Perhaps it went a bit like this with not changing the water pump on this particular vehicle Cliff:-
It had only done 25k miles, and if it were mine, I wouldn’t have changed it in this case, solely based on experiencing the affects of fitting some aftermarket pumps which prove to be troublesome in a short space of time. In fact, by the same logic, I wouldn’t be in a rush to automatically change a 47K pump, but I too would want to inspect it. A new pump would have to be VAG only for me (in caps).
I’ve also been disappointed with the bearing quality on some hitherto respectable branded tensioners - rough as a badger’s whatsit. I note that that particular ‘manufacturer’ is now marketing full timing belt kits under their own brand name, so it becomes choose wisely, and for me ( again in caps) VAG pump only.
Kind regards,
Gareth.
