Sorry if im going over what some of u might already know but i thought i share some info.

Had a nice chat with SA at Brisbane BMW regarding the serving diesel engine. Diesel engines has no inspection II service like the petrol engines. Instead, according to the guildlines, every 3rd oil change extra work needs to be done which include fuel filter, micro filter and air filter. So technically I was suppose to get that all replaced during the last service last month but because the SA that looked after me this time was a newbie so he forgot to get it done for me.

Might book car in to get the rest of the stuff changed. Apparently according to the dealership, oil separator, which im guess is fuel filter, if not replaced will cause smoke in exhaust.

But still, i think I will get dealership do the extra service every 2nd oil change instead of 3rd oil change just to keep the car at optimal condition.
