Hello everyone, as in the topic, what are these modules and what do these errors mean, the engine light is flashing. If someone had a whole list of MP4 errors, I would be very grateful.
ACM is an exhaust gas treatment module (commonly called AdBlue.) The fault is the exceeded NOx value after the catalytic converter on the A57 sensor. It can only be deleted via VeDoc after testing the NOx sensors and possibly replacing them, sometimes 2. CPC is a fault in CAN communication with the MCM (engine module) on CAN four.
I work on Star C4 and I didn't need to make a list of faults, I know most of ACM and MCM by heart. I will not copy the entire list for copyright reasons. Sorry, there will be no torque limit for this fault. There will be a limitation in the same fault, but with the following code: 0C1101 after the next engine start.
