Hi:cool!:

New to this forum and hopefully we all can help eachother.

I just purchased 2018 X4 20D

It's running at 70,000 now and I have changed TC, Engine,brake and transmisson oil via our family friend mechanics.

I have two questions.

1) my current model does not have adblue and wondering what is the reason for disel car not having adblue and my wife X5 has adblue.

2) Any recommended Disel fuel additive to clean some injector and improve engine function?

Thank you in advance.
