That was nearly expensive

On my way back from a camping holiday in Suffolk i had a warning light start flashing (ASF Check) and at first was going to stop then realised it was the headlight aim system so carried on as did not need the lights.

Had a look an here when I got back and found a few mentions of the height sensor on the rear offside suspension so had a look and found the bracket had snapped where the adjusting rod connects to the supension (furthest from the sensor).

Saw some of the prices they were mentioning on here for a replacement so popped it over to my friendly local near work and asked them to have a look.

One repaired (welded) bracket and £20 cash and no warning light anymore.

One thing I am curious about ... this ASF system ... I switched it on when setting things up on the car .... what exactly does it do .. is it height only or direction aim too?

How does it work and ... does it actually work and make a difference?

It swivels the lights right/left as you turn the steering wheel.

These things are usually quite subtle and hard to spot around town etc. Had it on my XC90 and assumed it was a bit of a gimmick until I had to do a late night hospital dash in the Scottish Borders with my eldest. Very noticeable on unlit country roads. And obviously the little dance the lights do when they first come on. On my 400h it's best tested in a dark garage.

So if this sensor on the rear offside suspension is for the height is there another one on the steering system, , if so does anyone know where abouts it is?

Wouldn't it be the steering angle sensor just below the steering wheel, in the steering column (well it is on the Mercs)?
