my volvo always send a messasage saying position light failure . How can I fix that

I have this problem sometimes too. I usually find that one of the bulbs is not working but may not be burned out. If I jiggle it or pull it out and put it back, it re-connects and works fine. Sometimes it doesn't and I replace it. Most of these bulbs are easy to do yourself.

"Position" lights are the parking lights, one on each corner of the car. Just turn on the parking lights and walk around the car, you will see the one not working.

Your owner's manual will tell you how to replace it. Or, pay extra for the bulb and a dealer will not charge you to replace it.

I like to replace both front or rear lights at the same time. The autoparts stores sell the bulbs in packages of 2.

Klaus, you're my hero, you and others on this site have really helped me out since I bought my 04 S60 (NA) and realized I'd go broke if I had to take it to the dealer for normal maintenance and repairs. I really like the Volvo, but they do have some "Swedish/Euro quirks" which are fun to figure out. Like the "Position Lamp Failure". I eventually found that the "Position Light" isn't what someone in North America would call the parking lights, nor the brake lights; but a separate, stand-alone light which is supposed to be used as a sort-of reverse fog light. I think the idea is you're supposed to turn it on when its foggy so people behind you can see you better (or maybe you turn it on so people can see that you've pulled to the side of the road). Whatever the original intent, it's a separate lamp, above the brake light lamps, in the red lamp housing, and on my '04 it's on the left-hand side. There's even a button on the console with a universally easy-to-grasp symbol which clearly shows what this thing is for, and does. Needless to say, 4 years after we bought it my wife and I finally figured out what the postion lamp message was for, and that the bulb needed to be replaced. I definitely agree that when replacing brake lights, headlights, or parking lights, you'd better replace them in pairs. But there's only one Position bulb, and it's only on one side. Have someone step on the brakes, make sure both brake light bulbs on either side are OK, then open the trunk, look near the brake-light assembly, and find the extra position lamp bulb. With the key on, press the position-lamp button, see if it comes on; if not, replace.
Hope this helps.

Sorry to burst your bubble, but the position light is a corner light (parking light in the USA), not the rear fog light.

Europeans have different lighting systems. They require cars to turn on the street side lights when parked at night (position lights) and this is accomplished by either a switch on the dash or the turn signal with the car turned off.

Europeans also have motorized headlamp adjustment motors, allowing the driver to adjust the headlights while in the driver's seat. One will get a ticket for having headlights out of adjustment. The typical American is not trained on how to adjust lights and would have headlights all over the place!

Americans also are completely unaware when it comes to rear fog lamps. It is as bright as a brake light and really messes up following drivers when there is no fog at night. I remember gaining on a Jaguar for 15 minutes in Western PA at about 3 am. I first thought he was driving with his left foot on the brake until I realized he had 2 fog lights. It was hard on my eyes to have that much light shining on me.

If the dash light is on, indicating the fog light is being used, TURN IT OFF! unless you are in pea soup fog.

one bulb is out on your rear lights. Have a friend stand behind your car as you hit the brakes. Sometimes its hard to distiguish which bulbis out.
