Code P061A98 on a Mercedes-Benz is a complex code that requires a systematic approach. Start with the simplest solutions:

Fire up the engine from a dead cold while watching live data stream graphs of the coolant sensor. If you witness the temperature linearly climbing, suddenly jumping by 20 degrees in an instant, and then dipping back down, you are dealing with a failing electronic thermostat or a faulty sensor assembly. Recommended Solutions and Repair Costs Repair Action Difficulty Level Estimated Parts Cost (USD) $10 - $20 (Cleaner spray) Coolant Temperature Sensor Replacement Intermediate Electronic Thermostat Assembly Replacement $150 - $300 ECU Software Flashing / Resetting Professional Only $100 - $250

Locate the main engine ground straps (usually connecting the engine block to the chassis) and ensure they are clean, tight, and free of corrosion. A poor ground is a frequent and often overlooked cause of electrical gremlins.

Measure the DC link voltage at the TCU power supply pin. If the voltage fluctuates more than 2V while the engine is idling, replace the DCDC converter or 48V battery.
