What to know before buying: Audi RS3

From 3 press tests · updated 11/10/2026

What the reviews say

• The 2.5-litre five-cylinder TFSI produces 400 hp; the latest RS3 reaches 100 km/h in 3.8 seconds.[1][2]
• The all-wheel-drive torque splitter varies drive between the rear wheels, improving cornering and grip in poor weather.[1][2]
• Seven drive modes can make the RS3 calmer for daily use or sharper by sending more torque to the rear axle.[2]one source
• The Competition Limited version has adjustable coilover suspension, a stiffer rear anti-roll bar and ceramic brakes.[1]one source

Typical faults

• The direct-injected DAZA can accumulate carbon on its intake valves, causing rough idle, weaker throttle response and performance loss.[3]one source

  DAZA

• Heat, hard driving and tuning can contribute to turbo, diverter-valve or boost-system faults; signs include noises under load and inconsistent power.[3]one source

  DAZA, DNWA

• High oil consumption, especially with ethanol or tuning, can be linked to PCV failure, excessive crankcase pressure, oil blow-by and piston-ring wear.[3]one source

  DAZA, DNWA

• Dirty or mismatched injectors can cause long cranking, misfires and uneven fueling; the high-pressure pump can also be vulnerable on tuned cars.[3]one source

  DAZA, DNWA

• Newer 8Y RS3s have shown cold-start whine rising with RPM and transmission overheating, potentially involving the DSG pump, cooling or mechatronics.[3]one source

Which engine and version to take

• The 400 hp 2.5-litre five-cylinder TFSI combines a 3.8-second 0–100 km/h time with a seven-speed dual-clutch gearbox and quattro.[1][2]

What to avoid

• Treat tuned or ethanol-fueled cars cautiously: the source particularly links them to oil-use, PCV, injector and high-pressure-pump problems.[3]one source

What to check at the inspection

• From cold, check idle quality, cranking time, misfires and throttle response; these can point to carbon buildup or fuel-system trouble.[3]one source
• During the test drive, listen for noises under load and check for consistent power; lost boost may indicate a leak, diverter valve or turbo fault.[3]one source
• Check the oil level and top-up history, inspect the PCV system and watch for black exhaust smoke, which may appear after internal damage.[3]one source
• On a cold 8Y, listen for a high-pitched whine from the driver-side engine bay that rises with RPM, and check for transmission-overheat warnings.[3]one source
• Test fuel pressure and injector operation, especially on tuned or flex-fuel cars; warning signs include long cranking, vibration, misfires and a faint whine.[3]one source
