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 2009-2024 Audi R8 Carbon-Ceramic Brake Rotor Edge Chipping/Cracking and Melted Pad Wear Sensors?

R8s optioned with carbon-ceramic brakes (CCB) suffer edge chips and cracks in the rotor friction ring, and after hard or track use the pad wear sensors and pad backing adhesive melt. Because ceramic material chips rather than wears, a chipped rotor edge is grounds for replacement… Repairs typically run $600-$17,000. Severity: medium.

The R8 Spyder roof sequence is controlled by multiple position sensors and microswitches (on the hydraulic rams for the rear lid and the 'bat-ear' panels) plus a rear power window that must complete its own cycle. When a sensor or microswitch fails, the controller stops mid-seque… Repairs typically run $400-$3,000. 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.
