Electrical System Issues

The high TSB count suggests potential for various electrical gremlins, including sensor failures, module malfunctions, or intermittent connectivity problems. These can manifest in numerous ways, affecting anything from infotainment to engine performance. Estimated repair cost: $200 - $1,500+.

The Positive Crankcase Ventilation (PCV) valve can fail over time, leading to increased oil consumption and potential engine damage if left unaddressed. This is a known weak point on many turbocharged Audi engines. Estimated repair cost: $300 - $600.

Ignition Coil Failure

Ignition coils can degrade over time, leading to misfires and reduced engine performance. This is a common wear item on turbocharged engines. Estimated repair cost: $400 - $800.
