Mercedes-Benz GLE Carbon Buildup — V6/Inline-6 Cleaning Malaysia
GLE M276 and M256 direct injection engines develop carbon deposits on intake valves. Walnut blasting at 60,000–80,000 km restores performance. SUV carbon cleaning costs and process in Malaysia.

All GLE engines use GDI (direct injection) — intake valve carbon buildup applies to all variants including the V6 and V8. On larger engines the buildup can be heavier due to greater crankcase breathing volume. Walnut shell blasting is the correct method. Expect higher cost than 4-cylinder due to more intake ports.
