With the new O rings in place, the new element can be slid up the shaft into position. I then re-installed the new filter assembly into the canister and tightened it to 25nm.

Next I removed the sump drain plug under the engine. This has to be done carefully to catch all the oil that will gush out once the plug is totally out. It is possible to almost remove the plug and allow the oil to flow slowly at first.. I had allowed the oil to mostly cool from an earlier run, as I did not want to get my fingers in hot oil.

No pictures here as I could not get the camera into position.

I used a bucket large enough to hold 8 litres to catch the old engine oil, and this took about 15 minutes to completely drain. 8 litres of oil will fill a bucket like the one shown below.

Next I fitted a new crush washer and re-installed the sump plug. I then re-fitted the 2 splash panels in the reverse order to the removal. A little grease on the screws also seemed a good idea.

I then added 7.5 litres of new oil via the oil filler hole, using a tapered funnel and rags to prevent spillage.

I removed the car from the ramps and ran the engine for 5 minutes. I then switched off and allowed the car to stand on the level for another 5 minutes. I checked the status of the oil level via the engine management system, and added the remaining oil until it reported OK. I double-checked using an MB measuring stick (no dipstick on my model) and the level was also OK.

I cleaned up, reset the service interval on the cluster, and the job was done.
