Good morning everyone and have a good day at work, a Mercedes Sprinter year 04/1999 312d engine code 602980 has come into the workshop, the vehicle does not go more than 90 km/h with the engine light on, we carry out a diagnosis and an error code P1352 comes out with the description: component B27 defective, not finding explanations with a colleague we went on the internet and found some information written in English that translated it spoke of a pin in the injection system.

With the chassis number we saw that out of five injectors a wire comes out of the first one, inside this injector there is a conical pin that moves when the injector is working, we tested it with a multimeter and in fact no signal came out of the wiring harness.

We ordered the part from Mercedes, fitted it, now the vehicle has been running for 15 days and has not given any more problems.

Greetings to all.

Claudio Terreni Tito.
