Hello, our Volvo S 80, built 06-2002, has normal dipped light, that is H7 55 W. The night before yesterday, when driving off, suddenly the yellow warning light went on and I have since on the display the display “Abblend light defective”. In fact, the dipped light remains on the right side. I have checked the following: All other lamps work, so also the main light and the fog lamps on the right. The two light bulbs of the dipped light left and right and the fuses are in Ordnu ng. I measured the following values in the fuse box in the engine compartment: fuse 18 (headlight left) 11.58 V, fuse 17 (headlight right) 0.04 V. I also measured directly on the headlight, where identical values arrive. Lights out: Both values jump to 0.00 V. Who can give me a tip. If I drive to the “friendly” one, the troubleshooting there already exceeds my budget. Are there perhaps upstream relays that can be exchanged on an experimental basis? Fa lls yes, where are these relays located? Thank you already now, many greetings and good drive your Walter Tagora
