2013 Audi S8

Issue: 
On certain vehicles, the oil strainer for the turbocharger oil supply could get blocked. If this happens, a turbocharger could fail. This could cause loss of engine power and/or cause the engine to stall. 
Note: This problem could cause different warning messages to display or the engine oil warning light to turn on. 

Safety Risk: 
A sudden loss of engine power could increase the risk of a crash. 

Corrective Actions: 
Audi will notify owners by mail and instruct you to take your vehicle to a dealership to replace the oil strainer for the turbocharger oil supply. The dealer will also inspect and document the performance of the boost pressure system and change the engine oil.

Issue: 
On certain vehicles, the engine compartment seal may become loose over time and fall into the engine compartment. If this happens, the seal could contact a hot surface in the engine compartment.
 
Safety Risk: 
A rubber seal that falls onto a hot surface could cause a fire.

 Corrective Action: 
The company will notify owners by mail and instruct you to take your vehicle to a dealer to install a retaining plate on the engine compartment seal.

Issue: 
On certain vehicles, the fuel line to the high-pressure fuel pump could leak. This may cause a gasoline odour or leak. 

Safety Risk: 
Leaking fuel, in the presence of an ignition source, creates the risk of a fire. 

Corrective Actions: 
The company will notify owners by mail. Owners will be instructed to take their vehicle to a dealer for repair. A fuel pressure damper will be installed in the low pressure fuel supply located inside the fuel tank.

On certain vehicles, the fuel supply line for the high pressure fuel pump may become porous over time. This could cause a fuel smell or a fuel leak, which in the presence of an ignition source, could result in a fire causing property damage and/or personal injury. Correction: Dealers will replace the fuel line.

On certain vehicle the sunroof may have been manufactured incorrectly and could be susceptible to breakage.  Sunroof glass panel breakage, while the vehicle is in motion, could cause driver distraction, which could result in a crash causing property damage and/or personal injury.  Additionally, broken glass inside the vehicle could pose a risk of injury to vehicle occupants.  Correction: Dealers will replace the sunroof glass panel.
