# Service bulletin Campaign Circula

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10124784
- Published by NHTSA: 2017\-12\-05
- Manufacturer's number: Campaign Circula

## NHTSA's 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.
