From the late nineties to around 2006, petrol engines used a secondary air pump to blow fresh air into the exhaust on a cold start, so the catalytic converter reaches operating temperature faster.

22V471000AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULEAIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE1 July 2022 · NHTSA (USA)Volkswagen Group of America, Inc. (Audi) is recalling certain 1998 Audi A8 and 1997-1998 Audi A4 vehicles equipped with Non-Azide Driver air bag Inflators (NADI) that do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflator may absorb moisture, causing the inflator to explode or the air bag cushion to underinflate.
Risk: The inflator could explode during air bag deployment, resulting in metal fragments striking the driver or other occupants. An underinflated air bag may not properly protect the occupant. These scenarios increase the risk of serious injury or death.
Remedy: Dealers will replace the driver's air bag inflator with an alternative inflator of a different design, free of charge. Owner notification letters were sent September 21, 2021. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 69BT. The vehicles in this recall were mistakenly omitted from recall 20V-056. All vehicle owners have already been notified by mail and informed that the remedy is available.

Information, not an expert opinion
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
- A fault on the list does not mean the car you are looking at has it.
- A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
- You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
