Mercedes-Benz GLE — 积碳清洗
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.
