    Having read a few of these threads about scuttle leaks, none of them really say how to get the scuttle off so i thought i would add my experience from today. I wasnt planning on doing a guide so i havent taken photos of every stage but perhaps this may help someone anyway.

    My sound proofing was absolutely soaked and weighed about a stone so was sagging in the middle, luckily it hadnt gone mouldy yet so i took it out and dried it out in the boiler cupboard for about a week.
    Now it is dry i have painted the back with isoflex liquid rubber £12 from b&q, its a cheaper version of plastidip already mentioned by others and is alot easier to get hold of. This provides a coating that should stop water being absorbed or at least minimize it.

    Just a note if you do this, make sure its well ventilated as it is really strong smelling and takes days to dissipate.

    Having opened the bonnet and removed your soundproofing by squeezing the black clips together you will see about 10 star bolts at the base of the bonnet these hold the washer jet side of the scuttle. Above these you will see plastic clips that stick through. You can only see 7 however there are 9. The clips at each edge of the bonnet are concealed which is really poor design by seat and makes life very difficult. You have to squeeze the 7 clips with pliers and push and they will pop through the hole.

    On the left of the bonnet the washer pipe goes through the scuttle so the rubber around it needs to be pulled out to allow for movement.

    Having done this pull the scuttle away from the bonnet on the outside. Once there is enough room you have to try and get to the 2 edge clips that you couldnt see underneath. I had to use a bit of force and a screwdriver etc, unfortunately after much perseverance i actually had to break them.

    Now unclipped you have to drop the scuttle down about an inch as there is a lip at each edge holding it to the bonnet. You should now have enough space to unclip the washer piping from the back of the scuttle.

    The scuttle should now be loose but the washer jets themselves need to be removed, do this by squeezing the lever clips on each side and pulling them out.

    Now the scuttle will be free.

    As you can see my panel is the newer style with the reinforced back. My car is an 07 plate ref sport.
    [​IMG]

    To fix my leak i planned to seal with the D rubber and flat foam others used, however due to the new style back this was not possible in the same way.

    Flat strip

    D rubber
    http://m.ebay.co.uk/itm/201026040945

    I also purchased the new clips with rubber seals. Expensive at £1.80 each x9
    [​IMG]

    As a result of the above i tried to find the best way to add the seals however there does not appear to be many options. You will see that the scuttle already has a rubber seal on the front edge but this doesnt do a good enough job.

    [​IMG]

    The only way i could see to improve things was to a strip on the bonnet itself along the angled front edge. I tried various positions and experimented with the D rubber and flat foam but due to the flush fit the flat foam seemed best.

    I therefore cleaned the paintwork and dried it so it was free from dirt and grease etc. I than ran the foam strip resting to bottom of it at the base of the angle so it wasnt visible when the panel would be on and still allowed for it to sit flush.

    [​IMG]

    Not convinced this would seal everything i also took others advice and taped up the holes to minimize water getting through.
    [​IMG]
    I was not keen on sealing them all as i didnt want water sitting underneath as it would eventually soak back into the strips i just fitted. I therefore left the two middle drain holes.
    [​IMG]

    I did try running a flat strip just below the angled one to assist with sealing but it meant the scuttle didnt sit flush. To avoid wastage I removed this and used it to seal the top edge just in case. This can be seen in the picture above.

    Once you have done all the above you will need to poke small holes/slits in the tape for the bolts and new clips will go through but obviously not the others. Although these should help i will say that they did make fitting the new clips difficult as they get stuck and need a little help to get them seated properly. I think i would avoid this next time but its up to you.

    Now for fitting the new clips to the scuttle. The old ones are removed by pushing the small tab down and sliding out towards it. They are quite tight. The new ones slide in the same way.

    [​IMG]

    Once you have done this, its time to put the panel back on in the reverse order.

    Fit the washer jet
    Clip washer piping to back of scuttle (i realised i forgot to do this and only realised once finished so was cursing as i now have to take it all off again and will probably end up breaking my new clips)
    Offer scuttle up to bonnet
    Slide it over the bonnet to get the two edge lips in place
    Put in first couple of bolts star bolts underneath to hold in place
    Now pop all clips through holes
    Fit remaining bolts continuing to check alignment of scuttle outside
    Refit washer pipe rubber surround
    Refit soundproofing
    Check washers work
    Job done!

    As stated i have only just done this today so dont actually know how successful it will be but due to the fact its a design fault i dont think there is much else we can do other then monitor and manage it over time.

    I am no expert and have only tried to do what others have done but hope this will be a little bit clearer for people that need a little more step by step like me.

    In all honesty although its sits alot better and snug to the bonnet, it is still taking in water. Im not sure if thats cos I left the two drain holes uncovered or if its soaking through the foam from outside, so I am going to try seal the other two holes first and see what happens. If you can use rubber to seal it instead of foam its less likely to let water penetrate through

    Hi there,

    I've had the dealer 'fix' for this done but my sound proofing is still getting wet. I have ordered some plasti-dip to seal the sound proofing. I did notice however that at least 2 of my scuttle clips are broken. Do you have the part number of the new ones with rubber washer so I can order some from the dealer. This is an annoyance, especially since it never happened on my old 57 plate leon. Its really bad on my 11 plate FR, with as much as a mug of water dumped out over the engine if its been sitting before I open the bonnet. I suppose it wouldn't be an issue if I lived outside of Barcelona.

    Cheers, James

    The second digit is the letter L not 1. It wouldn't post it in capitals (even though it has in this sentence).

    Might be cheaper to go to a diy store and find some small rubber washers as the clips are nearly £20 in total

    Be careful filling up holes as they are there for a reason.

    To allow water to drain out so it doesnt gather underneath the scuttle

    id did take off my bonnet crap to have a look where it was coming from but still none the wiser so i put a plastic bag over the coilpacks and put the hose on for 30 seconds or so with the bonnet closed
    then noticed a big puddle bang in the middle ofd the coils but no actual holes there in the bonnet???

    I think the only true way to stop it is to silicone the very edge of the scuttle itself so water cant get under it in the first place. But it would have to be done very neatly and will be a pain if it ever needs to be taken off

    Agreed you need to stop the water getting through the scuttle not just block up the hole so the hole thing fills with water.

    I put one of those rubber D-shape strips around the underside of the plastic strip before the weekend and didnt plug up the lowest central hole this time.

    The showers we had in the week didnt leak, but the torrential stuff last night did.
    It leaked out of the hole i didnt fill, onto the engine cover, behind the Cupra plate, through the clip holes and collected in the bottom half of my engine cover! Had to empty it out lol.

    My clips have the rubber washers, and i have the 2 holes further up plugged, so i will put the plug back into the bottom hole, and then hopefully the water will just collect and drain out the back when i open the bonnet.

    Honestly when you think of the technology and precision that goes into producing a car, and then they make this totally retarded idea to house the screen washers. Wtf were they thinking.
