Mornings folks. Well after my car being trouble free for a while and having CBU cleaning 10k miles ago, the damn SES light came on.
This is what I see:
Code 4B05 - Set zero adjustment cylinder 4 injector.
Code 4AE6 - Set zero adjustment cylinder 2 injector.
Code 4593 - Smoothness regulator cylinder 2 injector correction amount by adjusting the range.
Code 4592 - Smoothness regulator cylinder 4 injector correction amount by adjusting the range.
My car idles a little rough and when I accelerate slowly it seems to stutter. All these codes were taken from the BMW Carly app. I had CBU cleaning done at around ~59k miles and I just hit 71k miles yesterday.
Thoughts? Could it be another CBU problem? Maybe the injectors are really bad this time? I cleared the codes to turn off the SES light and now it was idling ok...for now.
I searched the forum and everything seems to fall back on CBU...again.
