    Mine still leaks with the original fix but I cant figure which hole its coming through. Although the panel is sealed well I think the foam/rubber still lets water penetrate so the problem is still present just not as bad. Ive taken the sound proofing off for now and I have an engine cover to stop it going on the engine.

    Just get a can of expanding foam, stick the nozzle in by the wipers and pull the trigger till its full.

    Trim away any excess :D

    That's probably not a bad shout! Who's going to be brave enough to give it the first go!

    I dont think my suggestion is a goer really :) having used expanding foam i wouldnt want that stuff anywhere near my car lol.

    However i thought it was a fairly water resistant once set.

    Under warranty till Aug 8th so free until then.It had the thicker seal put on and new clips.
    Will do it myself and probably use some Wurth removable sealer(doesnt go fully off) we have at work.No point using sikaflex or similar as it will be a pain in the ass if you ever need to remove the trim.

    I recently discovered mine was leaking aswell so I just ran a small beading of clear silicone between the gap where the scuttle meets the bonnet, seems to be keeping the rain out so far after some heavy downpours.

    I've just taken my scuttle off and I've silicone every hole I could find, then I put a bit more silicone in the hole then slapped a lot more in

    I'll let you know if I get leaks

    Let us know. Has anyone just put black silicon or sealant around the curve part of the panel and seen if that stops water from getting through?

    I'm going to be doing that in next few dats, I'm a bus driver, when a window needs sealing the engineer uses this hard wearing stuff to seal it. Its black but once its on it doesn't come off

    Gonna check my coil packs and plugs at the weekend. Wouldn't it be better to have a mouldy damp bonnet lining instead of water gathering in the coil packs? Going to have to look for a engine cover to butcher around my intake I think as I never thought about the potential for the plugs and stuff getting wet.

    Without a lining and the 2 holes partially behind the diagonal parts being plugged, water can come down inside the strut and come out in the same area as the filter.
    The centre hole and unsealed clips is where it intrudes onto the engine.
    Maybe just a freaky coincidence with the angle I was parked but definite drops of water on the foam a while back.

    Since sealing mine using a 3m D-shape seal along the back of the strip and a solid ribbed rubber block along the bonnet recess to marry up - guess what....the water still collects!
    But using the clips with seals, having the 3 holes plugged and lifting the bonnet just above the horizontal to let any water run away harmlessly down the windscreen means the engine seems to be staying relatively dry.

    Is there no way of having small rubber hoses attached to the drain holes that are needed and have them routed into a low part of the engine bay so it gets rid of standing water and the water then doesn't touch the bonnet liner. Just thinking so i don't have a plan on how to do it.

    This is exactly what's happening to mine now, rained last night. I put a towel over the engine cover and revo intake just incase it happens and it did. The towel was soaking were the filter was.


    So now I need to fund out were the waters coming from. I've plugged every bloody hole. So ill have to check the struts when its light.


    Still don't see how the water can be getting in even from struts. and the binnent was bone dry underneath, I've left it with no sound deadening

    Its these, there is a pic on the first post:
    [​IMG]

    Without those, each hole will happily allow water to leak into the engine bay once the water comes up to the height of the turret they locate into. Obviously if you have the other drain holes blocked up properly, these are the only other holes it can be leaking through.

    Additionally, I found I had to tease the expanding plastic clips out a bit with a little screwdriver to make the seal tighter. Just pushing from above and letting the plastic tabs naturally clip out and grip was not enough to assure it was water tight.

    The only problem is that to 2 clips you really need to make sure are fully pulling the strip tight are hidden under the struts, and these are the 2 which (if not water tight) will allow water to travel down to the filter area.

    As above, the 2 which allow the water to travel down the strut are the 2 which are hidden behind it. Apart from pushing down firmly from above, there is no way to gently pull out the plastic clips to assure its super water tight.
