The GL320 had some smells in the cabin that are not supposed to be there so.. In this video I repair the Fuel injector seat on the Mercedes Benz OM642 diesel 3.0Litre v6 turbo diesel. The 2008 GL320Cdi has 195,000 miles on it and this is the third injector to develop this issue. And thankfully it's not been the same one twice. and I have been able to resolve the issue relatively easily every time. I also almost hydrolocked it with carb cleaner..

The Symptoms start with Smell of burnt diesel and smoke and progress to a persistent smell of poorly bunt fuel in the area of the engine.
