Caching

Carbon buildup on intake & valves. Problem start a year ago, start giving me some white smoke when first started. Purchase Mercedes recommended part to add to fuel. It worked and stop using product know returned, worse than b4. I'm on my way to dealer to order sufficient to treat for the next 6 to 8 months. If you have any Carbon deposit on valves or intake 1 treatment isn't clean Carbon deposits you will need to keep treatment for a year or so. Then treat every month after that. M156 6.2 engine.

Check your coolant level, be sure it is not going down.
