"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

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.

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!

[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.

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.
