Recalls: Audi D4 S8
2017 model year Audi D4 S8: airbags and pre-tensioners may not deploy as intended
In March 2017, a recall was issued for 2017 model year Audi D4 S8 vehicles. In these vehicles, irregularities in the mix ratio of the igniting agent in some airbag units or seatbelt pre-tensioners could lead to the airbags or belt pre-tensioners not deploying in the event of a collision. As such, the risk of injury for the front occupants of the vehicle was increased. For the VINs of the recalled vehicles, please see PRA 2017/15964.
2010-13 model year Audi 4H S8: loss of power steering
In February 2020, recall campaign 48O8 was issued for 2013-13 model year Audi 4H S8 vehicles. In these vehicles, the hydraulic return hose for the power steering system may leak in the following conditions:
- The power steering was under a high pressure load;
- The steering was at full lock; or
- An uneven road surface caused heavy vibrations.
If the power steering hose leaked, the vehicle may experience reduced or complete power steering failure. Hydraulic fluid may also leak into the engine compartment and it could ignite if it came into contact with hot components. These circumstances increased the likelihood of a collision, thereby increasing the risk of injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see PRA 2020/18153.
2012-17 model year Audi D4 S8 4.0 TFSI: engine bay seal could warp or come loose
In December 2020, recall campaign 51G6 was issued for 2012-17 model year Audi D4 S8 and S8 plus vehicles that had 4.0-litre TFSI V8 petrol engines. In these vehicles, the engine bay seal may become warped and come loose. If this occurred, engine vibrations may result in the engine bay seal making contact with hot components in the engine bay. This condition could cause scorching of the seal or other components, resulting in fire or smoking from the engine bay. For the VINs of the recalled vehicles, please see PRA 2020/18651.

2013-14 Audi D4 S8 4.0 TFSI: DTC P0011 and/or P0021
In July 2016, Audi issued Technical Service Bulletin 01 16 71 2041097/2 for 2013-14 model year Audi D4 S8 vehicles that had 4.0 TFSI engines. According to the bulletin, these vehicles may exhibit the following symptoms:
- Illumination of the Malfunction Indicator Light (MIL);
- Irregular or rough running; and,
- The following Diagnostic Trouble Codes (DTCs) may be stored in the engine control module (ECM), J623:
- DTC P001100 – camshaft position (bank 1) timing over-advanced or system performance); or,
- DTC P002100 – camshaft position (bank 2) timing over-advanced or system performance.
These symptoms were attributed to the filter element on the camshaft adjustment control valve becoming loose. However, there was no consequential damage from loosened particles in the oil circuit since they would be collected by the oil filter. To fix, a new O-ring (part number WHT002789) was to be fitted to a new control valve (part number 06E109257S) and the hex collard bolt was to be replaced with a new bolt (part number N 91211101) and tightened to 5 Nm.
