What causes the BMW E66 remote control to be unresponsive?
1 Answers
BMW E66 remote control unresponsiveness may be due to a fault in the anti-theft system. Distinguishing the older E66 models: Check the headlights: if they have a light brow and the brow is yellow, it is definitely an older model. Alternatively, check the vehicle's production date; September 2004 is a dividing line. You can also see if the headlights have active steering or check the taillights. Remote key: The system mainly consists of a transmitter and a receiver. It is powered by a battery, emitting a small wave from the key. The car's antenna then receives the wave signal from the key, which is identified by the electronic control unit (ECU) through a specific signal code. The system's actuator (motor or electromagnetic coil) then performs the lock/unlock action.
