Renault Laguna 1.9 dCi F9Q engine:

The main differences between the F9K and F9Q engines are the number of valves (8 vs 16), the camshaft configuration (SOHC vs DOHC), and the power and torque outputs.
The F9Q engine is generally considered to be a more refined and efficient version of the F9K engine, but it is also more complex and expensive to repair.
