 top
Sudden spikes in the coolant temperature gauge (e.g., jumping to 120°C for a second then returning to normal).

To effectively diagnose P061A98, it helps to break the code down into its standard OBD-II and Mercedes-Benz Xentry Diagnostic System components: What is Mercedes-Benz Error P061A98
The Mercedes-Benz fault code (often abbreviated as P061A) indicates an Internal Control Module Torque Performance
Often reported in Mercedes M271 engines (like the C180), where engine overheating or incorrect temperature readings trigger torque safety limits.
The (Internal Control Module Torque Performance) indicates a fault in the engine's torque monitoring system, often triggered when the Engine Control Module (ECM) detects a discrepancy between expected and measured torque. This "top" priority error often forces the vehicle into Limp Mode —restricting power to prevent severe engine or transmission damage. Common Symptoms
While you might be able to drive a short distance, it is . The P061A98 code puts your car into a "safe mode" to prevent long-term damage, but driving with a malfunctioning torque control system can cause damage to your transmission or torque converter. It is best to have the car diagnosed by a professional immediately.
