Mercedes-Benz GLA Carbon Buildup — GDI Cleaning Malaysia
GLA M270/M260/M264 direct injection engines develop carbon deposits on intake valves from 50,000 km. Walnut blasting or chemical induction cleaning every 60,000 km. Malaysia service costs.

GDI intake valve carbon buildup — identical situation to A-Class and CLA. By 60,000–80,000 km the buildup causes rough idle and reduced throttle response. Walnut shell blasting is the correct method (RM 800–1,200). Inspect at 60,000 km; clean as needed.
