Expansion tank recommendations

Hi all,

It appears my N52 has developed the cracked expansion tank so just looking at where to get a new one from & if it's worth going for genuine BMW or OEM?

Can someone confirm the part number is 17117573781 because I was looking at this..

Conversely an OEM is around £35 but I don't want to buy cheap, pay dear.

Thanks

Go for genuine BMW. A lot of the cheaper ones look OK, but don't quite fit right.

I bought my replacement from GSF two years ago. Fitted no problems, and no leaks

Thanks for the replies. The part number I actually need is 17117573751. Just need to definitely confirm it's the tank. The car would decide to do this as soon as the weather goes colder
