Header tank leak

[alec.m]

Header tank has started to leak from a tiny crack. Found a few on ebay at a decent price. Some have a sensor at the bottom but the MEYLE one I`m thinking of getting doesn`t mention that. I`ve felt underneath the one in the car and can`t feel any wires there. Am I missing something?

Is it this one https://www.realoem.com/bmw/enUS/showparts?id=CN52-EUR-01-2002-Z3-BMW-Z3_30i&diagId=17_0168
No sensor shown on the diagram, double check on oem site by putting in your last 7 letters and digits to pull back your car, link I posted was on a 2002 M54 3.0l model

Thanks Colb, I`d looked at that diagram, mines a 2000 3.0, and that`s what was confusing me as some of the ebay ones were using that part number and the vehicle check was showing it fitted mine. The MEYLE one didn`t appear to have anything underneath so I`ll go for that. Incidentally are you finding realoem a pain with the number of pop up adds coming up on it now?

The pop-ups are annoying, but they're a small price to pay for the use of the site. Finding the number, and cross-referencing it through the BMW range comes in handy plenty of times.

Not seen any pop ups so far
