Airbox (Outer part) Removal

For air filter change or manual oil dipstick access

For those that have never done this, it really is easy:

Leave the strut brace on for now, as it is something to lean on. Twist the spring loaded clips on the cover of the cabin filter so they pop up.

Lift up and slide out from under the back rubber (may need a little tug, as the rubber grips it).

Lift up and slide out the cabin filter.

This will then reveal four T30 torx head screws along the back.

Remove those (being careful not to drop the outer two down the drainage holes😛).

Unclip front of cable tray cover and remove. Pull cables out of the tray.

Lift up and pull the cabin filter housing out of the out of the way.

Remove electrical connectors from the airbox one on flap and one on the opposite side. To do this you squeeze the metal spring clip inwards and once fully pressed as far in as it will go, give a gentle tug👍.

Un-clip breather hose from the part of the airbox you are going to remove (this is just squeeze together and pull)

Now remove strut brace, as you won’t need to lean on it any more (13mm socket).

Unscrew the four T25 torx on top of the airbox.

Everything is now ready to come apart. The airbox has to be lifted up as there are location pins on the bottom.

Be careful not to scratch it on the wires at the back and also I found it easier to move the SMG reservoir out of the way (just pull upwards and tie it with string so it is out of the way and is not hanging upside down (as the lids leak🤣).

You will then see the air filter that is obvious on how to remove.

And then all will be revealed: (you can also get to the dipstick and check the oil - it requires a good tug to pop it out AND a firm push to click it back in).

Installation is just the reverse of the above.
