Car is at a mates, so haven't had a chance to go look -- but I am told both headlights are pointing skyward and won't adjust down.

If t'was the arms I imagine both wouldn't come off or snap at the same time, and lights would drop down, not up.

Is there one sensor for the pair or is each light levelled seperately ?

Thinking common issue with both lights: sensor (if only one) or wiring.

What should I go for first ? (remember I am a total numpty with cars !! )

on a Nissan?

I would say, regardless of make/model, that you need to check the sensor arms... I think they're generally on the N/S suspension (front and rear) but may be wrong. Sounds like one has popped off

Both lights pointing up indicates the system "thinks" the nose is low, so it would point to a sensor problem... depends on how many sensors and where they are ..

Sorry -- me being an idiot -- this is on the Omega -- facelift 2.5 elite (GNU)

usually if the socket falls out of the back of the sensor on the suspension arm, "headlight field of vision" is shown on the display and the lights default to their lowest setting. If lights are high, sounds like the sensor itself is intact but not connected to the suspension arm. Possibly one of the small rose joints has broken either end of the small, once chrome but now probably rusty, connector rod.

Basically, check both suspension arm sensors are in tact and connected from chassis to suspension. Both sensors can be seen between door and wheel front and back on the suspension arms. May help to turn the front wheels to right full lock. Remove for access.

I had this recently too. Suspension sensors appeared fine and were still connected to suspension arms.

Cleaned them up, removed connectors, a squirt of contact cleaner in each and reassembled with a bit of grease to keep them watertight and it is now OK.

Rear sensor voltage has now changed quite radically according to tech 2 so must have been a bad connection.

... Just to add, there is a calibration function accessible by Tech 2. I think this just zeroes the indications from the sensors on the assumption that the car is level and is probably used when a sensor is changed. Might be worth a try just in case the ECU has got itself in a muddle. Check the sensors and clean the connectors first though.

Cheers for the replies -- my feeling is sensors. one or t'other telling the lights the car is out of kilter.

Will try a clean up first, Kevin, assuming all look ok otherwise ( cheapest fix first!).

Thanks again all
