Elise S2 flappy noise - help

[whygee02]

I posted a while ago to report a kind of flappy/banging noise coming from the rear drivers side. I'm guessing it doesn't sound serious enough to be suspension (maybe it is tho), but sounds more like a gentle flappy noise like a panel not secured or something. Any ideas anyone as its doing my head in. It even does it on reasonably smooth roads where the suspension isnt being tested.

Best I can describe it is - imagine a traditional car with spare wheel under the boot with the usual hardboard type cover in the base of the boot - imagine the cover not been properly secured so flaps/bangs a bit when driving.

I've done a quick 2 minute 'non-technical' walk around inspection, and the roof, boot lid etc etc are all secured fine.

Any ideas anyone - please....

Just a thought have you checked the under tray and rear diffuser they might not be bolted together fully

Thats the kind of thing I'm thinking it could be. Can this be checked with the car on the road or does it need to be on ramps etc?

Sorry to sound like a bit of a numpty but I'm still fairly new to the Elise.

They all do that , it happens when you get a pigeon trapped behind the wheelarche liner .

Excellent will take a look at lunchtime - also the nice guys at Formula1 have offered to do a road test with me, to see if they can find out what it is. Thanks again !!

I had a similar thing, it was the plastic grills over the side air intakes had become loose. Give them a wobble & see if they are secure.

I think it maybe sorted, the nice guy at formula 1 went on a roadtest with me and reckoned it's a thin pipe in the engine bay heating up and resonating off another when I go over bumps. He's had a fiddle and hopefully its sorted, if not he showed me what to do to do additional fiddles with.

Thanks forumla 1, touchwood thats it!!
