Malfunction of BMW 530li transmission system

This situation belongs to a wide range of diagnostic information and may involve many problems.

1. Clutch or transmission problems: Clutch wear, oil leakage, solenoid valve failure, internal gear wear of transmission or ECU failure may all lead to transmission system failure. Solutions may include replacing clutch assembly, repairing or replacing transmission, replacing faulty solenoid valve or testing and repairing ECU.

2. Sensor failure: There are problems with various sensors in the transmission system, such as speed sensor, temperature sensor and pressure sensor, which may lead to misjudgment of the system and report the failure. At this time, professional technicians are needed to detect and replace the faulty sensor.

3. Failure of transmission shaft, universal joint or drive shaft: If mechanical parts such as transmission shaft and universal joint are damaged or loosened, power transmission may be interrupted or unstable, and fault codes may appear. Damaged parts need to be inspected and replaced.

4. Software problem: The software failure or improper update of the on-board computer system may also trigger the transmission system failure alarm. In this case, you need to go to a 4S shop or a professional repair shop for computer diagnosis, and refresh or repair the software if necessary.

5. Lubrication system problems: For example, insufficient or deteriorated transmission oil may affect the normal operation of the transmission system, so it is necessary to check and replace the transmission oil.

6. Other component failures: such as turbine pressure reducing valve, ignition coil, spark plug and other factors that affect the output power of the engine, indirectly lead to the fault prompt of the transmission system.
