Known issues on the 2018 S5. Two recalls are on federal record for this model year. The first covers the front passenger air bag inflator module: oxidation on the Passenger Occupant Detection System connecting cable can cause the software to misdiagnose a malfunction and disable the passenger air bag, increasing the risk of injury in a crash. The second covers the seats: the cable connecting the seat heater to that same Passenger Occupant Detection System can develop a contact fault, again causing the system to misdiagnose a fault and disable the passenger air bag. Owners have filed 26 complaints for the year. The factory diagnostic and repair procedures behind that PODS wiring and connector work are here.

Whether you're tracing a passenger air bag fault back to the PODS connector or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2018 S5.
