AUDI Walnut Shell Blasting FAQ
1) What is walnut blasting and why do Audis need it?
Walnut blasting is a non-metallic media clean that safely removes intake-valve carbon on direct-injection engines. Many Audis develop deposits because fuel doesn’t wash the valves.
2) How often should I do it?
Typical interval is 80,000–120,000 km, or sooner if you notice misfires, rough idle, or power loss. We confirm need with a borescope before recommending service.
3) Is walnut media safe for my engine?
Yes. Crushed walnut shells are soft, won’t damage aluminum, and are vacuum-removed. We block ports, control media flow, and verify each cylinder with photos.
4) How long does it take and what does it cost?
Most jobs are same day depending on model and access. After inspection we provide a written estimate; pricing varies by engine and required gaskets/parts.
5) Do you service more than Audi?
Absolutely. We’re the best mechanic near you for auto repair and service on all makes and models—European, Asian, and domestic.
