Problems:
Oil consumption
Many Audi A4 models, including those with the Flex Fuel Capable engine, are known for excessive oil consumption. This may require frequent oil top-ups and can indicate underlying issues with piston rings or valve seals.
Timing chain tensioner failure
The timing chain tensioner in some Audi engines has been known to fail, which can lead to catastrophic engine damage if not addressed promptly.
Carbon build-up
Direct injection engines, like the one in the Audi A4, can suffer from carbon build-up on the intake valves. This can lead to reduced performance and efficiency.
Fuel injector issues
Flex-fuel capable engines can have issues with fuel injectors, especially if E85 is used frequently. This can cause rough idling, misfires, and reduced fuel efficiency.
Coolant leaks
Some 2015 Audi A4 models have been reported to have issues with coolant leaks, which can lead to overheating and potential engine damage if not addressed.
Turbocharger problems
If the vehicle is equipped with a turbocharged engine, there may be issues with the turbocharger, such as oil leaks or bearing failures, which can affect engine performance and longevity.
Emission system faults
Given the specific emission standards (BIN 5 / ULEV II) the vehicle adheres to, there might be issues with the emission control systems, such as the catalytic converter or oxygen sensors, leading to engine warning lights and failed emissions tests.
