First post of any forum, just bought a 04 645ci. Car is going great, just finding a few niggling things with it the longer I have it. The boot lid for one,if I lock the car with the key fob,open the car with the key fob,press and hold the boot release the boot pops up about 2 inches. I close the boot down,press and hold the boot button again and pops open fully perfectly. Seems once I lock the car and reopen it it fails to open fully again. Is there a function I'm missing....or is it just jammed?
