Walnut Blasting for VAG Engines: Carbon Cleaning for Peak Performance | Novo AVS Sydney

If your Volkswagen, Audi, Škoda or CUPRA is hesitating under throttle, idling roughly, or showing misfire codes, there’s a good chance carbon build-up is choking your intake valves. At Novo AVS, we offer precision walnut blasting for VAG platforms, restoring power and drivability.

What Is Walnut Blasting?

Walnut blasting is the industry-standard method for cleaning intake valves in direct-injection engines. We blast finely ground walnut shells into the intake ports under controlled pressure, safely removing hardened carbon without damaging your cylinder head.

Why Carbon Build-Up Happens on VAG Engines

Modern EA888 Gen 3/4 and other MQB-based direct-injection engines no longer wash the intake valves with fuel. Instead, oil vapour from PCV systems and EGR by-products accumulate over time—forming a thick, abrasive carbon layer that restricts airflow.

Common Signs of Carbon Build-Up

  • Rough idle or engine vibration at low RPM

  • Flat throttle response or hesitation

  • Poor fuel efficiency

  • Intermittent misfires or check engine lights

  • Diagnostic codes like P0300–P0304

If you’re tuned, running upgraded intakes, or doing short urban trips, your car is especially at risk.
