BMW 330xi Problems

Oil Leaks From Engine Area

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.

Front Outer CV Boots May Tear and Leak at 60,000 Miles

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.

Coolant Loss Due to Leak from Expansion Tank

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.

My Fiance and i have had sevral problims with out bmw... it drives me crazy
My 330XI beats every car I've ever owned by a longshot; audi coupe, A6, etc. I have never driven anything that felt so glued to the road, yet didn't transfer the little bumps through to the driver. Solid everywhere, torque everywhere, go anywhere. Love this BMW.
