Just a update for future use. 2011 320d e90
The plastic door located on the underside is where the plug is located. Number 17 socket is the size to remove it.
Bmw have made the switch to shell last year. While supply is a little slow this what the bottle looks like.
The ect is newer and your best choice and what bmw sold me last year. Now they run out of stock I managed to get the ultra extra from goldwagon for under R100. The two oils shown are 100% the same just one has the ect additive and the other not.
I am much happier with shell, as the castrol has much less smooth and discolouring was bad. Shell comes out cleaner. Car takes around 5.5L and oil do a oil change when the motor is gold. Never throw cold oil in a hot motor.
Just a pic on the oil filter and it's bits. One is a seal for the oil filter cap and the other is a new sump plug washer.
Still better to buy oem service parts.
Location of the oil filter. Remove it with a 27 socket. Don't make it to tight. On the side of the car with the radiator water bottle.
