after suffering a waterfall through the polen filter and into the passenger footwell this week(after going round a corner a bit hard) i decided enough is enough
here is a cheap easy fix to prevent future water ingress.
A Renault car (but might work on other makes as well
A spare rubber bonnet strip from the top edge from between the scuttle panel and the engine bay.
some waxoil, needs to be fairly goopy fluid, not mastic or black underseal type stuff.
and a hacksaw
Unclip the rubber guard from your car (no your not chopping this up), then undo the scuttle panel screw clips and pull up to allow access to the are under the panel.
Take the rubber strip, insert one end in under the panel, loop it and make sure the end point it on the top edge of the air intake, clip it on and work way round the edges (may need bending till the inner metal
snaps, you will feel it when it does.)
Work round to the front and back accross till you get the other end and as far as you can bend the long strip.
Try to guage how much more you need to get the strip to meet the other end.
(or you could just measure the circumference of the hole and then cut to or just over length).
Refit and work onto edge making sure it fits snuggly(adjust and cut down till it is good fit.)
Once happy with fitment remove and apply waxoil to slot in rubber strip, then refit.
The waxoil is needed to prevent capilery action from drawing water into the airvent and to prevent corrosion on the edge of the vent.
Job done, you still need to check the drainage plugs once a year or so, but the risk of wet feet is almost elliminated.
As you can see i didnt measure mine (which is why its a inch short), just wrapped it around by touch. The 5foot length of strip is a bit unweildy trying to get looped and stuffed in under there, as there isnt much room to see whilst you are up to your elbows under the scuttle panel.
Pics are of 2002 laguna II. with rubber bung culprit of wet interior hiding in the far right on the last pic.
I have enough strip left to make another one.
hmmm possible little earner on the side there
