Engine under tray fixing screws?

[Pauls898]

I carried out an oil service on my Audi B8 3.0L TDI model year 2009 but on removing the engine undertray I found some of the metal retaining clips had rusted away and the screws wouldn't stay back in once removed but fell straight back out? I tried to order some replacement ones from eBay but the ones I ordered have been far too large and the screws don't even fit? Does anyone know or could look up the correct size and part number of these fixing screws and retaining clips so I can try to order the correct ones? These are quarter turn ones? Thanks

The grip pins are 8W0 805 121 and 91p each and the speed nuts 8K0 805 922 A at 95p each from Audi dealers or TPS, I think you need nine of each

Big thanks Crasher, I've ordered nine new one's might as well replace them all! Thanks
