LR D4 Problems

They're called bi-xenons because they work both as low and high beam. Low beam uses a shield that provides the usual low-beam cut-off but on high beam the shield moves out of the way. Watch the cut-off in the middle on low beam then switch to high beam.

Does your halogen high beam shine (fill in) on the same plane as the bi-xenons or is the halogen beam significantly higher than the bi-xenons? It seems that some halogens shine on the same plane yet others are used to spot possums high in the trees.

The xenons on high beam should create a clean white and narrow spot beam down the middle of the road, which is quite easy to pick although the low beam pattern of the xenon also stays in place when high beam comes on. Easiest way to test it would be to hang a couple of towels or similar in front of the halogen lenses to block them off and then watch what the xenons produce on their own without the halogen effect. From the description you've given it sounds like you might have a problem with both xenons, which suggests perhaps a common switch or fuse controlling the xenon high beam.

Hi Graeme, Yeah I'd read about the shutters on the light but I just couldn't tell if they were doing what they should be doing...they are pretty bright to look at. However, I've managed to position the car shining the lights against my garage door and they appear to be fine...there is a change in the xenon. I don't know what the idiot at LR was going on about then...maybe he thought I meant two seperate xenon lights? :confused:

You're right on the Halogen front though. They are definately illuminating way too much foliage. I'll look at your other thread you have on adjustment but I'm assuming it's LRs problem?!

D4 is in today getting it's suspension compressor replaced.

I hope that's the end of its 'moodyness'

:)

D4 Suspension Compressor replaced....so far so good.

The most obvious difference is the fact that the nose comes up straight away. The D4 used to come up bum first which was always a sign that it was going to be tempermental!

Now, if LR could just get that puddle lamp I've been waiting over a month for, I'd be happy....:)

That's what mine does all the time. I thought it was normal.

Couldn't tell you Graeme, and could never get a straight answer out of LR as to what was normal and how long it should take to get from standard to offroad.....my best was probably 2 - 3 seconds. I suspect normal is around 5 secs...depending on temp and usage I suppose (as in how full is the accumulator).

If mine came up butt first (really obviously butt first), I knew the front was going to struggle....which in the end culminated in hanging between selections for up to 5 minutes, a couple of complete failures and multiple overheat warnings (even when stone cold).

If yours is working fine, normal operation probably isn't restricted to any particular sequence. Mine probably still is coming up butt first but now the front lifts quickly after it (less than a second). Before, the ass came up and then the front really struggled.....on a bad day.

Cheers.

I was told that rear should come up first so as to not shine lights up at any on coming cars made sense to me .

However if I go up and down more than once it takes over 3 mins to go up second time (which makes it useless on the sand asit goes down at 50 km/h)
Dealer tried recalibration, new compressor, LRA tech were called and I was told that was with in spec for car, got letter from them to cover me latter, because obviously not right. Have been waiting for others to notice the fault so that some other dealer may put in the effort to fix it.
Cheers Ken

Yup, the sequence makes sense.

That's troubling on the timframe however....that is useless when going through varying terrain.

Is this on a D4?

Yes D4 3lt HSE, had D3 before wasn't like this, it would go up & down half a dozen times before slowing, but LRA say its within spec because some others do it as well. when the chq clears the service dries up :o:wasntme:
Cheers Ken
