I have an R reg 300 TDI and the dipped lights only work when they want to. The side lights and the main beams work fine all the time. When the dipped lights fail, the dim-dipped does n't work and put the lights to 1/6 power, they just turn off leaving the side lights on. Does it sound like a problem with the dim-dipped control unit, or a loose power supply, and if so where should I start looking?
Many thanks in advance
