What is the 2008-2023 Audi R8 Ignition Coil Pack Failure Causing Misfires?

The coil-on-plug ignition coils on both the 4.2 V8 and 5.2 V10 are a recurring weak point, often failing between 50,000 and 80,000 miles. A failing coil produces a weak or inconsistent spark, triggering cylinder misfires, rough idle, hesitation and a check-engine light. Owners fr… Repairs typically run $500-$1,600. Severity: medium.

What is the 2008-2023 Audi R8 Direct-Injection Fuel Injector Failure?

The FSI direct-injection injectors shared across the VAG family (Audi/VW/Porsche) are a documented R8 failure point. Injectors can stick open or closed; a stuck-open injector dumps raw fuel into the cylinder and can wash down the bore, while a stuck-closed injector starves the cy… Repairs typically run $1,500-$4,000. Severity: medium.

What is the 2008-2023 Audi R8 In-Tank Low-Pressure Fuel Pump Failure Causing Whine, Hard Starts and Stalling?

The R8's direct-injection fuel system depends on an in-tank low-pressure lift pump feeding the engine-mounted high-pressure pumps (two HPFPs on the 5.2 V10). The in-tank pump, shared with the Lamborghini Gallardo/Huracan on V10 cars, wears and loses delivery volume, producing a h… Repairs typically run $1,400-$3,700. Severity: medium.

What is the 2008-2015 Audi R8 Intake Manifold Tumble-Flap Vacuum Actuator / Solenoid Failure Causing Rich Running and Rough Idle?

Both R8 FSI engines use vacuum-operated intake manifold flaps (tumble flaps) that close at low load. On Gen 1 cars the vacuum solenoid under the manifold burns out (often in the flap-closed position), the 90-degree check valves and the T-hose near the throttle body crack, and car… Repairs typically run $150-$2,500. Severity: medium.

What is the 2008-2015 Audi R8 Oil Leak Between Engine and Gearbox: Rear Main Seal / Transmission Input-Shaft Seal (4.2 V8)?

Gen 1 V8 owners report oil pooling at the bell-housing joint between the engine and the gearbox. The source is either the crankshaft rear main seal (often driven by a clogged PCV raising crankcase pressure) or the transmission input-shaft/shift-mechanism seal on the gearbox side;… Repairs typically run $3,000-$17,000. Severity: medium.

What is the 2008-2015 Audi R8 Carbon Fiber Sideblade and Trim Clear-Coat Peeling?

Owners of R8s with the carbon-fiber sideblades (and other exposed carbon trim) report the factory clear coat clouding, hairline-cracking and peeling, especially around edges and mounting points. The consensus cause is thin/insufficient UV protection on the factory finish; matte c… Repairs typically run $300-$1,500. Severity: low.

What is the 2008-2015 Audi R8 Exhaust Valve Vacuum Actuator Diaphragm Failure Leaving Exhaust Stuck Loud or Quiet?

Gen 1 R8 mufflers use vacuum-canister actuators to open the exhaust bypass valves in Sport mode or above a set RPM. The rubber diaphragm in the actuator canister and the control solenoid fail from heat, or the valve pivot seizes, so the valves stay permanently open (loud at all t… Repairs typically run $90-$800. Severity: low.
