Plenum Check - The Reason Why **ALL OWNERS PLEASE NOTE**

john adam · 25th July 2023, 05:45

I have the dreaded sunroof drain problem on the driver's side. I did the passenger side 3 years ago following Artic's excellent articles. Wasn't too bad a job. Just wondering if Artic has done the drivers side. It is a real pig, can't see the outlet, it is hidden behind the wiring loom and a few electrical items. I may be able to locate it by feel enough to enable me to push in the plastic connector.

Hi John.
This should help somewhat, but sorry some photos are missing but there are enough to get the job done.

Hi members / owners we are moving into the wet weather section of our year from now onwards up to April, so lots of rain coming our way from to then, those plenums will need to be checked at least once every week, it's not an hard job and could save your car from expensive damage.

As a new owner, this is great info, coupled with useful pictures will make the task much easier. Thanks Arctic.

Just realised my car is missing the panel under the meshed cover so the plenum is just open to the elements.

Are there closure panels for each side, or are they just fitted on the pollen filter side?

Pollen filter side only.

Now to put the cat amongst the pigeons

I do not have the "spy hole" and have in 21 years of ownership not needed one.

The secret? Jules' plastic insert on the drivers side of the plenum AND blocks of large pore acquarium filter material on each end, blocking any access to the plenum chamber. Very minor debris through the plenum chamber covers.

Although I am surrounded by many trees including Scots Pines with their needles especially at this time of year, an annual vacuum cleaner suck is all I have ever done.

Many years ago on Trikey's advice I fitted aquarium filter material and have never had problems since
