Why not?
Probably as good as or better than the original - which are notorious for reading incorrectly and failing.
Hardly a serious issue if it does fail either.
Sorry, i was not trying to knock your alternative part find.
Probably a sweeping statement but in the past i have bought new parts from ebay, they usually failed, leaked or wore out within a short space of time.
So have been a complete waste of time and money, hence my view.
You just have to be careful what you're buying, i still buy after market parts but from local motor factors or reputable suppliers, or genuine parts from ebay would of course be fine.
