BMW 330xi Problems

Burning 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.

Front Outer CV Boots May Tear

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.

BMW 330xi Reviews

I looked specifically for a 2004-2006 330XI for over 4 months knowing I wanted a real spare tire. Found mine with only 67K miles on it, have 98K now. Previously had a 1999 M3, Infinity G35 and a 2008 M5. All were horrible in the rain, sleet & snow. These handle like a dream especially in snow lower than 8 inches and gets decent gas mileage. Wish it had a little more leg room in the rear bu...
Traded 2002 Maxima SE (215K miles) for 2005 330xi (105K miles). The BMW is great, the Nissan was overall a better car dollar for dollar. Maxima is a slightly bigger car more comparable to a 5or7 series, so can't comment on the smaller BMW leg room and trunk. Maxima 3.5L was fast, BMW 3.0L is quick. BMW has the edge with AWDrive over FWDrive. The BMW is very solid with tight steering/susp...
