04B103660C oil pan/sump lid/cover aftermarket alternatives

In the process of servicing my 2016 Fabia SE, I managed to spill oil all over the foam-y cover over the sump (lesson learned, I shouldn't have been lazy and removed this!).

The car passed its MOT last month with an oil leak advisory, which I'm 90% certain is just residual oil sitting in the saturated cover.

I would like to replace this cover – if nothing else, so I can monitor a potential leak – but the OE part is frightfully expensive: https://www.skoda-parts.com/spare-part/04b103660c-oil-pan-lid-skoda-48047.html

Does anyone know of a cheaper alternative? Or does a sump tray typically come with this cover? Or do you reckon it would survive a good cleaning?

Sage advice much appreciated.
