That is the expansion tank kit, you could also get the full cooling kit, as the hoses likely are brittle and need replacing too:

Is there a DIY for the X5 3.0i ??? I need to change mine also.
I have changed one out on my E46 before but there are usually small differences somewhere.
I don't really like surprises when working on cars. Also I'm not good at finding hidden bolts. LoL
I already have the ET and a new AT thermo.
