What owners wrote
Tl*the contact owns a 2004 BMW 325I. The contact stated that the faulty lamp warning indicator would intermittently illuminate on the instrument panel. The electrical harness that plugs into the rear of the lamp harness for the exterior lighting had a faulty ground in the connector. The dealer stated that the wires could not take the heat distribution, which caused the wires to fry inside the connector. The failure also caused the turn signals and rear lamps to not operate correctly.
The vehicle came equipped from the factory with bi-xenon auto leveling headlights manufactured by zkw. The light output of the headlights is below any vehicle that I have encountered on the road. Cars that are over 20 years old have brighter headlights. I have replaced the bulbs and it hasn't helped. Looking at it further, brown scorch marks are visible in the projector when the headlight is on. The rear of the projector is completely brown and burnt. At night, it is becoming very difficult to see.
