Hi am new to forum read a few old posts on this but they give conflicting info. I have 07 9-5 1.9 Diesel TID my headlihts come on drop to the lowest level and stay their then the warning light comes on . Was wondering if someone more knowledgable than me might know what the most likely culprit is . Have read that it's most likely to be the front sensor or wire to that sensor . Just wondering if anyone had any thought's have read that it could be a relay or a bulb any thoughts would be much appreciated .
