Are you doing the work yourself? Lots of the garages I’ve spoken to won’t allow you to supply the parts (on the basis that a lot of customer bought parts, particularly ones sourced from eBay, are low quality). Although I have no specific knowledge of the part in question.
Should I be concerned if I bought this to replace the one in the car?
I'm aware the warranty is as good as anything these days
Look at this on eBay
