I have a 1998 BMW 318I, it is showing a P1423 Error Code. What the heck is that?
Hi there
This is an issue with the secondary air injection solenoid on bank 1. This could be an issue with the air pump or a blocked hose, possibly the sensor that see's the air flow. Here is some more info on the code for you.
