The 1.8-liter Peugeot EW7J4 or 6FZ engine was produced from 2000 to 2008 in France and was installed on a number of popular mid-size models of the concern, such as 406 and 407. Around 2006, this power unit began to be replaced by an updated EW7A engine.

- Peugeot 406 I (D8/D9) in 2001 – 2004;
- Peugeot 407 I (D2) in 2004 – 2006;
- Citroen C5 I (X3/X4) in 2004 – 2008;

Disadvantages of the EW7J4 engine
- Most of the problems of the power unit are somehow related to lubricant leaks;
- Oil likes to ooze from under the valve cover, leak from the breather, or just burn out;
- In second place are frequent failures of ignition system components, especially coils;
- The culprit of the floating engine speed is contamination of the throttle or idle speed controller;
- After 100,000 km, engine mounts and hydraulic lifters often require replacement.
