Audi A8 2002 3.0 TDI quattro engine ASB

Engine reliability and common problems:

The camshaft is driven by a set of four chains, which means that replacement costs are high.
Overall, this engine can last around 290,000 to 490,000 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 2967 cm3
Number of cylinders 6
Bore (cylinder diameter) 83 mm
Stroke length (piston move) 91.4 mm
Compression ratio 17 : 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.

More service info
Timing chain change interval 300,000 km (specified), 200,000 km (recommended)

Fuel system Common Rail
