- Summary
- For certain 2008 model year Audi S5 vehicles, the 24AY Emissions Service Action replaces the 24AM Emissions Service Action. The 24AY action must be completed on all vehicles regardless if 24AM was completed or not. Some vehicles may experience random cylinder misfires during cold start or warm up which could cause the Malfunction Indicator Light (MIL) to come on. If the MIL is on because of this issue, a vehicle will not pass an IM (emissions) inspection. Install improved engine control module (ECM) software.
