Random musings on the D4

Recommended Posts

Good thread. I had several brand new D4's on loan in the past and was tempted to get one at the time. There is no way I would entertain a D5, blandness personified.

Brief update on the windscreen/special brew farce... 

Even after excessive cleaning effort, the greasiness just returned, so I thought that it must be impregnated in the wipers themselves. I got a couple of nice Bosch ones from my local shop and cleaned the screen again before fitting them -  now all is loverly!

Notes:

  • if it wasn't for the internet, I never would have worked out how to unclip the original ones. 
  • Also on the internet "you should replace wipe blades every six months"  😮 I usually replace mine when they tear... I would be interested to hear other's views on this.

I replace them if they start squeaking or don't wipe cleanly, doesn't cost much and makes driving that little bit nicer.

Yup, once they harden a bit in winter and start skipping they get replaced.

In summer with warmer weather obviously this is not an issue :)

Ha! I’ve used “The Knack” video more times than I care to remember when running various training workshops. It’s a great icebreaker or indeed just a good laugh if things get a bit dry.

I’m not a Discovery driver but I’m enjoying the thread.

Snap. Smeary or juddery wipers are too irritating to tolerate. The best thing in the world for cleaning a slightly smeary windscreen is something called Mixra, used to be Holts now Simoniz. Miracle in a can. None of the other glass cleaners come close.

Agreed, mixra is excellent.

Thanks to those who recommended mixra - I have never heard of it... On order now :)

OK so here is a problem that is WAY beyond me... I want to be able to open/close the windows when the ignition is off. Several times recently I have tried to open a window when sitting in the car with the ignition off in order to for example, take a photo, and by the time I realise that it won't open without the ignition on, I have missed the opportunity.

I am thinking that the door opening circuits are energised when the car is unlocked or single-locked and was wondering if I could somehow take a feed from there to power the windows? I looked at the circuit diagrams and there are various black-boxes involved, and that frightens me... So has anybody done it? If so then how, please?

p.s. Most recently I missed an opportunity to talk to a nice YL because the window wouldn't open at just the right moment, so you can see how annoying it can be!

Better option (IMHO) would be to feed the window fuse from permanent live rather than f** about with the wiring in the doors.

I thought the same, and nearly posted it.... Then I realised this is a D4, and likely does all the permanent/ignition live gubbins in some becm, so not just moving wires about.

Then, I though about I more, I'm not sure I would want them available on permanent live anyways...

That's why I was thinking that the door mechs would be a good choice - they are live when the car is unlocked or when it is single-locked, but not when it is double-locked. TheBECM is the reason I was asking the question - that sort of thing frightens me... I tried something similar on a skoda a while ago only to find that the window switches didn't actually control the windows - they just sent a signal to the ECU... grrr

different topic altogether. - what do you think these things are for? (arrow drawn on mobile phone - sorry) I mean the downward flaps that look a bit like spoilers, one each side at the front...

Possibly smooths airflow over the bottom of the suspension / wishbones when at speed?

My old L322 had similar fitted...

Yes, all about fuel efficiency and wind noise.

If the windows are under the control of the BECM you'd be screwed whatever you do, if the BECM doesn't want the window down the window ain't going down unless you bypass it and power the motor direct... but the amount of f***ing about with a somewhat complex wiring loom that entails is rather nasty, and blowing up the BECM would be a bad day out too.

hmm... Think I'll shelve that idea then... Thanks for the reality check!

How well does the FBH (fuel burning heater) work?

First - my traceable to national standards outdoor thermometer wot I found in the garden:20190103_152816.thumb.jpg.3c3d3c03fd30520a8c889655e2804370.jpg

To be honest I think it was colder than this, but the car agreed, -6oC

Now the car before running the heater as a 'single timed event' (which is a 20 minute (max) run)

20190103_151353.thumb.jpg.03ffc57160d7b856c1ba0576f5766457.jpg

 

Then a video of the FBH exhaust while its running (I can't upload this here as it's too large)

 

And finally - how the windscreen looked 18 minutes after the FBH started. Not bad eh?

20190103_153312.thumb.jpg.d591ec1e886e11af983ac269bcf367b2.jpg

 

It's interesting to note that on a cold day the FBH runs even if I just get in and start the engine and drive away - this means that I have warm air from the vents long before the engine has warmed up.

Also I think that the FBH just heats the cab unless it's VERY cold in which case it will preheat the engine instead.

Anything below 4° has the FBH kicking in...think I read that in my D4 handbook when I had it.

By the way, that's one very smart looking D4. The wheels and tyres suit it well.

Thanks! I think so too. The 18" wheels have 10mm more offset than the normal LR ones, which (combined with chunky tyres) really makes a big visual difference, and improves the driving experience. win-win really :)

It's the cheap bit of plastic **** that emits an audible warning (distinctive crunch sound unlike other alarms) to warn you that in another two inches there is going to be a ucking expensive crunch as the hideously expensive and utterly misnamed 'bumper' fails to bump anything and disintegrates into 17 pieces, some of which will be jammed into the steering, others underneath somewhere, and a few lost for all time in the bottom of the relatively shallow ditch you just dropped the nose into :huh:
