2006 2.7 auto limp mode
Hi all, done lots of reading and some ace advice on here so thanks for that.
I have a 2006 disco with a long list of fault codes, but long story short its going into limp mode.
Turning it off and on resets and drives fine for a random amount of time until it goes again, not noticed any specifics as to when it goes it limp mode ie under braking or hard accelerating or any particular rpm range its totally random.
I believe the code putting it in limp is p132b or p0562 theres also a p0324 code.
The remote fob is also not working, have tested key and is transmitting fine so must be a fault in car the central locking on button still works.
So far things done-
Brake switch ordered will be fitted as soon as arrives
Egr’s blanked
Air suspension all works adequately so im not too fused by those codes.
Car runs and drives perfect until it goes into limp.
Battery reconditioned and tested and all good.
So after looking up these issues i see lots recommending to check the splices under passenger tread plate which i will be doing asap.
Does anyone have any input toward the fault codes i have and any other suggestions of things to try?
Thanks in advance

I would check the turbo actuation arm thru the front left wheel arch,
using a suitably bent bit of coat hanger wire.
If stiff buy wynns vvt cleaner puple bottle.
Inspect air filter, and replace if not serviced recently

Using the manufacturer approved diagnostic system, check for turbocharger related DTCs and perform the relevant corrective actions Check the intake system for blockages/leaks.

Great info thanks, sorry it was p0234 turbo over boost condition.
Might just buy the VVT cleaner either way for sake of £10 and give it a go.
Will check actuator arm asap too

I’m no engineer but I’m not sure how much of a product put into the tank diluted then
Compressed and burnt will be remaining in the exhaust gases to clean any turbo vanes or indeed anything once past the exhaust valve?Discovery 3 tdv6 HSE 2007

The remote failure will be caused by a wiring fault and is easy to repair

I have found most variable vane turbos have siezed due to rust expansion siezing the mechanism not due to soot. No amount of additive will cure this.

Hi I am qualified mechanic running a successful small Indy garage, we use tank additives to clean petrol and diesel systems and whilst you don’t get the push you in the back of the seat performance differences you only really notice the lack of problems when using (quality ) additives 👍Current fleet

I have used a variety of products to clean the fuel system by putting them in the tank. Was a fan of pouring redex down carbs to watch the smoke cloud years ago.
I can’t see how a product inserted into the tank to be burnt can clean a turbochargers vanes though?Discovery 3 tdv6 HSE 2007

I used it in mine and it appeared to sort it.
I think it must increase the exhaust temperature to burn off soot
Or produce some chemical post combustion.
I Was sceptical. But £10 is better that taking a turbo off one of these

I think you have to at least try it for that price.

Thanks all
So its looking likely to be a turbo fault causing the overboost.
What is a realistic amount of hours i should be looking to pay for someone to swap the turbo please?
