Hi,
My 2002 V70 headlights were always giving me trouble, check the fuse, also on mine the connectors were broken so bad that I had to remove the plastic from around the steel connector, then I put electrical tape on each one to keep them from touching each other. I had both bulbs go bad at the same time also. Volvo's are a fussy beast keep the faith, I bought my first Volvo in 1975. Bondoman

 

Is this an '01 or later and you're getting the "DIPPED BULB FAILURE" message in the text display? This is pretty easy to fix, there's a shunt resistor in the CEM in the driver's footwell that gets hot and fails. This page shows you where it is and even gives you a part number to buy a replacement:

But DON'T drill the hole as is shown on this page, just pull the shunt and replace it with a new one.

You can try cleaning the leads on the old one with some 600 grit sandpaper, but the new part is cheap so I recommend not bothering with the cleaning.

You can also try cleaning out the slot on the CEM (also with some 600 grit paper, folded up) but it's pretty hard to get in there. If you look, you'll see the slot is probably discolored from all the heat.

I've had to do this several times on my '01, the last time the spring connector in the CEM wouldn't grip the replacement shunt properly, so I had to build up the thickness of the shunt lead with solder and file it down to a uniform thickness. Knock wood that's been working fine for a while.
