Cowling Intake Leaf Problem Solved


Cowling Intake Leaf Problem Solved

Last week we had two days of constant drizzle and just by chance I noticed that the carpet was wet under my front floor mats! obviously I panicked and started looking for the source of the water leak. After clearing the condensate drain (which did not seem to be plugged) I went online and started researching for other possible causes and found that many other Cayenne owners get water intrusion in the front foot wells due to clogged cowling drains, so i checked mine and low and behold they were clogged! These Drains are not easy to get to, one is under the drivers side cowling and is accessed either by partially removing the fender well or by removing the louvered access door where the brake reservoir is (this door is also the air intake for the A/C system) and using a straightened out plastic hanger fish around in there until you find the drain and poke thru to clean it. The other Drain is under the passenger side cowling and accessed either by partially removing the fender well or by loosening two clips, prying up the cowling and using a straightened out plastic hanger fish around in there until you find the drain and poke thru to clean it. After doing this and flushing the drains out with water multiple times I realized that this plugged drain issue is mostly caused the the large size of the holes in the louvered access door. The holes are so big that just about any leaf can fall in there and believe me getting those leafs out is a nightmare!

So after a lot of head scratching, looking at other manufactures properly designed cowl vents and cussing I came up with a solution that should take care of 95% of the drain clogging leafs, so instead of describing the rest ill post the pictures and if you have any questions just let me know.

FYI: the Strips are 1.5" wide (this fits perfectly between each rib)
