Volume control removal G7
the tools you will need for this;
A phillips screwdriver or 10mm socket
The first thing you need to do is open the bonnet, OK sorry about that, looking at your air box you will locate three clips holding the lid of the air box on, they are located as shown below in red. once all three are undone please move to the next step.
Take you screwdriver and undo the rubber hose connecting the air box the the throttle body and push back off the air box once undone. this will give you some room to move though very little.
If you wish to remove the whole top section then your maf sensor located near to the pipe you removed unplug this unit. taking the top off will let you have some room to do the following but not needed if you wish to try and work in a tight space.
at the back of the air box there is a rubber pipe connected, disconnect this (only vacuum) it is located near and above one of the centre clips.
once undone you should now grab the air box top half and lift the rear upwards towards you while keeping the front still in place at about 30 degrees you will be able to push the air box top back, this unit will now lift off and in place you will see you filter and your volume valve.
to remove the filter just lift there is nothing holding that in place apart from dirt and grime.
if you wish to remove the volume valve then pull out the vacuum pipe as shown, this may hiss, but don't worry its all OK! Grab the unit and just lift vertically out, thats that done.
Take the pipe you disconnected and push back into place, there is no need to worry about this being affected or the car to that point. *EDIT it has been decided that you should plug this using some top hat type plug* (courtesy of Joe and Dave)
reassemble by putting air filter in, putting top back on (don't forget that angle!) place on rear vacuum pipe, and also put all three clips back on. Push on the air pipe for the throttle body and tighten up! and then plug you maf sensor back in.
