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.
No idea about Alfas :(

On Omegas, its normally the sensor on suspension arms has come unclipped, or the servo motors seized.

That's interesting.....where are the servo motors?

On the headlamps

FFS. I suppose he won't shut up until someone makes a useful suggestion.

Have you tried this?

 :o :o :o

Navtec? WTF has that got to do with anything????

Already got this from the nice, friendly alfa forum:

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



There is another way to do this. Either blow up the front tyres and let down the back ones (or vise versa) to correct the miss-alignment, or solder 4K7 resistors onto the track ends of the measuring potentiometers. That's bound to fix it.  :y :y :y

Cheers Ken.

That's OK, your welcome.

Don't clap just throw pound notes !

And what exactly do they adjust (complete lamp, reflector etc) and if they are seized how do you unseize them?
