High Beam Assist....needs assistance?

[RoverLander]

I have a D4 HSE with High Beam Assist (HBA). I optioned up for HBA as I liked the idea of not blinding people as I fumbled for the high beam lever particularly as I sweep around a blind corner and an oncoming car suddenly appears.

However I find that there are many times that the HBA does not react fast enough and I end up looking at some poor oncoming driver’s squinty eyes as he tries to navigate his way around a mass of Bi-Xenon light. :cool: It is fine along a straight. However any reasonable turns causes the system to not react in time. It seems a little worse on left hand turns.

I have had the windscreen replaced due to a cracked screen but it was also doing this before the new windscreen. Does anyone else have this problem? Is there a HBA sensitivity adjustment that the dealer can fiddle with? Or is this normal with these systems?

From my experience on my HSE D4 with HBA, that seems about normal. It is more sensitive for lights approaching from the right side of the road. Works well most of the time. If it gets annoying around town, I'll switch to manual sometimes. Out of town, I still use the HBA most of the time. Not aware of any adjustments other than setting which side of the road we drive on.

Better having it than not having it in my opinion.

Aren't the Bi-Xenon only HID on low beam:confused:

Aren't the Bi-Xenon only HID on low beam:confused:
Bi = 2 = high and low. there is a shutter in the projector that moves to provide high beam. the 2nd globe in each side is QH but there is a high beam pattern produced by the HID projector as well in the Bi systems.

I turned off HBA about a week after I took delivery of my RRS - it just isn't a good feature in my opinion.

Jon79f,

I agree. It just doesn't work the way you would expect or want it to. It has caused more problems than simply not having it. This may be a bit of a warning for those considering HBA when buying a D4. Don't bother.
