Expansion tank leak

I had a small puddle everyday after work right under the expansion tank so I bought a new tank from ECS Tuning for around $50 and part #3 in the diagram. When my mechanic got in there though it was actually the mounting plate #1 where the tank sets in was cracked so I needed to get #1 for $185 or so from the BMW dealer due to time constraints.
All is well now.
