Oil pan gaskets on all BMWs have been a problem for decades. I've owned 6 BMWs and did coolant flushes every two years on all of them -- cheap insurance. Front differential failed on my E91 out of warranty at 52k mi so I should have flushed it and transfer case. Also ZF factory recommends a transmission flush at 60k.
