To remove the speed limiter on a Mercedes-Benz, follow these steps: 1. Locate the thin lever on the left side of the steering wheel. 2. Push the lever forward (toward the front of the car) to deactivate the speed limiter. 3. Then press the lever to the right to turn off the small yellow light, which will ensure the speed limiter remains off. To enable the speed limiter function, follow these steps: 1. Press the speed limiter cruise button to activate the speed limiter cruise. 2. Push the RES/- button downward, and the set speed for the speed limiter cruise will appear in the lower left corner of the instrument cluster display. 3. If the vehicle speed is below 30km/h when setting, the initial speed limit will be set to 30km/h. 4. If the current vehicle speed exceeds 30km/h, the initial speed limit will be set to the current real-time speed. 5. Press the speed limiter cruise button again to exit the speed limiter cruise.

I just bought a Mercedes-Benz and enjoy tinkering with modifications. Removing the speed limiter mainly involves adjusting the electronic control unit (ECU), typically by connecting an OBD diagnostic tool to reprogram the ECU and modify the top speed parameter. This requires professional equipment or a visit to the dealership. I’ve tried simple software flashing myself, but the risks are high—if something goes wrong, it could cause transmission or engine failure, not to mention the legal penalties for violating regulations. In the owner groups, we often discuss the importance of safe driving speeds. Mercedes-Benz sets default speed limits to prevent speeding accidents and prolong component lifespan. If you want to attempt this, make sure to have a certified technician inspect the system to avoid hasty actions leading to additional issues. Overall, maintaining your car properly is more important than blindly chasing speed.

What are the symptoms of a faulty ignition coil?

Automobile ignition coil failure symptoms: 1. Exhaust pipe vibration: When idling, the vehicle body shakes noticeably. Observe the exhaust pipe outlet - the exhaust gas flow shows obvious intermittency with severe pipe vibration, accompanied by clear "popping" sounds; 2. Significant body vibration: During driving below 2,500 RPM, the vehicle body shakes noticeably with poor acceleration. The vibration disappears when exceeding 2,500 RPM; 3. Obvious engine vibration: When opening the hood to observe the running engine, significant shaking is visible. This vibration clearly exceeds normal engine operation parameters with substantially larger amplitude.

What Are the Reasons for a Car Engine Not Working?

Car engine not working may be due to abnormal battery voltage, carbon buildup in the throttle, spark plug failure, etc. Here is a detailed introduction about car engines: 1. Overview: The car engine is the device that provides power to the car, determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrids. 2. Others: Common gasoline and diesel engines are both reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into mechanical energy of piston movement and outputting power. Gasoline engines have high rotational speed, small mass, low noise, easy starting, and low manufacturing costs. Diesel engines have a high compression ratio, high thermal efficiency, and better fuel economy and emission performance than gasoline engines.

Will a car consume gasoline if left unused for a long time?

Yes, a car will consume gasoline even if left unused for a long time. Here are some maintenance tips for cars that are not driven frequently: 1. Brief Introduction: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 2. Purpose of Car Maintenance: The goal is to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. It is recommended to drive the car regularly, especially on highways. Mechanical components need frequent operation; otherwise, frequent stops and starts can lead to excessive carbon buildup, which significantly affects the engine. Just as humans need regular exercise to stay healthy, cars are no exception.

What Does Battery Swap Mean?

Automotive battery swap essentially refers to replacing the battery (accumulator) of a vehicle. Below is more detailed information about automotive batteries: 1. Introduction: An automotive battery, also known as an accumulator, works by converting chemical energy into electrical energy. The commonly referred-to battery is a lead-acid battery, which is primarily made of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Reasons for Battery Depletion: Frequent short-distance driving with constant stops and starts can cause the battery to remain undercharged for extended periods, shortening its lifespan. Driving at a steady speed on the highway for 20-30 minutes allows sufficient time for the battery to recharge.

What Causes Missing Numbers on the Reverse Radar Display?

Reverse radar display missing numbers may be caused by the following reasons: 1. Wiring issues: Check the connection points between the reverse radar wiring and the vehicle's installation for any loose connections, as poor contact can cause the reverse radar to intermittently function. 2. Radar sensor malfunction: Inspect the reverse radar sensors, as faults may also occur due to car washing or high-pressure water jet cleaning (also check if the internal wiring is secure). 3. Radar hardware failure: The reverse radar itself may have inherent defects or damage, or there could be loose wiring. It is recommended to visit a professional repair shop for inspection.

Can a Car Engine Get Water Inside?

Car engines can indeed get water inside. Here are detailed explanations about car engines: 1. Overview: A car engine is the device that provides power to a vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others. 2. Additional Information: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into the mechanical energy of piston movement to deliver power output. Gasoline engines feature high rotational speeds, lighter weight, lower noise levels, easier starting, and lower manufacturing costs. Diesel engines, on the other hand, have higher compression ratios, greater thermal efficiency, and better fuel economy and emission performance compared to gasoline engines.
