How to solve the Volkswagen P044100 fault code?

[SanOwen]

Solution for the Volkswagen P044100 fault code: Clean the regulating valve to prevent other issues caused by severe carbon buildup or insufficient lubrication. The function of the regulating valve is to automatically adjust the oil pressure flowing to each hydraulic system based on the vehicle's speed and the carburetor throttle opening, ensuring stable hydraulic pressure in each system and smooth operation of the signal valves. Measures to prevent the P044100 fault code: 1. Use high-quality fuel: The higher the quality of the fuel, the more fully it burns in the engine cylinders, resulting in more complete exhaust emissions; 2. Avoid excessively low engine speeds and prolonged idling: If the car is frequently driven at low speeds and often idles for extended periods, it can easily lead to severe carbon buildup issues; 3. Clean carbon deposits regularly: Clean carbon deposits every six months or approximately every 10,000 kilometers of driving. This not only reduces fuel consumption but also extends the engine's service life, ensuring smoother operation.
