These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

hi All, Can anyone assist please, I have just taken my airbox out to change the alternator, whilst waiting for the new one to arrive decided to give the airbox a full clean . On opening and removing the filter I saw a frame holding a sponge material which was stained and when touched fell apart. There is nothing in the parts catalogue to show a part number for this. Can anyone advise to its purpose and more importantly where I can get a replacement. Many thanks Keep safe Peter

POST 2Original post

Hi Peter New to me, perhaps someone’s attempt at doing a bit of DIY Andy

POST 3 / ORIGINAL POSTEROriginal post

Hi Andy, No its its not a DIY job its in all airboxes, underneath the main air filter. I have attached a second picture that shows the grill that holds it in place. In this case I have taken the grill out it is held in place by 6 screws, hence in my picture it is slightly out of line with the screw holes beneath

POST 5Original post
