So I park up tonight, and unusually, I park with the front towards the garage door, when I notice the headlight beam pattern on the near side is about 3/4 inch lower than on the offside....

So out comes the tape measure, and yes, the near side is lower. Nothing else seems wrong, air suspension works fine (the discrepancy between left and right is the same on any setting), no error messages, and it passed its mot ok in November.

I will have a look tomorrow in daylight, but any ideas? Broken spring? Presume the airbag should be fine since the air seems to be going up and down ok.....

Btw, it's a 2003 with 150,000 miles....

You'll need to give the height sensors a visual first. Might be something obvious there. Previously..

So what is the height difference at the wheel arch compared to the other side. Allow a tolerance of any where between 4 & 10mm. That said, if it is obvious to the eye, then it will offend and need sorting  .
Experience is the only genuine knowledge, but as time passes, I have forgotten more than I can remember

If your drive is not flat then that will do it! Park it on a known flat area and measure again to be sure before you panic about it...

Thanks everyone! The height I measured was from the ground to the flat part on the top of the bumper, so any slope to the drive should not effect this. What/where are the height sensors? I'll go measure the height of the wheel arches today.....
