Timing chain issues
The timing chain tensioner can become faulty, leading to potential engine damage if not addressed.
Coolant leaks
The plastic components in the cooling system can become brittle and crack, causing coolant leaks.
Engine misfires
Ignition coil failures are common and can lead to engine misfires, affecting performance.
Carbon build-up
Direct fuel injection engines, like the one in the S4, can suffer from carbon build-up on intake valves, leading to reduced efficiency.

Fuel pumps can fail, causing the engine to run poorly or not start at all.
Vacuum leaks
Aging hoses and connectors can develop leaks, affecting engine performance and fuel economy.

A faulty PCV valve can cause engine performance issues and increase oil consumption.
Thermostat failure
