Hi and welcome to loonyzone

There’s a video somewhere , I’ll see if I can find it for u

Alas I’ve got a D3 so alas not up to par with the D4

Think they call it a TSOV valve

Here’s a video of the pipe mod , also The members on the D3/4 forum is also a great place to find info

Here’s a bulletin

Hank you so much, for your effort, Now I got the idea.

I haven't got the error code yet, it just happened once last month, when I drive up the hill, I got the restricted performance and lack of power, I just think I need to check if the issue was from there.

Hi

Have done some some digging and found abit of info for u

Ref P2459 https://www.disco3.co.uk/forum/p2459-dpf-issue-177258.html?highlight=P2459

P00bd https://www.disco3.co.uk/forum/seco...est-course-action-162609.html?highlight=P00bd

Sorry I can’t help more because I’m not up to par

Ref the limp mode, mine done exactly the same, mine was a broken jubilee clip on the turbo intercooler hose which caused limp mode

But urs is different having twin turbos

Have a read ref then secondary turbo

Ideally u need a really good code reader with these vehicles, always best to buy ur own as it allows u to then check live data

Hope that helps and plse let us know how it goes

7 months ago and he never bothered to come back or let anyone who had tried to help him know the outcome. Poor form really. Clearly only joined to get HIS issue fixed, not to share or participate or help others.
