Tl the contact owns a 2013 BMW X5. The contact stated that the check engine warning indicator illuminated. The vehicle was taken to tom bush BMW jacksonville (9875 atlantic blvd, jacksonville, FL 32225, (904) 371-4790) where it was diagnosed that the intake manifold, swirl flap, and air cooler needed to be replaced; however, the contact declined the repairs.

Oil leak from the valve cover gasket gets into the hot manifold causing a burning oil smell and smoke getting into the cabin through the ac vents causing a major safety issue.
After 65,00 miles while driving the engine locked up and will not run. The car did not have an oil leak or excessive consumption, but heavy black soot was emitted from the tail pipes enough that has turned the rear tailpipe surround black.
