The 2022 RS5 with the EA855 evo 2.9L twin-turbo V6 is still relatively new, but the platform shares DNA with earlier B9 RS4/RS5 models that revealed weak points under high-performance use. Most concerning are turbocharger oil supply issues and transmission cooling failures that can cascade into catastrophic damage if ignored.
Transmission Oil Cooler Failure Leading to Fluid Contamination
Occasional · high severity
Typical onset: 40,000-80,000 mi
Symptoms: Harsh or delayed shifts, especially when cold, Milky or discolored transmission fluid on dipstick, Check engine light with transmission fluid temperature codes, Limp mode activation under hard acceleration
Fix: Replace transmission oil cooler and flush entire system. If coolant contaminated the trans fluid, internal clutch packs may be compromised requiring full rebuild. Cooler replacement alone: 4-6 hours. Full trans rebuild if contaminated: 18-24 hours.
Estimated cost: $1,800-3,200 for cooler only; $8,000-12,000 if transmission internals damaged
Turbocharger Oil Feed Line Coking and Bearing Failure
Occasional · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Excessive blue smoke on cold starts or under boost, Metallic whine or whistle that increases with RPM, Loss of boost pressure, reduced power output, Oil consumption exceeding 1 quart per 1,000 miles
Fix: Carbon buildup in oil feed lines starves turbo bearings. Both turbos typically need replacement along with feed/drain lines and oil system cleaning. Requires engine-out or extensive disassembly on some RS5 configurations. 14-18 hours labor per turbo, often both done simultaneously.
Estimated cost: $6,500-9,500 per turbo; $11,000-16,000 for both
Transmission Mount Failure from High-Torque Launches
Common · medium severity
Typical onset: 30,000-70,000 mi
Symptoms: Clunking or banging on hard acceleration or shifts, Excessive driveline vibration at idle in gear, Visible sagging or torn rubber on mount inspection, Shifter movement or vibration in manual mode
Fix: The ZF 8-speed mounts tear from repeated launch control use or aggressive driving. Replace both transmission and subframe mounts as a set. 3-4 hours with proper lift access.
Estimated cost: $800-1,400
Carbon Buildup on Intake Valves (Direct Injection)
Common · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: Rough idle, especially when cold, Misfires on cylinder-specific codes (P0300 series), Loss of low-end torque and throttle response, Failed emissions testing in some states
Fix: Direct injection means no fuel washing over valves. Walnut blasting required every 50-60k miles under spirited driving. Remove intake manifold, blast each port. 6-8 hours labor.
Estimated cost: $900-1,600
High-Pressure Fuel Pump Failure
Occasional · high severity
Typical onset: 40,000-90,000 mi
Symptoms: Long crank or hard starting when hot, Rough running under boost with fuel trim codes, Sudden loss of power at wide-open throttle, Metallic ticking from engine bay at idle
Fix: HPFP on cam-driven systems can fail internally, sending metal debris into injectors and fuel rail. Replace pump, fuel filter, and flush rail. Inspect injectors for damage. 5-7 hours labor.
Estimated cost: $2,200-3,800
Piston Ring Land Failure Under High Boost
Rare · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Severe oil consumption (1 qt per 500 miles or worse), Loss of compression on specific cylinders, White or blue smoke under boost, Catastrophic loss of power with possible rod knock
Fix: Tuned or heavily tracked RS5s can crack piston ring lands. Requires full engine-out rebuild with forged pistons and re-ring. Some opt for short block replacement if cylinder walls scored. 35-45 hours labor for complete rebuild.
Estimated cost: $15,000-25,000 for full rebuild; $20,000-30,000 with short block
Owner tips
Change transmission fluid every 40k miles despite 'lifetime fill' claims — prevents cooler and clutch pack issues
Use only Audi-spec 0W-20 or 0W-30 oil and shorten intervals to 5,000 miles to combat turbo coking
Walnut blast intake valves every 50-60k miles before misfires start — preventive measure pays off
Avoid extended idling and short trips; these engines need full heat cycles to prevent carbon buildup
If tuning, budget for upgraded transmission mounts and plan for shortened turbo lifespan
Buy only with full service records and pre-purchase compression test; the 2.9T is potent but expensive when things go wrong, and 2022s are now exiting warranty.

Volkswagen Group of America, Inc. (Audi) is recalling certain 2022 RS5 coupe and RS5 Sportback vehicles. The value for the maximum combined weight of occupants and cargo on the B-pillar Tire and Loading information label is incorrect. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire and Loading Information."
Consequence: While referencing the B-pillar label, the operator may overload the vehicle, increasing the risk of a crash.
Remedy: Dealers will install a corrected label on the B-pillar, free of charge. Owner notification letters were mailed March 31, 2022. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 44S3.
