The most common BMW part failures and how to fix them

BMWs are fast, stylish cars, but sometimes, their parts can fail. It is a reality that some parts fail more frequently than others. You can plan if you know you must go over budget for some parts of your car.

Most of the main components that induce some issues are the cost of the suspect and the injectors. It is common for these parts to fail early and last a shorter time than the rest of the vehicle. These problems will cause your car to overheat or make noises that aren’t normal.

Replacement of the broken parts is essential to rectifying the above problems. Maintain your cooling system and suspension, and clean or replace your fuel injectors. This way, your BMW will always be in good condition.

Part failures in BMW vehicles

BMW-mounted cars are unique, high-profile, luxurious, and classy cars. Yet it is clear that even the best cars, such as BMW, may face a situation when some parts fail. Some issues occur due to wear and tear or due to some of the specific design problems. 

1. Water Pump

The water pump is an important component of any BMW’s cooling system. A vehicle has this one to distribute coolants to make the engine run at the recommended temperature.

Common Issues:

  • Electric Water Pump Failure: Current models of BMW employ electric water pumps, which are vulnerable to failure at 60k,000 to 90,000 miles.
  • Overheating: A failing pump can lead to overheating, which may result in major damage to the engine.

Signs of Failure:

  • Engine overheating.
  • Coolant leaks.
  • Dashboard warning lights for the cooling system.

Prevention:

Regular maintenance and early replacement can prevent catastrophic engine overheating. Using high-quality coolant specific to BMWs is crucial.

2. Thermostat

The cold and hot water thermostats work together with the water pump to control the calibrations of the engine temperature. Performance problems or serious damage can occur if a car’s thermostat is defective.

Common Issues:

  • Sticking Open or Closed: A thermostat stuck open makes the engine run too cold; on the other hand, one stuck closed makes the engine run hot.
  • Electronic Malfunctions: Some electronic thermostats are available on the market, and some parts are easily damaged.

Signs of Failure:

  1. Rising or varying temperatures of either the car’s engine or coolant.
  2. Reduced fuel efficiency.
  3. Engine warning light.

Prevention:

When performing normal cooling system maintenance, adjust the thermostat to avoid breakdowns.

3. Ignition Coils

Ignition coils are very important in sparking fuel in the engine. Ignition coils can go bad in BMWs, which is common, particularly with cars with turbocharged engines.

Common Issues:

  • Wear and Tear: Coils wear out, especially when exposed to high-performance engines.
  • Heat Damage: When the engine becomes hot, it may affect some internal workings. More specifically, the ignition coils may be damaged.

Signs of Failure:

  • Excessive smoke emission or stalling of the engine.
  • Difficulty starting the car.
  • Engine warning light.

Prevention:

When an ignition coil fails, maintenance activities include inspection and replacement. This way, you can be assured of using authentic BMW parts approved on the market.  

4. Fuel Injectors

The fuel injectors spray fuel directly into the engine in a very atomized manner. All engines’ performance and efficiency rates are greatly compromised when they fail.

Common Issues:

  • Clogging: In light of this, one can consider that deposits on the fuel, for example, can clog the injectors.
  • Wear and Tear: When high pressure is present, failure consistently occurs.
  • Carbon Build-Up: Especially if it is a direct injection engine, it is common to have this problem.

Signs of Failure:

  1. Decrease or absence of power or acceleration.
  2. Poor fuel efficiency.
  3. Black smoke from the exhaust.

Prevention:

High-quality fuel and clean injectors can extend their lifespan. In extreme cases, they may need to be replaced.

Most Common BMW Problems

  • Oil Leaks: Oil may drip from gaskets or engine seals, which is very dangerous to the car.
  • Cooling System Failures: Components such as the water pump or the radiator itself can decide to pack up and leave the engine boiling.
  • Electrical Malfunctions: A problem with the car’s electrical parts caused by sensor or wire problems.  
  • Timing Chain Issues: Timing chains can stretch, produce noise, and impair engine performance.
  • Transmission Problems: Problems with gear changing or slipping sometimes require costly repairs.

BMW Maintenance Issues

  • Frequent Oil Changes: Changing the oil often will be crucial for properly running the engine and avoiding harm.
  • Brake Pad and Rotor Wear: The brake pads and rotors must be changed to ensure safety due to wear and tear over time.
  • Carbon Buildup in Engines: When burnt incompletely, carbon can accumulate in the engine, making it less efficient.
  • Transmission Fluid Service: Regular inspection and replacement of this fluid is necessary to prevent shifting problems.
  • Suspension Component Wear: The suspension parts on the car also degrade easily, resulting in a bumpy ride and poor handling.
