Plastic in sump

[VWB]

Oil in sump - removing oil pump.

Hi I have recently brought a Golf GTI FSI. The cam chain has snapped, tensioner is broke an the cambelt has jumped some teeth. The oil was also overfilled by 3 litres. I decided to check the oil strainer as I know these are prone to blocking and found shards of plastic in the sump. Doing various searches I cannot find any searches on this - has anyone had or know of this problem as I have no idea where the plastic has come from?
Also has anyone got any info on how to remove the oil pump?
Any help would be greatly appreciated.

Hi. I think I found where the plastic has come from. It's called an oil restricter but I don't know where it goes and had a look on ETKA and it doesn't show where it goes. Does anyone know where is goes or anywhere I could look. Many thanks.

If the cam chain has snapped then the plastic is probably from the chain tensioner.  Not sure on this restrictor though.

Managed to get this sorted. Thanks for the help.
