The 1.4-liter diesel engine Toyota 2WZ-TV or 1.4 D-4D was produced from 2005 to 2007 and was installed only on the first generation of the popular Aygo model in the European market. This power unit was essentially one of the many varieties of the Peugeot 1.4 HDi engine.

Disadvantages of the 2WZ-TV engine
- This diesel engine has a good resource for such a modest volume;
- The Siemens fuel system is quite reliable, but is very afraid of airing;
- The PCV and VCV control valves in the high-pressure fuel pump deliver the most problems here;
- Regularly check the condition of the timing belt, as when it breaks, the valves bend;
- Another weak point of the engine is the crankcase ventilation membrane and the crankshaft damper pulley.
