Hello. Can you figure from this video what's the problem?
Great video. I've been trying to figure out the problem with my C230 Mercedes as it cranks but it won't start eventually, or it starts as if there is a misfire in one cylinder. This would happen intermittently, so it was really difficult to find the problem. Run code checks, and there are no fault codes. Making a visual inspection, I realized the short hose connecting the airbox to the supercharger was loosen, as the bracket wasn't positioned correctly which was sufficient to allow more air to be sucked into the engine while cranking. Once the engine started, everything worked just fine and no fault codes were found. Just had to readjust the bracket, now it's all good.
I have a 2007 Mercedes Benz s550 no crank but display working let me know if you got any suggestions!
