Cold start rattle on your Audi S4? Don’t ignore it.
We just had a 2012 S4 with rough starts and no check engine light—the issue was carbon buildup choking the secondary air system.
If your S4 sounds rough for a few seconds on startup, it’s not normal—it’s a warning. We have the factory Audi tool and pressure washer to properly clean the secondary air ports and get your Audi running properly. https://dartauto.com/blog/audi/rough-cold-starts-in-a-2012-audi-s4-the-hidden-carbon-buildup-problem
