BMW Transmission Malfunction: Car Won’t Start
If your BMW won’t start and you see a transmission malfunction message, it can be a frustrating and worrying experience. This issue can be caused by a variety of factors, but it’s important to have it diagnosed and repaired as soon as possible to avoid further damage.
Causes of BMW Transmission Malfunction
- Low transmission fluid: This is one of the most common causes of transmission problems. If the fluid level is low, the transmission won’t be able to function properly and may overheat.
- Dirty transmission fluid: Over time, transmission fluid can become dirty and contaminated with metal shavings and other debris. This can cause the transmission to slip or shudder.
- Faulty transmission sensors: These sensors monitor the transmission’s operation and send data to the car’s computer. If a sensor fails, the computer may not be able to control the transmission properly.
- Mechanical problems: In some cases, transmission malfunctions can be caused by mechanical problems, such as worn gears or a damaged torque converter.
