Service: How to Change Engine Oil, Filter, and Air Filter

Model: Citroen C4 MK 1 - Years 2004-2010
Part: Air filter

Open the bonnet and remove the plastic engine cover. Then, using a socket spanner, unscrew the wiper arm on the driver's side. Carefully remove the plastic clips as shown in the video, move the levers that secure the plastic in front of the windscreen, and remove it.
Next, unscrew the bolt that secures the brake fluid reservoir, unscrew the bolt holding the plastic fairing shown in the video, and carefully unclip all the clips.
Proceed to remove the intake hose, then unclip the connector for the mass air sensor. The guide shows the parts disassembled so far.
Unscrew the screws holding the air filter box cover, remove the cover, and replace the old filter, ensuring the rubber gasket side faces upwards, then reassemble everything.

To replace the oil, unscrew the screws shown in the video and remove the lower protective plastic undertray. Unscrew the oil filter as shown in the video, place a container with at least a 5-litre capacity under the oil sump, and carefully unscrew the oil drain plug, allowing it to drain completely.
Now, place the new filter in the container, carefully applying the new O-ring, screw it back into place, tighten the plug under the oil sump, and pour in the new engine oil, with an approximate quantity between 3.75 and 3.85 litres. This guide was filmed on the 1.6 HDi turbo diesel engine.
