The Citroën Technical Guide

Željko Nastasić and I are proud to present the Citroën Technical Guide. This book, available in PDF format, describes the functioning of all systems of interest in our Citroëns, from the early days of the DS until the most recent incarnation, the C5. It is not a service manual, thus you won’t find detailed circuit diagrams or repair procedures inside. Instead, it contains schematic illustrations and detailed descriptions of the various systems. It is not a mere compilation of excerpts from various books and brochures: it is a standalone guide written from ground up.

To help the reader understand every small detail, we decided to provide our own illustrations across the whole book. The figures appearing in service manuals, mostly copies of original Citroën technical illustrations of actual components or systems, often bury the main principles of operation under small and irrelevant details. In contrast to these, our illustrations are simplified, colored schematic diagrams focusing on the important concepts, not on the exact location of every single bolt or pipe.

At present, the guide comprises the following chapters:

  • Fuel Injection
  • Electronic Fuel Injection — Gasoline EFI and EMS systems
  • The HPi Engine — Newest gasoline EMS systems
