Headlight levellers

Going to have a look at my levellers tomorrow. I'm on a roll now after doing the maf. Trouble is, I dont really know what I'm looking for. The garage said it looked like someone had had a jack under them. I am hoping I may be able to just undo the damage done with a bit of grunting and bending. Before I take the plunge, ANY advice would be great. Thanks, Steve.

Re: Headlight levellers

Are your headlamps pointing down too much due to damage to the axle sensors that measure vehicle pitch? If so then all you really need to do is bend the brackets that hold the sensors back to somewhere close to their normal position, and then reaim your headlamps.
All the sensors do is send a signal to an ECU that calculates whether the car is pitching, which then adjusts the headlamps to stop them dazzling oncoming drivers. If these brackets have been bent out of shape then the signals from the sensors (basic potentiometers) will have changed, and hence the ECU will think that your car is permanently nose up/down, and hence set the headlamps to an incorrect position.
You could however just reaim your headlamps to a correct aim and not bother sorting the brackets but this may lead to problems with the levelling system being permanently biased to one side of it's operating range and the posibility of it operating outside its adjustment range. This can lead to the reflectors in the headlamp being wound off the end of their adjuster screws which would then require new headlamps.
Hope I have picked up on the right meaning of your post and this hasn't just been a complete load of nonsense and good luck

Re: Headlight levellers

That is exactly what I wanted to hear. My headlamps are, indeed, too low. Thanks for your help, it is much appreciated.

Re: Headlight levellers

I assume you have xenons, and therefore you may only have problems with the connection of the leveller to the headlight.

Do a search back in the forum

To check, take off the headlight leveller (rotate & gently pull). If it comes off easily, it wasn't put in properly, if there is resistance, it was & there is another problem - prob'ly the sensors on the suspension.

You will need to wiggle the leveller back into the light whilst giving pressure backwards (using the main beam bulb holder area) - tricky the first time.
