Mercedes Coupes/Sedans/Wagons 1974-1984 Repair Guide

BOSCH ELECTRONIC FUEL INJECTION

Print

This system was used on 1974-75 V8 engines.

This system is a constant pressure, electronically controlled unit. The "brain" of the system, actually a small computer that senses the determining factors for fuel delivery, is located behind the passenger kick panel on the right-hand side.

A Bosch tester is necessary to accurately test the solid state circuitry and components, but there are a few checks that can be carried out independently of the tester.
