Problems:
Oil leaks
Common in V8 engines, oil leaks can occur from valve cover gaskets, oil pan gaskets, or rear main seals.
Timing chain issues
The timing chain can stretch or the tensioner can fail, leading to engine misfires and potential severe damage.
Carbon buildup
Direct fuel injection engines like the one in the S8 can suffer from carbon buildup on intake valves, affecting performance and fuel economy.
Turbocharger failures
If equipped with a turbocharger, it may fail due to oil starvation, contamination, or general wear and tear.
Coolant leaks
Possible coolant leaks from the water pump, radiator, or hoses can lead to overheating and engine damage.
Ignition coil failures
The ignition coils can wear out over time, causing misfires and rough running.
Faulty pcv valve
A malfunctioning Positive Crankcase Ventilation (PCV) valve can lead to oil consumption issues and rough idle.
High-pressure fuel pump (hpfp) failure
The HPFP can fail, leading to low fuel pressure and poor engine performance.
Thermostat issues
A faulty thermostat can cause the engine to run too hot or too cold, impacting performance and efficiency.
