Known issues on the 1998 A8. Three recalls are on federal record for this model year. The first covers vehicles with the 5-speed automatic transmission: the locking cable can shift out of position over time, letting the shifter move out of Park even without the key in the ignition, so the vehicle can roll away without warning. The second covers the steering tie rod seals, which can let moisture and dust into the swivel bearing mechanism; the bearing can wear over time and diminish steering control. The third covers the driver-side frontal air bag inflator, which may lack phase-stabilized ammonium nitrate propellant and can absorb moisture, causing the inflator to explode or the air bag to underinflate. Owners have filed 7 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a transmission shift-lock inspection to a steering linkage check or an air bag system diagnosis, it keeps you on the OEM procedure and the correct specification for your specific 1998 A8.
