Carbon Cleaning Audi A5 (2013 B8.5) | Reassembly! [Part 3]

Welcome to Part 3 of my 3-part carbon cleaning series on a 2013 (B8.5) Audi A5. In this video, I’ll walk you through reassembly! I'll start with the new injectors, installing the fuel rail, both lower and upper intake manifolds with all new gaskets and finish it off with new plugs and coils!

If you own a 2.0T Audi (A4, A5, A6, Q5, or other models with the EA888 engine), you know carbon buildup on intake valves is a common issue. Over time, it robs performance, fuel efficiency, and smoothness. This series will show you how to tackle it — from teardown to cleaning to reassembly.

Best of all, I'll show you that this is something you can tackle at home - no need to take it to the dealership or an independent shop. Save some money, Raise your DIY confidence and let's get to it!

🔧 What you’ll see in this video (Part 3):
