I have an el xr8 and the the drivers door seems to be playing up with the smart lock.Sometimes when i use my remote to open the doors all but the drivers opens. Ocasionally all the door locks go up and down whilst im driving(as if im pressing the buttons) any ideas??? should i just replace the smart lock module???

ummm, i think you'll find one of our actuators is f**k, if you have a look in the technical documents i think you should find your solution
