Hello my name is ***** ***** you add the list on this site for me to review please?
Ok so this year has a M54 engine. You say that it smells like it is running rich? Try to connect a fuel pressure gauge to the fuel rail. Try to shut off the vehicle and then pinch off the pressure and return line of the fuel rail and make sure you do not have a injector/s leaking down. This will cause exactly what you are describing. Also what it the coolant temp reading this too will cause a rich issue if the temp is reading cold but within the spec. There is also an issue with lifters sticking on this engine when the get higher mileage, also could be a running issue. Are the front and rear O2 Sensors sweeping? If you have one stuck or the cats are blown out you will get weird codes and possible running issues. Let me know what you find.
The coolant temp would have to be read with a diagnostic reader and it should be around middle of the temp gauge and read about 190 degrees or so. Also is the oil level correct? The white smoke is oil so we need to make sure the oil is not over filled as well.
Yes not a problem. Talk to you then.
I am just locking the question, just reply when you have time after the checks.
