Question about 2003 Porsche Cayenne
Warning light indicating "brake proportioning" on . Also still running even after key is out of ignition.
Not sure if you've solved your problem but I do have the answer. Also you failed to state that your vehicle will not go into drive because of this warning, which is generally the situation. When the drain ports under the hood clog, moisture runs down under the rug on the interior causing the wiring harness connectors on both sides of your vehicle to corrode. You need to remove the kick plates that cover the rug. Pry the rug away to expose a plastic shroud that covers the harness, just in front of each front seat on the floor. At this time you'll probably notice how wet the rug and it's foam backing is. Dry this out with towels and a hair dryer. Remove the harness cover. You'll see a clear plastic cover and a harness which looks like it's covered in electrical tape. Unwind the tape. This will expose the harness and connectors. If I can remember correctly, there is three connectors on each side, driver's and passenger's. See how corroded they are. Some maybe broken off. Cut back and clean these wires. Before connecting them, use a fine sand paper to clean the wires. Make sure these connectors are facing up and now cover them better than Porsche did. I used electrical tape and plastic wrap, followed by black plastic pull ties. The drain hoses, terminate under the vehicle, just in front of both doors. You'll also need to remove the plastic covers under the hood on both sides of the engine compartment beside the wipers. This will expose the firewall where the drains are generally full of debris like small sticks and rotting leaves. You'll save at least $2000 doing this yourself. Not knowing how to do this, it took me approx. 3 hrs. to do the job correctly. Good luck.

Sounds like it can be just a bad bulb but it doesn't have to be. If the car has ever been wreaked then it's possible that the wiring has been pinched somewhere near the headlight. The dimmer switch is in the steering collum and it would be effected buy turning but it's more likly to be efferted buy both lights not one There's a fuse panel near the drivers left kick panel that has the headlight fuses in it and it's possible the fuse is'nt making a good connection. With the lights on and the czr not moving you may just have to pull on the wires move the fuses and turn the steering wheell to find where the problem is. The dimmer switch should effect both lights.

If all these lights are on, one common issue for these cars is the ignition switch. Not hard to do. Wiggle the key and see if the lights will flicker or go off. Let me know.
