Walnut Blasting for TSI Direct Injection
Direct injection TSI engines cannot clean intake valves with fuel — carbon builds up over 60,000–80,000 km of KL city driving. Symptoms: rough idle, hesitation, reduced economy. Walnut blasting removes deposits without removing the cylinder head. At 4M Car Care this is done at operating temperature followed by VCDS idle adaptation reset.
