I have a number of what look like these ADU6847L (copper crush washers - have two flanges and obviously crush together when compressed) - amongst a box of unused bits and bobs given to me.

I have used one previously on the vacuum pump line (oil was sprayed everywhere over the alternator and elsewhere) - the new crush washer fixed the problem!

Question - are these copper crush washers used anywhere else in the vehicle?

So the answer is yes, well on other vehicles at least.

So only two places on a Td5 - "Td5 turbo oil feed banjo pipe & alternator VAC pump banjo pipe".
