Bosch diesel electronic injection high-pressure common rail system fault codes (II)

by MOU YONG HONG on December 01, 2021

All fuel injectors will wear out during use, and some malfunctions will occur. But most of the faults are minor faults, and some error codes will also appear. If we do not understand these Bosch diesel EFI high-pressure common-rail systems, it is just a small problem and it will consume a lot of time. Therefore, we understand some Bosch diesel EFI high-pressure common-rail systems, which is very important for us.
