The second-generation R8 moved to an all-aluminium and carbon-fibre Audi Space Frame, dropped the V8, and became a V10-only model. Power ranges from 540 hp (V10) to 620 hp (V10 Performance). The 5.2 FSI V10 is shared with the Lamborghini Huracan and remains one of the most robust naturally aspirated supercar engines in production. It is offered exclusively with the 7-speed S-tronic dual-clutch gearbox. Production ended in March 2024.· more· less

Buy if: You want a reliable supercar with everyday usability, proven V10 durability, and can budget for expensive ancillary repairs when they arise.
Avoid if: You cannot absorb potential repair bills in the €3,000-8,000 range for suspension and transmission, or the car has been heavily tracked without documented maintenance.
MagneRide dampers leak fluid over time, all will eventually need replacement or rebuild · more· less
The R8 Type 4S uses the same magnetorheological damper technology as the first generation. Ferromagnetic fluid inside the dampers degrades and eventually leaks past the seals. Failures are commonly reported between 40,000 and 80,000 km, though cars that sit for extended periods are particularly vulnerable as the fluid settles and damages seals. Symptoms include a damp or oily appearance on the damper body, loss of ride quality differentiation between comfort and sport modes, and eventually thumping or bottoming out over bumps. OEM replacement costs approximately €1,400-1,600 per damper (€5,600-6,400 for all four) plus labor. European rebuild services offer regeneration at approximately €250 per damper (€1,000 total), which is a popular cost-effective option. Aftermarket coilover conversions are also available from €2,500-4,000. Audi classifies dampers as wear items, so warranty coverage is typically denied even on newer cars.
S-tronic clutch pack wear (DL800)
€5,000 - 9,0002 of 7
Dual-clutch packs wear faster with track use or aggressive low-speed driving · more· less
The Type 4S uses a DL800 7-speed wet dual-clutch S-tronic gearbox, which is significantly more durable than the first-generation's R-tronic. However, the clutch packs still wear over time, particularly on cars used on track or driven aggressively in stop-and-go traffic. Clutch life varies enormously depending on driving style: conservative street driving can see 80,000-120,000 km, while tracked cars may need replacement by 40,000-60,000 km. Symptoms include jerky low-speed engagement, slipping under hard acceleration, and transmission warning messages. Replacement requires removing the transaxle, with total cost typically €5,000-9,000 at specialists. A gearbox oil service every 40,000 km (approximately €400) helps extend clutch life. Some R8s built between October 2015 and November 2017 were subject to a recall for a gearbox ventilation hose that could leak oil under high-speed driving, potentially causing a fire risk.
AC compressor seizure
€2,500 - 4,5003 of 7
Compressor seizes when not used regularly due to dried-out internal seals · more· less
Like the first generation, the AC compressor relies on oil in the refrigerant for internal lubrication. If the AC is not used regularly, seals dry out and the compressor can seize. The V10 layout in the 4S allows compressor access without engine removal (unlike the V8 first-gen models), reducing labor to approximately 8-10 hours. Dealer replacement typically costs €3,500-4,500, while independent specialists using aftermarket Denso compressors can bring the total to €2,500-3,000. When the compressor fails, the entire system must be flushed to remove metal debris. Prevention: run the AC for 10-15 minutes monthly, even in winter, and have the system recharged annually if the car is used infrequently.
Carbon buildup on intake valves
€1,300 - 1,8004 of 7
Direct injection causes carbon deposits that restrict airflow and affect performance · more· less
The 5.2 FSI uses direct fuel injection, meaning fuel does not wash over the intake valves. Carbon deposits accumulate over time, causing rough idle, hesitation, and reduced power. Walnut blasting is the standard remedy, recommended every 40,000-60,000 km depending on driving style. The V10 layout means 10 cylinders must be cleaned, pushing costs to €1,300-1,800 at a specialist. Short trips and gentle driving accelerate carbon buildup because the engine does not reach sustained high temperatures. An oil catch can installation (€200-400) helps extend cleaning intervals. While this is somewhat predictable, the interval varies significantly based on driving patterns, and neglecting it eventually triggers misfire codes and noticeable power loss.
Ignition coil failure
€300 - 6005 of 7
Coils degrade from heat stress in the mid-engine bay, causing misfires · more· less
The V10's ignition coils are subject to significant heat soak in the mid-engine compartment. Over time, insulation degrades and coils fail, causing misfires on individual cylinders. Symptoms include rough running, check engine light, and misfire fault codes. Individual coils cost €15-30 aftermarket or approximately €50 OEM. Since the V10 has 10 coils and they tend to fail in groups, most owners replace all 10 preventively when one fails, bringing total cost to €300-600 including labor. The repair itself is straightforward as the coils are readily accessible. This is a well-known maintenance point for the 5.2 FSI across all applications.
Engine mount deterioration
€3,000 - 5,0006 of 7
Hydraulic engine mounts degrade over time, requiring engine-out replacement · more· less
The R8 uses active hydraulic engine mounts to isolate vibration from the high-revving V10. These mounts have a finite lifespan and typically begin to deteriorate after 8-12 years or 80,000+ km. Symptoms include increased cabin vibration at idle and a noticeable harshness during acceleration. The replacement itself is not complex, but the engine must be removed to access the mounts on the V10 models, resulting in 20+ hours of labor. Total cost is typically €3,000-5,000 at an independent specialist. This is more of a long-term aging issue than an acute failure, and many owners live with mild mount wear indefinitely.
Battery drain when parked
€200 - 5007 of 7
Complex electronics draw 40-75 mA constantly, draining battery within 1-2 weeks · more· less
The R8's extensive electronic systems draw significant power even when parked. The parasitic drain of 40-75 mA will flatten a healthy battery within 7-14 days of inactivity. This is a characteristic of the platform rather than a defect. Cars that sit for extended periods frequently need jump starts, which can stress the battery and alternator. The solution is straightforward: keep the car on a quality trickle charger (CTEK MXS 5.0 or similar) when not in use. Battery replacement costs €200-500 depending on brand. The drain can be exacerbated by aftermarket accessories, faulty MMI modules, or alarm systems that do not enter proper sleep mode.
Robust engine, but ancillary systems carry supercar-level repair costs
The 5.2 FSI V10 in the Type 4S is widely regarded as one of the most reliable supercar engines ever produced, shared with the Lamborghini Huracan and proven across hundreds of thousands of kilometers. The engine itself is not the concern. Instead, ownership costs center on magnetic ride suspension (which will eventually leak), carbon buildup on intake valves (requires periodic walnut blasting), and the S-tronic gearbox (durable but expensive to service if clutch packs wear). The 4S eliminated several first-generation headaches: no more R-tronic clutch issues, no frame crack risk, and no problematic coolant expansion tank placement. Cars with documented service history and regular use are significantly less expensive to own than those that have been garaged and driven infrequently.
Service history
Complete Audi dealer or authorized specialist records essential. Verify oil changes at least annually and gearbox oil service history.
Tires
Check tread depth, age (date codes), and uneven wear. Staggered setup means rears wear faster. Budget for high-performance tires.
Cold start
Start engine completely cold. Listen for unusual sounds, rough running, or individual cylinder misfires during the first 30 seconds.
Test drive
Minimum 30 minutes including highway speeds. Get the engine and gearbox fully up to temperature to reveal any heat-related issues.
Specific for this vehicle
Inspect magnetic ride dampers for leaks
Check all four damper bodies for oil misting or wetness. Any oil visible means replacement or rebuild is needed. Toggle between comfort and sport modes and verify the ride quality changes noticeably.
Test AC system thoroughly
Run the AC on maximum cold for at least 10 minutes. Listen for unusual compressor noises or grinding. Failure to cool indicates a seized or failing compressor.
Check for carbon buildup symptoms
During the test drive, note any rough idle, hesitation, or momentary misfires. Ask when the last walnut blasting was performed. If unknown or over 50,000 km ago, budget €1,300-1,800.

Drive for 20+ minutes and test gearbox at low speed
Feel for jerky shifts, hesitation, or clunking during slow-speed maneuvering and parking. These are early signs of clutch pack wear in the S-tronic.
Scan for fault codes with VCDS or OBDeleven
A full diagnostic scan will reveal stored misfire codes, transmission faults, suspension warnings, and VVT solenoid issues that may not trigger dashboard lights.
Check for gearbox ventilation hose recall (Oct 2015 - Nov 2017)
Verify with Audi using the VIN that the gearbox ventilation hose recall has been completed on affected build dates. Oil leaks from the gearbox during hard driving pose a fire risk.
Verify track use history
Track use accelerates clutch, brake, and tire wear dramatically. Ask about track days and check for evidence of track-specific modifications or brake dust patterns.
