Help with Multec central injection system faults (Opel Vectra B)

If it is not possible to read the fault memory with a reading device in an Opel workshop, you can also detect the defect using our tips in the "Help with faults" section.

Tip: When the battery is disconnected, the correction factors of the Multec central injection are erased. This means that the engine does not idle perfectly for some time after reconnecting the power supply. The fastest self-learning process for the correction factors occurs during a 5-minute test drive.
