The oil filter on a C280 Mercedes 4matic 2007 is located on the bottom of the engine, next to the oil pan. It is a cylindrical-shaped object with a black cap. To access the oil filter, you will need to raise the vehicle or crawl underneath it.
Once you have located the oil filter, you will need to remove it. To do this, you will need an oil filter wrench. Place the oil filter wrench around the oil filter and turn it counterclockwise until it comes loose. Be careful not to spill any oil.
Once the oil filter is removed, you will need to install a new one. To do this, apply a thin coat of oil to the gasket of the new oil filter and screw it on until it is hand-tight. Then, use the oil filter wrench to tighten the oil filter until it is snug.
Once the new oil filter is installed, you can lower the vehicle or crawl out from underneath it.
