Hello all, sorry if there's already a thread about this topic, but I couldn't find one.

I read through this very informative post: https://www.landyzone.co.uk/land-rover/disco-ii-air-suspension-–-the-definitive-guide.171995/ and have a question to the experts around here.

"The conversion to coils requires the re-programming of the SLABS ecu to turn off the air function, an additional cost at the dealer!"

I've got an issue with the ride height sensor and am therefore thinking the best idea is to switch from airbags to coils.

I'm currently in the Northern Norway, and it seems impossible to find someone who can help with the reprogramming (I've already learnt, I'll need my own Nanocom), so was wondering if it would be an issue to leave the reprogramming for now and drive back to my homebase before doing that.
 
A common modification when the rear air suspension has issues here in the UK although the consensus opinion is to keep and repair buy some owners as the vehicle.
As u have found out theres a a bit of info on this subject already on this and other forums, with luck u may and fined the definitive answer to your question:)

The programme is required when parts are missing therefore a illumination error displayed on the dash.
If you are going to fit steel springs the electrical isolation for the compressor will be required until u can u plug the diagnostic kitI, expect that could be a simple fuse removal.
As for leaving it and driving it to the UK sounds a bit iffy, depends on what’s happened at the vehicle rearI expect.

Im surprised theres’s no LR specialist I your part of the world :(

Hi, IMO that's definitely not the best ideea but if that's what you want then after the conversion unplug all the connectors in the compressor housing, remove relay R5 and learn to live with the SLS warning untill you program it for coils and be ware that it's possible to have some quiescent current draw over night but not a killer if the battery is strong
 
It will also affect your insurance when you tick the box saying..... "modifications to suspension" My quotes went up £2k when I ticked that box.....

Infact, not wanting to divert from the op thread, can anyone recommend an insurer that accepts this mod....Adrian Flux seem to get into a tizzy about it

This is mad considering how many Disco 2s have coils fitted as standard.:rolleyes:
Can't help but feel this is opportunism.

I agree with the opportunism but i'd not compare a vehicle which left the factory with genuine parts correctly fitted and tested with one bodged up by the owner or some mechanic using aftermarket or second hand parts so IMO there is some logic too in the increased insurance for a vehicle which was modified on the suspension, direction or braking system.

This makes very strong assumptions.
What if you paid a LR garage to do the change and certify it as such?
As I said, it is standard fitment on so many, like mine, paying them to do the work would be cheaper than the insurance hike!
And I am not sure how the factory would test every single LR disco fitted with coils. Except when it gets driven off the production line and onto the transporter!;):D
 
AFAIK the vehicles are all tested before they leave the factory and only a main dealer can certify a conversion, and dont tell me that somebody who prefers to fit coils instead fixing the SLS if it goes wrong cos seems expensive to do that would fit genuine springs on it(which BTW are around 130 a piece) or pay a dealer with huge prices for a conversion(a dealer would charge £80 only to set the ECU for coils for example) :rolleyes:

If I had air and it got expensive to fix I sure as heck would fit coils, and I'd pay for LR ones and it cannot cost £2000 to fit them by a LR garage.
And even if it did, don't forget the insurance costs, if these are real, would be repeated year in year out, not allowing for NCD obvs.
Again you are making assumptions about the type of person who would do it.
 
P.S.
Adrian Flux???

Not surprised.:(:(
My experience with them was with kit cars when I first got into them. I wouldn't touch them with a bargepole now.
Went with them I think twice before I sussed them out, and there are quite a few on here who feel the same. ;)

Forget Adrian Flux. Try the others, or threaten to move away if they don't get reasonable. ;)
 
I am not knowing of the D2;).
But this comes up often in the RR section.

Are you not potentially taking away the self leveling ability of the headlights? Potential MOT failure if the MOT testers were really switched on;)
TBH fix it to standard, once fixed and understood, it really isn't that complicated:rolleyes:.

I too am not really knowing of it on the D2 except that there are a lot of posts on here about it and problems with it.
Yet more unnecessary, electonically controlled carp.:(
Bit like ACE really only different.
Mine being on springs has headlight levelling operated from inside the cab. I don't know if those with air sussies have automatic self levelling lights or not. But if they do then.... whoops!... there is something else to go wrong.:rolleyes:

And for what it is worth, if my ACE plays up it'll be binned and replaced with ornery ARBs. And gas shocks. They sorted my D1 so it was even better than the D2 with ACE;)

I'm not saying you are wrong. There are cheapskates around who will do stuff that compromises their vehicles But then there are many others who will do things competently and get them checked by a competent person or pay the competent person to do it.
For instance, when I wanted heavier duty springs fitted to my D1, I got an LR independent to do it for me.
I'm pretty sure I'd have done it OK, as, as you probably know, I have been around kit cars for decades where springing really is an issue as all kits are lighter than the donor vehicles.
I even once wrote a very long article on springing for the Marlin Owners magazine, and that was scrutinised by all sorts of very competent engineers. ;)

Self levelling headlamps or self levelling suspension they are different so which?

My RR had self levelling suspension but over loading the boot would see the head lamps shining light skywards.
D1s didn't have self levelling suspension so was fitted with harder springs, but its still easy to over load the boot, and as a option manually levelling of its headlamps in a similar system the D2 has.

My two ‘recent cars’ Ive owned in the past 10 years, had headlamps that were self levelling, one car had HID the other LEDs and both headlamps had a servo that went through a self test when switching on the lighting, that function is part of the MOT, I believe.

The D2s never had self levelling headlamps.

Not true, if working correctly.
Put a trailer on with something on it, drive it park up and disconnect the battery. Then see how far you have to wind up the jockey wheel to get the trailer off. As the rear of the RR rises.

you need 1 or the other or manually adjusted headlights for MOT, do you not?
They amount to the same thing.
