2003 BMW 330xi ProblemsBurning Smell or Oil Drips on the Ground Due to Engine Oil Leak
Valve cover gasket leaks are common after 60,000 miles. Symptoms will include oil drips under the vehicle and burning oil smell from the engine compartment.
After 60,000 miles, the front outer half-shaft boots tend to tear and leak grease. In most cases, only the boot will have to be replaced; however, if it is not repaired soon enough, the half-shaft may need to be replaced. The front outer boots are put under heavy stress because of their involvement with the suspension when making turns.
An engine coolant leak may develop from the expansion tank resulting in engine overheating. When a cooling system component fails the entire cooling system should be inspected. It is not uncommon to find additional component have failed or are leaking.
Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

While driving my BMW randomly started cutting out, it was very jerky and sputtered me to the side of the road. Now when I start it it struggles to start and once going it will cut out a few times and die. What could be causing this and how do I fix it?
When I use the heat, cold air comes from the vents. My car is not overheating, so I am wondering what it could be, besides a thermostat.
