why have you got a DPF 0n a 2008 LR3

Because some markets had a DPF fitted from the factory. Just because its not on our UK spec cars doesn't mean its not on an ROW spec car

Are right that explains that 1 then as I wasn't aware they fitted them that early

maybe because 2008 came with a DPF...? So why the question and rolling eyes...?

Dutchrockboy - As you have an IID tool I recommend you download the fault codes and post them here. It will help with ideas on the problem

Stiff calm down it was only a question as I wasn't aware they fitted them that early & the post was abit confusing with profile being LR4 & post 2008 LR3

This morning it took about 1/2 minute2 to get the failure.
The engine was quite cold.
When the engine was warm it took 10 seconds.
It defenitly can be something with the EGR.
Can anyone tell me which one of both EGR´s to look for? Left or right?

@ Mikey,

how do i calibrate the reardiff? On the IID i only found the Reardiff Test button.

I logged the EGR values.

The EGR Valve 0 Position Looks a Little Wobbly.

After stopping the Engine you can see the "EGR cleaning cycle" which is not funktioning on Valve 0:

Engine System failure - SOLVED

I cleaned the EGR.
This is what the LOG looked like before cleaning:

The blue line is the right EGR that was stuck.

After cleaning the EGR is moving again. The Engine system failure is gone.

Out of interest, did you use an EGR cleaner on the system or physically remove and clean the valve?
