On the 2013-2020 Audi RS6 4.0T V8, the 4.0T twin-turbo V8 in RS6, RS7, and RS Q8 (2013-2020) has a CRITICAL design defect in the turbo oil strainer/screen. The oil strainer uses a mesh filter that's too narrow and gets blocked with oil and carbon deposits, starving the turbochargers of oil and causing complete turbo failure. This affects BOTH turbos and requires $8,000-$12,000 replacement. One dealership technician reported seeing 20+ failures in one year in a single region. Audi issued TSB extending coverage to 2017 models, but refuses warranty coverage for out-of-warranty vehicles despite it being a DESIGN FLAW. RS246.com forums are full of turbo failure cases. This is the most serious and expensive reliability issue with the 4.0T engine.
PREVENTIVE FIX: Replace turbo oil strainers with updated parts ($1,500-$2,500) BEFORE failure. Some specialists offer strainer upgrade service. If turbos have FAILED: Replace both turbos ($8,000-$12,000 installed). Check TSB eligibility with Audi dealer—some 2013-2017 cars covered. PREVENTION: Change oil every 5,000 miles (NOT 10,000) with high-quality synthetic. Monitor for ANY boost loss and address immediately. Consider extended warranty if buying used 4.0T car.

On the 2013-2023 Audi RS6 4.0T V8, the 4.0T twin-turbo V8 in RS6, RS7, and RS Q8 suffers from severe carbon buildup on intake valves due to direct injection. The high-performance nature and twin-turbo setup means carbon accumulates faster than in lower-output engines. Over 60,000 miles, carbon restricts airflow causing rough idle, misfires, and power loss. The V8 configuration requires removing both intake manifolds, making walnut blasting more expensive ($1,200-$2,000) than 4-cylinder engines. RS6.com forums recommend cleaning every 60,000 miles as preventive maintenance. Failure to clean can cause valve damage requiring expensive cylinder head work on the $120,000+ RS models.
WALNUT BLASTING: Remove both intake manifolds and blast walnut shells through all intake ports ($1,200-$2,000 for V8). Repeat every 60,000 miles. PREVENTION: Install catch can ($500-$800 for twin-turbo setup). Add Liqui Moly Intake Valve Cleaner to every oil change. Change oil every 5,000 miles. Drive car hard regularly.

On the 2013-2023 Audi RS6 4.0T V8, the RS6, RS7, and RS Q8 with 4.0T V8 engines experience premature motor mount failures due to the engine's high torque output (600+ lb-ft). Motor mounts wear out between 40,000-80,000 miles, causing excessive engine movement, vibrations, and clunking noises during acceleration or deceleration. The high-performance nature of RS models accelerates mount wear compared to base models. Failed mounts cause driveline stress and can damage other components. RS246.com forums report this as a common issue on high-mileage RS models. Replacement costs $800-$1,500 for all mounts.
Replace failed motor mounts with OEM or upgraded mounts ($800-$1,500 for all mounts). Upgraded aftermarket mounts (034 Motorsport, ECS) offer better durability for high-torque engines ($400-$600 per mount). If you drive aggressively or track the car, consider upgrading to performance mounts preventively. Monitor for vibrations and clunking—early replacement prevents driveline damage.
