"Restricted Performance"

[Lukeis]

I guess when it rains it pours..

Recently I've ordered new LCA's, also doing the sway bar bushes and links which should eliminate the creak as I turn corners, these are being fitted on Wednesday.

Also lately I've been getting a "normal height only" warning which seems to be intermittent as it comes and goes over the past month or two, I'll deal with this one soon.

The main one which has me concerned is that two days ago and about 4 times since (out of about 15 trips) I've been getting a red "restricted performance" message on the dash. Does anyone know what this means???

I've not got an IID tool but finally I understand why people have been so supportive of owning one.

Any tips to check or is this simply too vague to call without taking it to LR for a look?

Having three issues at once the week after buying a new house is less than ideal!

Join my club. On my way up the West Coast to Ningaloo mine started doing that. IidTool told me P006A which I understand to be a discrepancy between the MAP and MAF sensor post turbo, hence leak somewhere. I've already had the drivers side air intake / intake plenum replaced 60,000km ago so I guess it's somewhere else. You'll need an iidTool to have much chance at knowing where to start to diagnose it in my opinion. Good luck.

they do need cleaning from time to time ....try that first

IidTool told me P006A which I understand to be a discrepancy between the MAP and MAF sensor post turbo, hence leak somewhere.Not necessarily a leak as it could be caused by the secondary turbo's inlet isolation valve sticking. Grit can build-up between the housing and the lever on the butterfly shaft (other side, out of sight) causing it to not operate smoothly but some water or lubricant sprayed onto the shaft/lever then the lever operated by hand will free it.

Alternatively the solenoid valve that controls the airflow that operates the valve can become sticky. This valve is located at the top of the engine near the front. A replacement valve is needed if the current one is sticky.

[DiscoJeffster]

Thanks Graeme. I'll take a gander. I have also had the 'KIT turbine shutoff valve' done at the same time as the intake. Is this the part you're discussing? I have to say, the dual turbo setup on these is complicated! [emoji2]

[Graeme]

Yes, the same valve and another of the several descriptions depending on what LR publication one is reading.

Somewhere on the forum is a directory of owners with diagnostic tools. Find someone in your area to read the fault codes for you.

[Lukeis]

I thought a tool was assigned just to your own car? As in linked to that VIN? I'll check it out, that would be helpful

You can pay a nominal fee to add another VIN to an existing unit single VIN unit.

Here's the link to it.

For those wondering, the Gap IIDtool is VIN locked but you can transfer ownership. It can still be used to read faults on other vehicles. Here's a reply from their FAQ area.

Transferring a unit costs 25 GBP. Once payment is received (web-shop), further instructions will be provided.
An IIDTool BT can be transferred to any vehicles while a regular non BT unit can only be used on the same vehicle type it was destined for. A regular non BT IIDTool firmware can be made to work on another platform by changing the firmware at a cost of 55 GBP.


The Nanocom is not locked and it's simply an e-mail to change ownership.

The diagnostic functions of the IID Tool are NOT VIN locked - you can plug an IID Tool into any vehicle (of the same model) and read / clear faults in all vehicle systems. [wink11]

Scroll down on the page linked and you will see what you can / cannot do with an IID Tool. IIDTool - Gap Diagnostic (https://www.gap-diagnostic.com/products/iidtool/)

Thanks for the clarification BMKAL. I read "Full Diagnostic" as diagnosing not clearing or fixing. :oops2: If all else fails read the instructions I suppose. Should have looked down the page a bit further. It's the advanced functions that are restricted.

[DiscoJeffster]

Wow, BMKAL. I didn't realise that. In that regard I'll get my name onto the list then.

[Lukeis]

Looks like the Fault "Restricted performance" is coming from a split in a pipe... see pic. If you look closely you will also see the big split too.

The shop has quoted $350 to replace the pipe (part only) plus an hours labour but I'm sure there is a cheaper source only I'm unsure which is the part number?

Here are the numbers on the pipe:

>CR<
5H22-6K863AA
PNH 500025
D05WB 45/10

Even better if you can go a step further and recommend somewhere to buy one!

Look for silicone replacements. Far tougher and no side effects. Some companies make sets for the different engine combinations.

[Lukeis]

Thanks, I'll look for one now.

I've since worked out the part number is the PNG500025 number for anyone else who is interested.

From the UK
Cheapest Part is $35 plus $50 postage (non LR)
Genuine LR part is $79 plus $50 postage

From AUS
Cheapest Part on eBay is $90 Plus $18 postage
Genuine on Ebay is $175 Plus $18 Postage

Either way, a lot better than the $360 I was quoted an hour ago!

It's possible to get the genuine part delivered for about $100AUD.

Thanks kelvin, from overseas I presume?

Sorry I forgot those prices included VAT

Yes, from the UK.

No VAT to pay as export outside of the EU.

Luke - if you want an original LR hose, I have one in my garage - you can have. Only had about 20,000km on it when I changed over to a silicone hose. Only takes about 30 mins to swap them over - hardest part is getting the plastic plugs off the bottom shroud, near radiator.
Cheers,
Rob

[Lukeis]

Thanks jonesy, that was a really nice offer but I already received mine and installed it today.

You are correct, it takes nothing to install!

Our 2010 3.0 tdv6 has had this restricted performance going on for some time with the orange light showing intermittently, particularly after reversing??

Anyway, now the warning is showing red intermittently and chopping performance dramatically. Some good tips on this thread of how to beat the P006a error but what is the hose shown on page 2? Bottom intercooler hose?
Thanks

[Lukeis]

It's the intercooler hose. About a meter long and 3inches thick (basically the bigggest pipe in the engine bay).

It goes from the top of the engine on the drivers side down to the very bottom to where the radiator is. Access is easy and only has two clamps to get the pipe out.

Check for leaks/cracks

Awesome, thanks for the info

So took the Disco to the dealer for the diagnosis and they have come back with the drivers side inlet manifold being cracked, which is fair as there is oily soot all over the RHS inlet.

Now the fun part, $6625 to repair.[tonguewink] $176 per hour for labour, holy well paid mechanics Batman.

I get the manifolds, do both because the other will fail, but they are saying the fuel injector pipes both side and the rails both sides are all single use couplings so once they come apart, cannot be re-used.

Can anyone shed any light on this as it is 70% of the parts cost and they just look like nut and olive fittings to me.

[Graeme]

The parts catalogue shows injector refitting kits containing a new pipe, new gasket and o-rings.

[DiscoJeffster]

Having been through this with that manifold, yes, the manual lists fuel fittings as one use. They are under extreme pressure so reasonable.
Mine was around $2500-3000 for one side only. I would not do both. Do just the fail one. There is very little shared between both sides so you're not really saving money by doing both at the same time. I've run for another 80,000km on the original passenger side manifold since the drivers one failed. If the idea of dealing with it again bothers you then do both but I'd suggest you will probably survive for some time. It seems to be the driver side one that fails mostly.
