Lower Engine Leaks Oil
If you smell oil burning or see oil dripping under the car, then there’s a good chance your BMW has a valve cover gasket leak. This is especially common when the vehicle has more than 60,000 miles. Some owners notice this problem only when starting the car. If you only have to replace the valve cover gasket, it will cost you around $300 – $600.
If this problem is not detected early, oil can get into the plugs, sensors, and ignition/engine coils which can lead to misfiring. The cost to repair at this stage could be over $3,000. A good extended warranty will cover this cost.
BMW Mirror Folding Problem
The side mirror, especially on the driver’s side, can fold in or out spontaneously. Sometimes it returns to the neutral position, but in other cases you have to move it by hand. This could happen even after minor impact to the mirror.
There is a special ring inside the mirror that senses position. When this ring wears down or breaks, it must be replaced. This can cost you $500 to $700.
Heat & Air Conditioner Fan Malfunction
This problem is more common after 100,000 miles. The fan might work on-an-off or at a very slow speed. Some owners mistake it for an air conditioning issue, but the culprit is more likely the blower final stage fan resistor. Replacement cost is $400+.
Power Steering Fluid Leak
If you see fluid, but not oil or water, leaking from below, it could be power steering fluid. Many times multiple power steering hoses must be replaced, and the cost is around $450 for parts and labor.
AC Related Vibration
If you hear a buzzing or feel an unusual vibration in the steering wheel when the AC is running, your BMW 328i most likely needs an air conditioner refrigerant charge. It may also be worth it to ask the mechanic to check for leaks in the system. The typical cost for a Freon charge is around $150 – $250.
Low Coolant Light Comes On
This might just be a simple matter of adding coolant, but make sure there is no leaking from the 328i’s underside. If there’s a leak, it could be from the water pump. This problem is more common for vehicles over 90,000 miles. Make sure the entire coolant system is checked since at this stage, multiple leaks can be present. A new water pump will run you about $900, parts and labor.
