Peugeot 407

The large saloon and estate that replaced the 406, and the model where PSA's 2.0 and 2.2 HDi engines with a particulate filter and its additive system reached volume — which is where most of its diagnosis lives. The additive tank holds a cerium-based fluid dosed into the fuel to lower the filter's regeneration temperature, and when the tank empties or the dosing pump fails the filter stops regenerating properly and the car sets soot-load and additive codes together. Refilling without resetting the counters leaves the fault in place. The 3.0 V6 petrol and the 2.7 HDi V6 are Ford-PSA joint designs. Electrically, the BSI body computer is central and a low battery produces convincing but false faults across several systems.

Service information

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:

  • The car — make, model, year and engine. The same fault behaves differently on each.
  • What you measured, not only what you replaced.
  • What actually fixed it — or that nothing did, which is worth knowing too.
