Step 4

Now we need to drain the oil. Using a socket set or breaker bar, gently loosen the sump bolt.

Step 5

Prepare your oil pan and loosen off the sump bolt by hand.

The oil will now drain into the pan. Once the dripping has stopped re-install the new sump plug and washer. You can re-use the existing bolt and washer however this is not recommended as leaks can occur.

Step 6

Locate the oil filter in the engine bay. It is a cartridge style filter inside a plastic canister.

Step 15

Now fill the vehicle with 5.5L of oil. For the Australian climate we chose to use fully synthetic 5w-40.

Step 16

Before starting the engine we need to check the oil level. See our guide on accessing the Engineering Menu.

Once the level is at roughly 5.5L start the engine and monitor for leaks. Turn the engine off and re-install both splash shields. The oil level will drop after you have started the engine.

    I live in the Caribbean and have a W203 C180 Kompressor it is normally serviced by a MB Technician.
    Is it the same process as shown above; I would like to change oil and filter for myself.
