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.

I orderd this gasket kit from VEP because the picture shows the right gaskets kit. with quality gaskets and a reinforced head gasket. the deliverd a gasket kit for a S4Q but low quality gaskets (1 was broken) and the head gasket was not reinforced. so i can not use that head gasket and have to oder a other one somewere else.
Vep sales very good part. Deliver on right time
Good seller
intake gasket was missing
