May be cheap as chips at the dealer give them a try, things like that can be surprisingly less hassle than sourcing one from a breaker!

The quality of the cap BMW used for the RH drive conversion would shame a can of supermarket own brand engine oil.
The cap has a fairly common thread and size, and a far better quality replacement can be found on other makes in a scrap yard.
I've no idea if they are still available from BMW, or what the current price is, if they are, but the cap used to be about £1.50, and the whole bottle, including filter and cap, was around £4.
