Professional Carbon cleaning (Walnut blasting) at Mechalex

What is Walnut blasting?

Audi Gearbox Service

Over time, carbon deposits build up inside your engine (see above), particularly on the intake valves, intake manifold, and combustion chambers. This can negatively impact engine performance, fuel efficiency, and emissions. This process is accelerated with modern engines using exhaust gas re-circulation valves (EGR's) to improve emissions.


Modern direct injection engines are especially prone to carbon buildup since fuel is injected directly into the cylinders, bypassing the intake valves where traditional fuel spray would help keep them clean. Without proper maintenance, this can lead to:

πŸš— Reduced engine performance
β›½ Lower fuel efficiency
⚠️ Rough idling and misfires
πŸ”§ Check Engine Light activation
πŸ’¨ Increased emissions

To restore your engine’s efficiency and performance, professional carbon cleaning is essential.
