Common BMW Problems and Repairs

BMW Car

Reliability and high level of performance are the hallmarks of German car manufacturer BMW, with most customer surveys supporting its reputation. However, even the best design is susceptible to malfunctions, some minor while others of chronic nature.  

Regular service and tune-ups will prolong the engine's lifespan. But as the miles start racking up, wear and tear will inevitably cause issues under the hood. Responsible BMW owners in Brandon, FL, are proactive, identifying potential complications ahead of time and reducing unplanned costly trips to the mechanic.

Keep reading to learn the most frequent BMW repair issues.

Oil Leaks

A stain on the driveway is a sure sign of a leak in the oil system. Alternative indicators of oil leakage are the smell of burning oil or white smoke from the exhaust, signaling the mixing of oil with other fluids and gas. 

There are several possible reasons for this situation, such as leaky valve cover gasket, camshaft seals, and even a faulty fuel pump.

Neglecting oil leaks can result in serious internal damage because of increased friction between the parts. A professional can properly diagnose the root cause and solve the problem.

Faulty Ignition Coils

Sluggish acceleration and power lags are symptoms the engine isn't working right. Activating the check engine lights on the dashboard is another sign pointing toward a problem. 

The good news is that ignition coils are probably at fault. It's a rather inexpensive part, with specific service life requiring a scheduled change. 

If you catch this issue in time, it can get fixed cheaply and fast. But neglecting the problem can have costly consequences.

Electrical Problems

Electrical problems are a trait shared by all modern cars, considering wiring crisscrosses the entire vehicle. In BMW cars, the most frequent electrical problems are:

  • Faulty wipers 
  • The cooling fan is running constantly
  • Unresponsive turn signal, and more

The electric issues will vary depending on the model.

Water Pump Malfunction 

The drive for innovation made BMW incorporate an electric water pump before its competitors, which used a water pump driven by a belt. BMW's decision benefited drivers with reduced engine noise, simultaneously not burdening the engine with the extra power to drive the belt. 

The issue is that they tend to perform poorly after some time. Electric water pumps typically malfunction at 60,000 miles and should be replaced with the thermostat to avoid overheating issues.   

Issues With the Fuel Pump

Owners of popular BMW models have experienced problems with the high-pressure fuel pump. The consequences of this problem include poor acceleration, the engine starting to stutter during high speeds, and not turning on at all. 

Engines operate with two fuel pumps, a low-pressure pump that extracts gasoline from the storage tank, and a high-pressure pump that distributes gas into the combustion chamber. When the high-pressure pump is not working correctly, the performance will be subpar, and replacing it is the only option.
