Blue Cooper Melting hood scoop

After a long trip in warm weather last week, the hood scoop on my '08 MCS Clubman had developed a wavy contour. It's right over the turbo, and it's made of plastic, so I'm not too surprised. I see there are a few aftermarket heat shields available on the web (with text telling us warped scoops are common).

Questions:
1) Has anyone had success in getting MINI to replace a warped scoop after warranty's out?
2) Any thought on why it took five years for this to happen?
3) How do those aftermarket heat shields work? I note one is described as "factory" but neither my '08 nor my '13 MCSs have a shield.

Hi Stirls. One hot day in 2012 some seagull poo baked itself onto my R56 bonnet and took ages to polish out. I began to focus on bonnet temps and found US R58 coupe owners were complaining about discolouring bonnet stripes on NAM and some deliveries were being made with the insulation in the pic below.

My UK dealer said it wouldn't fit (even tho R56/57/58/59 bonnet numbers were the same according to RealOEM) and specially ordered the part from Germany with the veiled threat that there would be no refund. Cost was 62.51inc.

I'm pleased 'I stuck to my guns' though - it fits perfectly and keeps the bonnet cool w/out affecting the coolant temps I was measuring for another issue.

I gather the plastic part that warped is merely cosmetic and serves no useful purpose in the Gen2s.

But on mine the scoop grille part slots are open so must allow some cool air to pass into the engine compartment?

Yes Nun, the scoop on the Gen1 MCS was very necessary for the intercooler behind it on top of the engine but this (as you probably know) is moved further down below the bumper in the Gen2 MCS well away from the bonnet in front of the lower half of the radiator in the airstream...

I've blocked up my own R56 intake to ensure water doesn't run over behind the insulation if it gets very wet. This doesn't affect the engine temp in the slightest, I've found.

In fact IMO this redundant scoop doesn't significantly add to engine cooling whilst in motion; it's a fraction of the total 'cooling' area. You could argue, though, that it allows a small amount of bonnet/engine cooling by convection when stationary...but this isn't necessary if the insulation is in place. You could also argue that it allows the engine to cool down more slowly.

Anyway, just my thoughts...

Hi, I have a 2010 clubman S chilli, I have had numerous major problems. When the super knock first began to malfunction - before it was diagnosed as this, under extreme engine heat, the hood scoop buckled and warped and it was replaced 50% of costs by mini -Australia and 50% by me, Cheers Tracy
