I have a 2002 V40 with no power to the left headlight. I checked the fuse and there is power on both sides of the fuse. From what I have been reading, it appears that I should be checking for power at the CEM unit. Where the CEM unit located? Does the CEM unit have a history of giving trouble?

Thanks in advance for any help in this matter.

The CEM is located underneath the dash on the drivers side. There is a panel with 4 screws, and then the CEM is held in with an additional 2 screws. It takes about 5 minutes to get to this part, so don't let a dealer tell you otherwise. Also, the CEM should NOT require programming, so don't let them hit you with that charge either. The part alone is $700, so look on eBay first.
