engine light on
« on: April 07, 2014, 10:28:28 PM »
can anyone elaborate on those codes please
4595 - smoothness control cylinder 6
4596 - smoothness control cylinder 3
4C04 - exhaust gas temperature
436D - unknown DTC fault

I am new to all of that BMW issue thing, I do have some issues and awaiting the computer to be replaced but dealer allowed me to drive the car which allowed me to read the codes.  I know they did replace one injector and mass air flow sensor and some sensor for EGR I think, no paper work yet and I don't remember all they have told me over the period of time.  They also did the walnut blasting.  The car drives nicely, just did my first trip in it back to fort mac and it was awesome but the service light came back on.
