I have an 06 V70 2.5L t with an odd electrical problem, just wondering if anybody has experienced the same. My R/H low beam headlite is energised with the starting of the car but after three seconds goes out, every time. At first thought it was the bulb but then it started working again. After a few weeks the gremlin has returned, seems like a relay times out. In the wire diagram There's a shaded box in the headlite fixture listed as "Bifunc BDL", can't find what that abreviation is for.......anyone?
