Engine Issues
One of the most significant concerns for BMW 320d E90 owners is engine-related problems. While the diesel engine is generally reliable, certain issues can arise:
- Turbocharger Failure: The turbocharger can fail due to oil starvation or excessive wear, leading to a loss of power and increased fuel consumption.
- Fuel Injector Problems: Faulty fuel injectors can cause rough idling, poor acceleration, and increased emissions.
- Oil Leaks: Common areas for oil leaks include the valve cover gasket and oil filter housing, which can lead to significant engine damage if not addressed promptly.
Transmission Troubles
The transmission in the BMW 320d E90 is generally robust, but some owners report issues that can affect performance:
- Transmission Fluid Leaks: Leaking transmission fluid can lead to shifting problems and ultimately result in transmission failure.
- Delayed Shifting: Some drivers experience delays when shifting gears, which can be attributed to low fluid levels or worn components.
Electrical System Glitches
The electrical system in the 320d E90 can also present challenges. Common electrical problems include:
- Battery Drain: Some owners report issues with battery drain, often due to faulty alternators or parasitic draws from electrical components.
- Faulty Sensors: Various sensors, including the ABS and traction control sensors, can fail, leading to warning lights on the dashboard and potential performance issues.
Suspension and Steering Problems
The suspension and steering systems are critical for maintaining the vehicle’s handling characteristics. Common issues include:
- Worn Bushings: Over time, suspension bushings can wear out, leading to a rough ride and poor handling.
