Engine ECU Repair Bosch EDC16 Peugeot/Citroën: Symptoms and Solutions
Is your Peugeot or Citroën with an HDi engine struggling to start, losing power, or showing a check engine light?
It might be due to a faulty Bosch EDC16 engine control unit (ECU). This essential electronic component can fail in various ways, but fortunately, we offer reliable and cost-effective repair solutions.
Symptoms of a Faulty Bosch EDC16 ECU
If you notice one or more of the following signs on your Peugeot or Citroën, your EDC16 ECU might require special attention:
- Engine doesn’t start at all;
- Sudden or gradual power loss;
- Unstable engine behavior (misfires, stalling);
- Cooling fan running continuously;
- Check engine light illuminated on the dashboard;
- Error message on the onboard computer;
- Presence of fault codes like P0606 (internal processor error) or P2146 (injector power supply issue).
How to Diagnose an Engine ECU Fault?
Running a diagnostic scan is often the first step. However, a faulty ECU does not always show clear error codes. It is then essential to compare behavior with a known good ECU (if possible).
If you’re not equipped or trained, contact a professional with the proper diagnostic tools. This allows for a precise diagnosis and avoids unnecessary replacements.
