Overheating or Coolant System Issues

The BMW 4 Series is designed to be a high performance vehicle. When the engine is running hard, it creates a tremendous amount of heat. For this reason, the car’s coolant system must work properly to prevent overheating and severe engine damage. However, some components can fail and must be replaced or repaired quickly.

Typically when we see an overheating 4 Series, it’s because the coolant system is leaking or the water pump has failed. The plastic components can quickly wear in the 4 Series water pump and coolant lines, which is the main result of these issues. If you’re noticing the car running hot, come see us immediately to avoid major damage. Our team is well versed in coolant system diagnosis and repair.

Excessive Oil Loss

Like the coolant system of the 4 Series, plastic components which seal oil in the vehicle also can quickly wear and cause leaks. Many 4 Series owners report oil loss and having to top off between services, which is not ideal for the owner or the car itself.

While it might seem fine to be forced to put more oil into the car from time to time, consider where the missing oil is going. In many cases, it’s leaking onto other engine components. When this happens, further issues can occur. If you’re noticing a low oil level, our team can perform a complete diagnosis and make a full repair to stop oil loss.

Electrical/Sensor Problems

Part of the reason for the 4 Series excellent performance and luxury feel is the integration of high tech components into the vehicle. The car’s computer helps the engine run at peak efficiency and allows for unparalleled driver comforts. However, this tech also creates points of complication.

When a sensor goes bad in the 4 Series, it can significantly impact performance. Some sensors are even programmed to put the car in “limp mode” if they’re tripped. If you notice error codes or if electrical components aren’t working correctly, you need an experienced team on your side. We can read the car’s error codes and get to the bottom of the issue.

Carbon Buildup

LIke many other modern and high performance vehicles, the BMW 4 Series uses a system of fuel intake called direct injection. In this type of engine, fuel flows directly into the combustion chamber, resulting in better fuel economy and performance. However, this system does have a drawback: carbon buildup.

Because fuel does not flow over the intake valves, over time carbon accumulates in this area. When it does, the car won’t get the fuel it needs to run properly. Symptoms can include engine misfires, poor fuel economy, and stalls. Our team has dealt with this issue often and we have the right equipment to remove buildup properly.
