 Hello all:

I have another headlamp issue. My lovely 2006 C6, which is slowly nickel and diming me into early bankruptcy, has another headlamp problem.

Aim.

When driving at night about 2 in 10 oncoming cars flash me. I noticed even before this that low beam does not show the road in front in the same "j" form as all of my other vehicles and using high (or main beam) illuminates the tops of the trees and is excellent for spotlighting possums etc.

Could it be the stance of the car that is causing this? A tired rear suspension perhaps?
I will add a picture below.

The gap between the top of the front tyre and the mudguard looks a bit bigger than the same on the rear tyre though...
The sill looks to be parallel to the road however.

Before I divert my local auto-electrician from installing bling (add-on crapola) onto cheap rubbish Chinese 4 wheel drives for 12 year old aspiring Nigel Mansells, how does the stance of my car appear to others?

Aside from what I said above, I think it looks quite normal

 The ride height looks too high to me, almost as though the suspension is in the intermediate-high position, rather than normal.

 Yep, looks a bit high to me also, particularly the front.

Check the suspension height sensor brackets are not bent out of shape or just bend them down a bit to adjust. It's quicker and easier than doing it correctly with Lexia

That's called an 'analogue' fix Mike, we still do them on older cars

 Thanks all.
Now after reading your comments, I see what you mean. I will take another look at the problem. The ride is still really good and comfortable, though hitting a deep pothole on the front right still causes a distressingly loud bang.

The bang I suspect is an old car problem.

I will have the front ride height looked at by my Citroen bloke when next I am in Sydney.
