ECU Faults in Vans: Why Peugeot, Fiat and Citroën Need Specialist Diagnostic
The Fiat Ducato, Peugeot Boxer and Citroën Relay share some of the most advanced onboard electronics in the commercial van segment. When something starts going wrong in that network, the symptoms are often subtle at first: a warning light that clears itself, fuel consumption that drifts upward, a van that feels slightly off under load. RACQ responded to 755,000 roadside rescues across Queensland in FY2023, with battery and electrical faults the leading cause. In European vans, battery management is ECU-controlled, meaning many of those callouts trace back to an unresolved electronic fault. This post explains what the ECU actually manages, why generic scan tools miss more than most owners realise, and what specialist diagnostics finds that a basic scan does not.You said: too long
Diesel Van Maintenance Guide: How to Extend Engine Life in Fiat, Peugeot & Citroën Vans
The Fiat Ducato, Peugeot Boxer and Citroën Relay all share the same engine platform.

The repair bill is not just for the part that failed. It covers the tow, the emergency labour rate, the day of lost bookings, and the scramble to find a replacement vehicle. Unplanned repairs cost significantly more than the equivalent work done on a schedule. For a Brisbane business running four or five vans daily, one unexpected failure in the wrong week can wipe out a month of margin.
