LM 322 looking for a real expert

Steven911 · Aug 27, 2023

Dear members,

two years ago I deleted the AGR and DPF (software + mechanically+ balnking plates).
For the last two years the car ran perfectly, since now!

My Range Rover LM322 / 2008 is now showing following symptoms:

-While starting the engine idles at 500 even though I push the pedal down the revs do not go up. The car is not drivable as there is no thrust.
I have to mention that we have changed the following parts:

-New turbos
-new diesel filter
-new fresh diesel
-new battery
-new turbos hoses
-new coolant

Akward is that the car shows this symptoms when I drive it for 30 min and then want to start it again, meaning the engine has to be warm/hot. Once the engine is cold everything works pefectly. Since now nobody could find the error.

I will post a video of the error below.
I would be very thanful for any hint or tip.

Thank you a lot
Steven

I'm no expert but what diagnostic tool are you using, is it LR specific?
I didn't know they did a 12 cylinder.

Also what voltage do you have before starting?

kermit_rr · Aug 27, 2023

I'd be checking the battery voltage, ignition off, ignition on without engine running, then voltage with engine running.
It looks like a low voltage problem causing errors in the different ECUs

Steven911 · Aug 27, 2023

thank you for your answer.

The battery is brand new, voltage before starting 12,8. After starting 13,7 volts.

best regards
Steven

lol, plus 1 as also noticed that

looks a cheap scanner and wonder how many of them codes are historic

What voltage is it with the ignition on? It could be dropping very low during cranking. Sometimes you get a duff battery. Has it been fully charged with a mains charger?

Wonder if a dirty / blocked map could cause limp mode ?

ref P006C MAP - Turbocharger/Supercharger

may I pick ur brains plse

always thought that deleting the DPF and EGRS would fail an mot test , along with that if an insurance company would refuse cover if it’s been removed

just wondered if that was true , plus dont Know if it’s the 3.6 or 4.4 , many thks

This is a bit confusing.

If it's visibly altered then it will fail. It's also illegal as far as I'm aware to remove a dpf.

Egr blanking is not good for the 4.4 because it's necessary as part of temp regulation and regen of the dpf

It could be a red herring, though a sensor could be failing as it gets hot and working as it cools off again.
The battery voltage could also recover in the time it takes to cool off

Does this apply in Germany ?

many thks as always

funny enough heard that on the D3 forum where someone had a DPF and wanted to blank the egrs , was also told the same because of as u say about the regen mode

thks again

As the diagnostics think your engine has 12 cylinders, I would say that the list of faults is rubbish. You need L322 specific diagnostics.

As Germany is in the EU, I would say yes

I'd start checking the earth cables for any corrosion
