Common BMW Faults

Attention all BMW enthusiasts! Are you the proud owner of a BMW or considering purchasing one? While these luxury vehicles are known for their high-quality components and unmatched driving experience, many owners have reported common problems that can put a damper on your driving experience. 

But fear not, as an independent family-owned garage with over 40 years of experience, Fitch Autos has got you covered! In this blog post, we’ll be discussing some of the most common issues that BMW owners face, and provide you with valuable tips on how to maintain and repair your vehicle. So buckle up, and let’s dive into the world of BMW ownership.

Common BMW Faults

What Are the Most Common BMW Faults?

There are several faults that you may experience when owning a BMW. However, let’s take a look at the most common BMW ones….

Engine Faults

Every machine, including BMW engines, wears out over time. Although you can generally prevent these problems with regular maintenance, sometimes the age of the vehicle, accident, or general wear and tear could be the cause.

The following are seven BMW engine problems you may encounter:

  1. Cooling System Damage – Water and coolant circulate throughout the cooling system of your BMW to prevent it from overheating. It is not uncommon for BMW cooling systems to fail occasionally. Rather than faulty design, these issues are related to wear and tear on specific components. These problems can be prevented through regular servicing and maintenance of your BMW.
  2. Water Pump Failures – The failure of the water pump is a common complaint among BMW owners. There have been recalls in the past for some BMW models due to overheating caused by water pumps, including the 2012 BMW 650i, 2012 BMW 550i, and 2012 Mini Cooper S. The BMW water pump is significantly different from a traditional mechanical belt-driven water pump. BMW pumps are electric and made of plastic. In the event of a water pump failure, the engine may overheat and fail
  3. Thermostat Failure – There are two settings for the thermostat in a vehicle: closed or open. The vehicle can quickly reach its ideal operating temperature when the thermostat is closed. Upon reaching the average temperature, the thermostat opens, and the cooling system begins. Occasionally, BMWs have faulty thermostats that fail in the closed position, resulting in a malfunctioning cooling system, which also results in overheating. It is possible for the radiator to crack when the engine heats up rapidly, causing severe engine damage.
  4. Defective Timing Chain – There have been several instances of BMWs with prematurely failing timing chains. Over time, your BMW engine’s chain will stretch and become loose due to wear and tear. The timing chain and other parts of the timing system can last longer with regular servicing and maintenance. A timing chain issue with your BMW may cause rough idling, strange sounds, or a check engine light to illuminate.
  5. Malfunctioning Fuel Pump – Several BMW owners have reported problems with the high-pressure fuel pump in their vehicles. Symptoms of a failing fuel pump include poor acceleration and stuttering.
  6. Defected Camshaft Cover Gasket – BMWs are prone to oil leaks. You may notice brown spots caused by an oil leak under your vehicle. There is a common problem with BMW camshaft cover gaskets leaking oil. By sealing the joint between the engine’s valve and cylinder head, the camshaft cover gasket (also known as the rocker cover gasket) prevents oil leaks. Most leaks are caused by gasket wear and tear. 
  7. Oil Camshaft Gasket Leak – Oil leaks from the oil camshaft gasket tend to occur with BMWs. Over time, dirt and debris can clog the gasket, halting its performance. If the oil camshaft gasket fails, the engine can suffer severe damage or even fail completely. At Fitch Autos, we recommend routinely checking and changing the oil to prevent leaks.

Door Locking Faults

In general, BMW vehicles have reliable locking and unlocking mechanisms. However, occasionally, owners have reported problems unlocking or locking their BMWs. BMW X5s are known to suffer from this problem. The best solution is usually to replace the door’s lock mechanism. However, door locks are a complex mix of mechanical and electrical components so we would always recommend that you seek assistance from Fitch Autos for a first-time fix solution.

Electrical Faults

There are several common electrical faults that BMWs can experience. Here are some of the most common ones we’ve seen at Fitch Autos::

  • Battery Issues: BMWs are known to be sensitive to battery problems. If your BMW is not starting or experiencing electrical problems, a weak or dead battery could be the culprit.
  • Faulty Alternator: The alternator is responsible for charging the battery and powering the electrical system in your BMW. A faulty alternator can cause the battery to drain and leave you stranded.
  • Ignition Switch Failure: The ignition switch is responsible for starting the car, and if it fails, you will not be able to start your BMW. Symptoms of ignition switch failure include difficulty starting the car or the car not starting at all.
  • Blower Motor Resistor Failure: The blower motor resistor controls the fan speed in the Climate Control system. If it fails, the fan may not work at all or work only on one speed.
  • Window Regulator Failure: BMWs are notorious for window regulator failure. Symptoms of a failed window regulator include windows that won’t go up or down or that are stuck in one position.

It’s important to keep up with regular maintenance and address any electrical issues promptly to avoid further damage and costly repairs. Fitch Autos have expert BMW technicians that can help.

BMW Faults: How Do You Identify Them?

There are several signs that you may notice if there is an engine or electrical fault with your BMW. Here are some common ones to look out for:

  • Warning lights: If any warning lights appear on your dashboard, it may indicate an issue with your engine or electrical system. Common warning lights include the check engine light, battery warning light, and oil pressure warning light.
  • Strange noises: If you hear any unusual noises coming from your engine, such as knocking or tapping, it could be a sign of a serious problem. Electrical issues may also cause unusual noises, such as buzzing or clicking sounds.
  • Poor performance: If your BMW is experiencing a loss of power, sluggish acceleration, or a decrease in fuel efficiency, it could be a sign of an engine issue. Electrical problems can also cause poor performance, such as issues with the ignition or fuel injection system.
  • Smells: If you notice any strange smells coming from your BMW, such as burning rubber or oil, it could be a sign of an engine issue. Electrical problems may also cause a burning smell, especially if there is a short circuit.
  • Difficulty starting: If your BMW is having trouble starting or won’t start at all, it could be a sign of an engine or electrical problem.

If you notice any of these signs, it’s important to have your BMW checked by our expert technician as soon as possible to diagnose and address any issues before they become more serious.
