Hello, so i just did my wifes 2011 328xi front diff (similar setup) and it was straight forward. I saw a couple post for front diff fluid change on E70's but all were on 3.0 and it seems the 4.8 has the a hose ( i think its the oil cooler line) right in the way of the fill bolt. RRRRR!!
Has anyone done it on the 4.8, and do you have any tricks to offer?
