Underside of bonnet...

[White_Lady_170]

The Black carpet-like material attached to the underside of the bonnet, is it for sound deadening or is it to protect against heat?

what would be the consequences of removing this for a long period of time (idealy, completely)

It looks terrible, it soaks up water and then starts to grow its own colony of bacteria! I dont like it and want it gone... but is there going to be any negative effect on my bonnet if i do this?

Thanks

Spot on.Its to supress the sound so remove it only if you dont mind it quite a bit louder.Take it off and pressure wash it if you want it really clean but its under there out of eyesight anyway.
Doesnt soak up water much anyway cos of the heat from the engine.

mine must be a crappy design then, after washing the car and lifting the bonnet, the water runs out of it like a river!

cant be good for whatever it is in at the back of the engine that its raining all over...

Because its at the bottom of it (closet to the windscreen when bonnet is down, bottom when bonnet is lifted) it isnt getting much heat from the engine therefore its staying damp and there are white patches of fungi growing...

So basically its going to be more noisy but not going to harm the bonnet or paint because of the extra heat?

I don't think the black stuff is to do with heat but I do remember a mate of mine had a clio 16v that made the bonnet paint go like crackle effect in the middle due to heat damage.

mine has gone like it, i intend to wash it, wet hoover it and then give it a coat of black dye.

Cant say I've washed my car then immediately looked under bonnet for water running off it,but I am also in the process as we speak of having a new bonnet and probably under cover.Oh and wing etc.

underside of bonnet

I had my piece of cheap carpet replaced under warranty, after it looked like I was growing a botanical fungus garden. Replacement going the same way. Did hear a whisper that it`s made worse by water residue from washers (design problem). Wonder if problems been fixed on facelift?

Ive been running my Cupra with the cover off for the past two months and I have no adverse effects from heat etc. Go for it, just makes the engine a bit louder.

Also, it could be assumed that the bonnet would dissipate heat better without it on. Thus cooling the bay a bit maybe?

if i cant get mine replace by warrenty, i think i may lose it too as mines going all white..

quite horrible really...

 

[daveclayton]

i took mine off the day i got it. so thats nearly a year now and no paint damage to report. just makes the engine noise slightly louder do it people, remove the recycled carpet!

Its not that well painted under it either


Just get some engine bay spec Dynamat if you want to keep the sound down.

that is correct! more of a gold colour than white where can i purchase this Dynamat stuff and would it be worth doing? or would the same thing just happen with it...?

 

[leon_lib]

I think same will happen when it rains or you wash the car it'll get wet and then when you drive around it gets hot and that's bacterias growing place, maybe just jet wash and let it dry and just keep on top of it to prevent bacteria growing,

Mine has got the mould, could we worth removing then.

I have the same on my FR, after quite a bit of backwards and forwards with Seat customer services, they agreed that it was a design problem and a fix had been requested from their technical dept!!!!!!!

When I asked if they would change it under warrenty they agreed wtf the car goes in on Friday, the dealer is also going to change a 'plastic part' or 'it will just happen again'

wish me luck
