Dipped beam fault
Hi there,this is my first time on this site and hope that someone will be able to give me some advice.I have a 2001 406,2.0 hdi 110 bhp and a few days ago the dipped beam on the drivers side stopped working but side and full works fine.I did the usual-change bulb,check fuses and nothing.Could there be a separate panel of fuses in the car,as far as i know the headlights have separate fuses and I only checked the panel that's under the steering.

There is a second fusebox in the engine bay, just next to the battery box and the airbox.
If you have access to a multimeter, you can measure the voltage being applied to the terminals that connect to the bulb itself, see if there is power getting there.

Re: Dipped beam fault
Graeme's right, there are 4 10A fuses, (one for each dip & main beam). On later D9's these are F9, 10, 11, 12, they may be different on earlier cars. As your car is a 2001 it could be either layout.
I've had the same problem myself - the bulb filament blew in the normal way, but then the wires that connect to the ends of the filament decided to weld themselves together.

Thanks for the fast reply,as soon as I get home I'll have a look on the other fuse box.The wires are okay...at least what I was able to see,I'll keep you posted on what I find out

Re: Dipped beam fault
I meant the wires inside the faulty bulb, (didn't explain too well).

Re: Dipped beam fault
Okay,got home yesterday,checked all the fuses in car and under the bonnet,again, 3 times(don't know exactly wich one is for the headlights) they all looked okay.When I get home today I'll go buy a multimeter and take the headlight off and see if I can find the fault.
