Ford and Peugeot collaborated to develop the 3.0-liter diesel engine known as the DT20C. Some of the company’s models, including the 407 and 407 Coupe, had the engine installed between 2009 and 2013. This unit produced power of up to 300 horsepower and 700 Nm on Jaguar or Land Rover vehicles.
DT17TED4 and DT20C are diesels in the DT family.
The engine was mounted on:
- Peugeot 407 I (D2) in 2009 – 2010;
- Peugeot 407 Coupe I (D2) in 2009 – 2011;
- Citroen C5 II (X7) in 2009 – 2013;
- Citroen C6 I (X6) in 2009 – 2012.

Disadvantages of the DT20C engine
This engine turned out to be very dependable despite its technical complexity;
Poor fuel is not tolerated by common rail piezo injectors;
Frequent oil and coolant leaks have been reported by numerous owners; a decline in the oil pump’s efficiency causes the system’s pressure to drop;
Oil starvation can cause the engine to jam or even turn the liners.
