Graeme,
Thanks for the extra information - armed with this I shall see what my local dealer has to say, as I have to call by to talk to them this week anyway. If they have anything useful to contribute I'll pass it on. It does seem that at least your vehicle and mine are set up the same (dodgy) way in this matter, as what you've described mirrors what I saw. I wonder about other D4's?
Re the ride on rough surfaces - so far have only done a few k's on corrugated gravel, and things seemed pretty smooth to me. But I've never driven a D3, so have nothing to compare with in this area. Am heading out into the goldfields on a 2000 k work trip in two weeks, so will have plenty of rough & rocky stuff to trundle across - we shall see if the grin remains after that lot!

Reviews have said the D4 is stiffer than the D3 and not as smooth on dirt roads.
You could try adjustable rods and make them slightly longer (lower pressure in the air bags) may make a difference.
Have you spoken to the dealer about the lights?
-
At least 1 motoring journo at the Scottish release thought the suspension upgrade was a backward step except when driving at high speed, which got me thinking about the possibility of retrofitting D3 shocks & sway bars if the ride was bad enough. For the moment I'll add my extra weights and see how it goes with a few kms under its belt. My 80AH AGM now sits in front of the main battery and I await the release of a suitable bbar, to which I will mount my winch if it improves the ride.
Lower pressures in the bags would reduce the bump stop clearance so no joy there either, although it wont be the air springs causing the stiffer suspension if they're the same as the D3's.
I will in time contact the dealership formally to get a complaint to LR. However I don't envisage LR would be redesigning the lights and providing replacements so I wouldn't hold my breath for a fix, unless LR can fiddle the bi-xenon mount to line-up with the halogen. I'm not about to dismantle the assembly myself but if the bi-xenon unit is self-contained then its aim might not be fixed.

Just a quick update on my situation re high beam: went out last night to do some checking, and found that my set up is exactly as Graeme has described. Halogens on both sides are high and wide, but bi-xenons are pretty much spot-on. Driving through a cutting with high banks the halogens were doing their best work about 5 metres up the bank at a 45 degree angle in front of the vehicle!
Have contacted the local dealer, and they've asked me to bring the D4 in on Thursday. We shall see what they can do - tho given what's been said thus far in this thread I am doubtful of any positive changes. Will post the outcomes here on Thurs night.
-
As the front end has been chaned and the D4 has new lights. The halogens are part of the light cluster and if they are not pointing in the right direction there must be design fault. The whole unit will need to be adjusted to get the halogen pointing in the right direction. Maybe the fixings can be bent to suit?

CaverD3,
There's no difficulty in adjusting the lights based on the dipped beam of the bi-xenons, but with them correctly set (as delivered) the halogens are way too high. However from your 2nd link above it seems that at least 1 D3 has the same problem, with the dipped beam having to be set too low to get the halogens lower yet really still too high. If 1 D3 has the discrepancy, I'd expect all with bi-xenons to be the same. How's the alignment of your D3's lights?
My D2a's dual headlight unit does not suffer from this discrepancy, with good aim for both the low and high beams.
-
I would be asking if you can adjust the shutter in the Zenons on their own.
-
Its not just the shutter because when on high beam the bi-xenon is way below the halogen. However, from looking inside the back cover and into the front of the bi-xenon, the bi-xenon appears to be mounted in its own assembly and that assembly mounted on the adjustable section. If this is the setup then perhaps the bi-xenon assembly hasn't been fitted properly, or at least can be re-aligned using appropriate spacers. A task for LR, not me, lest I break something.

:BigThumb: Yup, their problem. :D
