The oil filter on a Mercedes-Benz E350 is housed in a plastic oil-filter housing located in the engine bay, typically on the right-hand side near the firewall, and is usually accessed from the top after removing the engine cover; some configurations may require access from underneath with the car raised.
Where to look in common E350 generations
Guidance for locating the oil filter across popular E350 models:
Model generations and engines
The E350 has used different engines over the years, but the oil-filter housing generally sits on the upper/right side of the engine. In most cases you’ll remove the engine cover to access a black plastic housing with a cap that unscrews to reveal the cartridge. Some configurations may route the housing lower or behind an undertray, requiring access from underneath.
- W212 (2010–2013/2014 facelift) and similar V6/M272/M273-era engines: The filter is inside a black plastic housing on the right side of the engine, near the firewall. Cap removal typically requires a specialized tool compatible with the housing.
- W213 (2017–present) and newer E350 variants: The oil-filter housing remains in a similar top-side location on the right side of the engine; access is usually from the top with the engine cover off, though some configurations may require slight clearance from underneath.
- Underside access: On models with a protective undertray or tight engine bay, you may need to remove the front splash shield or belly pan to access the housing from below.
Concluding: The exact position can vary by engine code and options; consult the owner’s manual or a service manual for your VIN to confirm the precise access point and remove/install steps.
How to replace the oil filter safely
Below are general steps to replace the oil filter cartridge on most E350 models. Always verify tool sizes and torque specs in your vehicle’s manual, as they can vary by year and engine code.
- Warm up the engine briefly, then park on a level surface and apply the parking brake. Place a drain pan underneath the sump to catch draining oil.
- Open the hood and remove the engine cover to expose the oil-filter housing.
- Following the manufacturer’s guidance, use the correct cap tool to loosen and remove the oil-filter housing cap. Allow oil to drain out of the housing into the pan.
- Remove the old filter cartridge from the housing. Inspect the area for sludge or debris and wipe clean as needed.
- Replace the housing cap O-ring with a fresh seal and lightly lubricate it with clean engine oil.
- Install the new oil-filter cartridge into the housing and reinstall the housing cap, tightening to the specified torque.
- Reinstall any components you removed, then refill the engine with the correct type and amount of oil as specified for your model.
- Replace the oil filler cap, start the engine, and run for a few minutes to circulate the oil. Check for leaks around the filter cap and beneath the vehicle.
- Turn off the engine, recheck the oil level with the dipstick, and add more oil if necessary. Dispose of the used oil and filter at a proper recycling facility.
Concluding: Proper disposal of used oil and the old filter is essential; always use an authorized facility and follow local environmental regulations.
Summary
In most Mercedes-Benz E350 models, the oil filter sits inside a plastic housing in the engine bay, usually on the right side near the firewall, and is accessed from the top after removing the engine cover. Some configurations may require access from underneath. For your exact year and engine code, consult the owner's manual or a service manual, and use the correct tools and torque specifications when replacing the filter. Always dispose of used oil and the filter responsibly.
