Great content! Have one question, w220 s350 gasoline, many people complain of 20 liter per 100 km fuel consumption problem. They try to replace maf and oxigen sensors, spark plugs, fixing the brakes in case they block some wheel, put better octane gasoline, replace tires and keep them inflated to spec and much more with no effort. Have you ever heard of this problem and a possible fix?

Hi ! That's sounds like a lot of unnecessary upgrades .Yes I've heard about it and in all the situations there is one thing in common: No Diagnosis. That's what I try to show in this (boring) videos on how to test components and show how they work . than you might recognise easier what's the issue . There can be many reasons; For example if there is a unrealistic signal on a sensor without triggering a fault code than the fuel delivery would be affected . so a scan tool and learning the live data interpretation is the most important thing . and is not easy I am still learning as well .

W220 S500 - replaced fuel pump, fuel filter, and fuel relay on the rear Sam and my car still dies after it turns over. It once idled longer when I got it to turn over and held throttle above 2k and after it settled it idled just fine. When I hit the gas a little it died immediately. Help?

the best in this situations is to check the live data or freeze frame ( if available ) first , before doing any work ...
