What is the code P1124 $7E8 on 2008 BMW E87 120i? How to fix it?

Question

I used Autel AL319 and error code P1124 $7E8 and "Please refer to vehicle service manual" were shown.

Answer 1

Should ignore the $7E8 since you already have the P1124 code.

For the P1124 code, replacing the Differential Pressure Sensor should take care of the problem.

The code 7E8 is not an OBDII code. When the OBDII scanner plugs in your vehicle, the OBDII scanner gets the 7E8 ($7E8) code from the ECM. The code is a menu of systems that the OBDII scanner can access. OBDII scanner interprets the code and displays the menu. Some scanners can't solve these codes and show the codes instead of the interpretation. Clicking on the code menu will read the OBDII codes (e.g. P0420 or P0455), if any, from that system.
