BMW 5 Series shows permanent throttle failure.

It may be that the variable valve timing click is damaged, or there may be something wrong with the engine computer and the line plug.

Due to the design defects of the variable regulator of the old Vanos, the throttle motor was replaced due to damage or spring fracture, and it can be driven by computer, indicating that the motor is fine. The next thing to check is that the variable regulator screw may be broken, or the fixing bracket may be worn, and the broken spring and the faulty lamp caused by insufficient power.
