Transmission Fluid Change:

Audi officially lists 'lifetime' fluid for the Tiptronic transmission, but proactive replacement every 60,000-80,000 miles (96,000-128,000 km) is highly recommended for longevity, especially for a performance vehicle.

Brake Fluid Flush:

Every 2 years, regardless of mileage.

Power Steering Fluid:

Pentosin CHF 11S (or equivalent hydraulic fluid meeting spec)

Air Suspension:

Leaking air springs, compressor failures, sensor issues leading to ride height errors.

Ignition Coils:

Premature failure of ignition coils can lead to misfires and rough running.

Camshaft Timing Chain:

While generally robust, wear or tensioner issues can arise over time, requiring significant labor for repair. The timing chains are located at the rear of the engine.

Transmission Mechatronics:

Occasional issues with the electronic control unit (mechatronics) of the Tiptronic transmission.
