E46 Central lock system

[jurai72]

Hi Bimmer sifu,I got BMW E46 320i year 2001/2006. I got a problem with my central locking system.It is not function if my car is under hot sun, meaning the temperature in the car is hot.when this happen, I have to open the door mirror and start the engine and switch on the air-con for 10 - 15 minutes and once the temperature is lower down, the central locking is working again.Same thing if I use the key to open the door directly without using the remote key.is anybody got same experience? what normally we have to repair or change?Thank you in advance...
