Need to vent. My 09 E70 decided to start leaking coolant, right after I ran out of warranty. After a few weeks of topping up, had it inspected - 2 cracks in the rad.

Looks like BMW is up to something, as they are selling newer radiators with an adapter for older models - in other words they had a design flaw.

$979.76 later, I'm on the road again...
