What is GDI intake valve carbon buildup?
In GDI (gasoline direct injection) engines — all modern Audi TFSI, VW TSI, BMW N-series, and Mercedes CGI engines — fuel is injected directly into the cylinder. The intake valves never see fuel spray and can't self-clean. After 40,000–60,000 km, the backs of the intake valves are coated with hard carbon that restricts air flow and causes misfires and rough idle.
What is walnut blast cleaning and how much does it cost?
Walnut blast is the gold-standard method for GDI carbon cleaning — crushed walnut shells are blasted through the intake ports under pressure, stripping the carbon from valve backs without damaging the soft aluminium. GarageNation performs walnut blast for ₹12,000–₹30,000 depending on engine type (4-cyl vs 6-cyl) with before/after bore-scope photos.
Is gdi intake valve carbon clean covered by car insurance in India?
