The 4.0-liter diesel Audi ASE or A8 4.0 TDI engine was manufactured between 2003 and 2005, and prior to its initial redesign, it was exclusively fitted on our well-liked A8 sedan. This V8 diesel quickly gave way to 4.2 TDI engines due to its poor timing design.
The EA898 series also includes: AKF, ASE, BTR, CKDA, CCGA, CZAC, DHVA.

Disadvantages of the Audi ASE engine
Weak timing chain tensioners on this motor frequently caused a jump;
Additionally, the intake manifold flaps frequently fell into the cylinders after falling off;
Fuel system malfunctions are typically the cause of the remaining severe engine issues;
Turbines and hydraulic lifters have a much shorter lifespan when oil is saved. Make sure the glow plugs are in good condition or they will break easily when unscrewed.
