Well now that the old girl is serviced, just been playing with the IID this morning to try and get more competent with it.

I know I have to regenerate the DPF to clear the fault and sure enough it's the only thing coming up

I was looking at live values and specifically the EGR readings, when does the second valve actuate? I gave the throttle some beans and only the first figure altered, when you change to the graph view first wavey line second flat.

Also in the section for updates on ECU's, where it says update available, where to you get this? Stealer I presume!

Could someone in the know maybe explain some of this to me please?

Thanks as always..

I've no idea about the 4.4 v8, but csn only assume that the 2nd egr and turbo will not come in until the engine is under load.eg.driving it.
just a stab in the dark.

Sounds plausible, I just thought blipping the throttle might activate it Current: TDV8 (3.6) RRS HSE

I believe the second turbo on the 4.4 TDV8 doesn't start to boost until 2500rpm, so blipping the throttle would not be enough to generate a reading.
