Engine reliability and common problems:

Pretty reliable engine with great resource. Overall, the chains are more reliable than in BMW N-series engines, but also tend to stretch under heavy use. The engine requires good quality fuel, maintenance and oil, otherwise problems with the common rail system can be expected. Problems are most commonly associated with the EGR valve and intake manifold.
Overall, this engine can last around 210,000 to 360,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
Engine displacement 1995 cm3
Number of cylinders 4
Bore (cylinder diameter) 84 mm
Stroke length (piston move) 90 mm
Compression ratio 16.5 : 1
Camshaft drive Timing chain

Chain motors are considered more reliable, chain replacement usually is required less often than a timing belt, but they are often louder and vibrate more.

Fuel system Common Rail

Common rail fuel injection provides more engine power, is quieter, more environmentally friendly and offers better fuel economy, but is more expensive to maintain and repair.
