Most likely just replace it. You could pull the fuse and then use a small screwdriver to try and pull the tabs inside the receiver in toward the center a little. It could be that repeated insertion and extraction of the lighter or accessory plug has bent them outward enough that they're not making sufficient contact to power what you plug in. If that doesn't work, replace it and then put the fuse back in.

if the fuse is good and there is no relay then either you have a loose ground/positve wire or the socket is bad. you can easily purchase a after market socket from Napa or Oreillys for a few dollars of the problem is not a loose wire or bad fuse. good luck please rate this solution...thanks

SOURCE: cigarette lighter fuse location

The cigarette fuse is located in the battery junction box under the hood, it is fuse # 10 and is a 20A fuse, open the hood and find the box it is on the passenger side towards the back of the compartment, it is 10th in line on the top row, also you can check these fuses without removing them through the clear plastic top so that should make things a little easier too, hope this helps

I had the same problem with the suspension on an o2 X5 Sport,it was the stabiliser pump in the rear,Range rover is the same pump and is cheaper than the BMW part,they also do an exchange unit.
