check the cam shaft position sensor
check fuel pressure at the rail
run the fault codes again

Go to Saab forums at Saabscene where you will find an article on camshaft sensor positions.

There is a headlight relay under the fusebox lid inside the engine compartment.

Some vehicles use a circuit breaker in the headlight circuit so that when there is a short then the breaker opens and then closes so that night vision is not totally lost from a blown fuse . Check out the system for a blown fuse or faulty breaker or faulty light module.

Sounds like the main headlamp relay. Located in the fuse panel. You may be able to swap it over with an identical one that powers another system to test it. Note - make a note of the position of any relays you remove, It can be confusing when there are lots of empty slots.

Bad news for you, it's located in the gas tank on the fuel pump.

If Halogen light bulb:
Ok then this is either an issue with the headlight switch or harness to the headlights . We're these checked ?

Hi Yamin, Sorry guy, replace the battery! Regards John

I read over the recalls and they do have recalls on brake and turn signal lights but not the low beam headlights while driving at night.

Sounds like the relay or headlamp driver module relay 46, for the headlights is going bad, though.
Or, it could alternatively be bad grounding of wire somewhere or bad wiring in general.

I would check in the underhood fuse box for the relay and see if wiggling it to ensure a good connection helps matters.
