I don’t believe I’m getting any movement from the back. It goes in to extended mode as soon as I try to lower it.

I’m unsure about how long I’ll have it for. It depends on how much it costs to fix it

Hi

Do u ever get this way plse, swanley kent

If u do can plug my diagnostic reader in FOC for u , alas can’t do the recalibration as it’s locked to mind but happy to try and pin it down for u and save a few bob along the way

I think I might still have my old rear valve block , nothing wrong with it when I took if off, I just replaced 2 x valve blocks and thought I might as well replace the last one, lol

Just know what it’s like chasing faults and pulling ur hair out , inc what outrageous fees some garages want to charge

 

[bedfordlr]

Unfortunately I’m never over that side of the country.

I’m booked in tomorrow morning 8.30. An hours labour at £110

 

[bedfordlr]

The car has been in, and I feel a little deflated!
I believe I’m supposed to be concentrating on the red section?! So bit EGR valves are shot - I knew that anyway. The rest... I’ll decipher slowly!

Hi and many thks

Are u able to turn the report sheets plse, finding it hard to try and read them

Many thks and can then go through them one by one

 

[bedfordlr]

Now that is a task I can do!

Hi

Does indeed look like a wiring issue to the rear valve block or the valve block itself

However it seems as though the rear height sensors arnt being told at what height to go because of the general electrical failure

Did u find that rear wiring connector by the back wheel, that’s where I would be looking first

Also If u look on This forum https://www.disco3.co.uk/forum/index.php, u can out all the codes in and will come up where other people have had that issue


As a side note did they attempt to re calibrate ur suspension or didn’t bother

 

[bedfordlr]

Any ideas what may have caused the general electrical failure? Wouldn't be as simple as a fuse?

I'll look at getting a replacement rear valve block and trying that first then.

I'll have to have a test of the voltage coming off the rear height sensors is? Did you mention 5v?

As far as I'm aware they didn't attempt to recalibrate the suspension, although I am certain that the suspension is lower than what it was when I drove it there!

Hi

Is normally wear and tear or where a wire has rubbed against a chassis pair , assumed u checked all the fuses

The connections I’m aware of are , by the back wheel and 3 x connectors behind the passenger side wheel arch liner

Yes 5 volts , however it’s reporting an electrical issue for both sides

This will show u where everything is

If u think it’s dropping the best thing is to test it over night , pull fuse F26 from the engine bay, then see what it’s like in the morning , see if it’s dropped

Know it can be difficult and time consuming going through the entire system, that’s what I had to do, I had electrical and pressure drop issues

Plse let us know how things go, also check out that other forum as it has a massive amount of information and are also very helpful

 

[bedfordlr]

Thanks for your help so far, I’ve been away assessing my options for a few days and have come back and started stripping parts off in order to get to the root problems.

Working on replacing the EGR valves, new discs and pads ordered.

Compressor has been removed tonight, it looks fairly new to me - the garage mentioned it looked new and a knock-off. I’ve no idea what the OEM looks like...?!

 

[bedfordlr]

Right, I’ve taken what I believe is the compressor dryer apart... I’m in no way an expert, but I’m not sure it’s supposed to look like this inside.....

 

[bedfordlr]

Also, the battery read 12.08v across the terminals with a meter - assume all is ok with that!

Hi

If u don’t mind me saying , if u register on the D3 forum there may be someone near u who can plug a diagnostic reader in for u to get live data

Otherwise and I don’t mean this disrespectfully ur be chasing ur tail and not getting anywhere

That compressor looks like it’s been rebuilt, can also see some silica in the dryer pipes ,

Battery voltage , is that without the engine running , really need roughly. 12.4 volts , what is it with the engine running plse

Having a reader plugged in will save I put a world of pain and the guys on the D3 forum are extremely helpful

Alas shame ur not closer as I would have helped u where I could go through it,

Know that’s not much help, but at least having someone help with a reader , also won’t be anywhere near what a garage would cost

Plse let us know how u get on, system needs to be tested methodically step by step and once again don’t mean that disrespectfully

 

[bedfordlr]

Decided to divert my attentions elsewhere and have spent the best part of a week removing the drivers side EGR.

In my amateur opinion, it looks like it’s in need of a replacement, hence the error on the report?! Will work on getting the passenger side off now.

Hi again,

It's five months later, and the LR3 is still sat on the drive. But we are closer to seeing it healthy!

So far I have;
-replaced both EGR valves
-replaced the rear EAS valve block
-purchased EAS Control tool
-stripped and rebuild the entire compressor
-left the car sat so long that the turbo actuator seized
-unseized the turbo actuator

Took the car for a good run the other day, and I am SO close to the end now - I can see the light at the end of the tunnel.

The last remaining issue I have is back with the suspension - I thought I'd sorted it, but alas. Front works as it should, the rear however, I dont believe is exhausting properly. Now, I'm pretty certain I had this fixed a while ago - could the exhaust have seized (I am contemplating stripping the compressor again). Could I have crossed the inlet and outlet valves on the rear valve block? I do keep getting a C1A13-64 (pressure not decreasing when venting gallery) error.

Any help would be greatly appreciated?

Dan

Hi dan

Looks like you’ve been busy , hats off to u as I know what it’s like to do these jobs

Must admit I tried to rebuild my air compressor then in the end bought a new Dunlop one k the back should raise first

Here’s a suspension manual if u haven’t got one, so u can at least see what goes where

http://media.disco3.co.uk/gallery/albums/userpics/15405/Land%20Rover%20factory%20D3%20air%20suspension%20description.pdf

If u have to remove the rear valve block again the trick is to use a stubby spanner , landy in off road height , wheel off and axle stand as please don’t put ur hand in there as they do and will drop , not trying to tell u how to suck eggs but when I first had mine the suspension dropped with the engine off, brown trouser moment

Great to see the updates and plse let us know how things go

As a side note , my suspension was in a terrible state , fitted new, air tank, compressor , 3 x valve blocks as when I rebuilt them they wouldn’t hold vaccum when I tested them, so rebuild seals weren’t sealing properly , then lastly new front struts , drives like s new vehicle

Main issue with suspension is when the silica turns to dust and goes everywhere , I ended up using an air compressor and blowing every single line out , plus cleaned the air filter for the compressor that sits in the boot locker, LH side as u look at the disco

Good luck

Evening!

Another weekend away meant no work on the LR. But I’m back now, and the compressor is off.

Can you give me any clues as to how the little rubber exhaust work? I’ve taken it out, and I’ve another one with holes in.

Thanks in advance
Dan

 

[Big Sandy]

Just read through this thread. Quite a saga, good on you for sticking with it. Kudos @bedfordlr

Wish I could offer advice, but these animals are way out of my ken.

Big thanks to @gstuart . What a star.

Hi dan

How u getting on, trying to think of what this rubber exhaust is

If I can help in any way plse feel free to Give me a shout

Alas if i may say ref The air compressor I tried to rebuild mine but was too far gone , bits broke and ended up fitting a new one
