Q: How often should a Mercedes fuel filter be changed?

Mercedes-Benz Fuel Filter Replacement Guide‌

‌General Recommendation‌
For external fuel filters, replace them every ‌50,000 km‌—they’re easy to access. Built-in filters last longer, over ‌100,000 km‌, but need more work to replace. If you use good fuel and drive in clean areas, you can extend this slightly, but don’t go over ‌80,000 km‌ for internal or ‌30,000 km‌ for external filters.

‌Influencing Factors‌
Adjust the cycle based on how you drive. If you often use low-quality fuel, shorten it by ‌30%‌. Driving in dusty areas or making frequent short trips can clog the filter—check it every ‌10,000 km‌.

‌Inspection & Verification‌
After replacing, do a fuel pressure test. Normal pressure should be between ‌250–350 kPa‌ to ensure everything works right.

Q: How much does it cost to replace a fuel filter on a Mercedes Benz?

The cost of replacing a Mercedes Benz fuel filter varies depending on the vehicle model, filter type (such as internal or external), and repair location. Taking the Mercedes Benz C-Class as an example, the original fuel filter price is about $510, the labor cost is about $110, and the total cost is about $620.

Cost influencing factors: Cost fluctuations are mainly affected by the following factors:

• Model differences: High end or built-in filters (requiring disassembly of the fuel tank) are more complex and costly to replace, for example, the cost of built-in filters may be around $42-139, while external filters are relatively cheaper, around $14-42.
• Repair location: 4S stores usually charge higher fees due to labor costs and service standards, around $69-139, while regular repair shops or auto parts stores may charge as low as $28-69, but the quality of original parts is more guaranteed.
• Accessory selection: The price of original parts is stable, but disassembled parts or aftermarket parts may be cheaper (such as disassembled parts costing about $28-42, but the quality and lifespan may be questionable).

Overall, the replacement cost is roughly in the range of $28-139, depending on the vehicle model and repair plan.

Q: Where is the fuel filter on a Mercedes?

The position of the fuel filter in Mercedes varies depending on the model and year, and the common installation methods are internal and external. The built-in type is usually integrated with the gasoline pump in the fuel tank, while the external type is mostly located at the oil pipe connection of the vehicle chassis or near the engine compartment.

Search method: Track upstream (towards the fuel tank) along the fuel supply pipeline of the fuel injector. If a component similar to a metal can is visible on the pipeline, it is an external filter; If no external components are found, the filter is likely to be built into the fuel tank. For external type, after lifting the vehicle, observe the connection of the chassis oil pipe to locate it; For the built-in type, it needs to be indirectly confirmed through the pipeline interface near the fuel tank.

Attention: Some diesel models may have fuel filters located directly in front of the fuel tank, and the filters are usually marked with installation direction signs (such as arrows or IN/OUT letters). When installing, ensure that the direction is correct. Due to the diverse range of Mercedes models, it is recommended to conduct precise searches by combining specific vehicle maintenance manuals or professional diagnostic tools.
