Otherwise it goes like a scolded cat and tows the van effortlessly.

You’ve definitely turned off DSC/stability control?

Yes and tried various modes. It did not dig into the sand it just "died"

What range were you in? High or Low?
What TR mode?
DSC off?

I'm confident I know the answer :)

Tombie I tried in sand mode of traction control with DSC off. High Range then low range. I then tried just normal road mode with DSC off. There were other D4's there. Some TD some SE. They all went up in low range sand traction control, DSC off, and let the transmission select which gear it wanted. Two cars had 19" with Maxis tyres, the others had compomotives with K20 as I do. We all had pressures around 15 psi. They all flew up. I lost momentum barely 1/4 way up where there was a sharp RH bend and a jump up. I had foot to the floor. This also happened when I was doing some driving in mud climbing up a hill where momentum was the requirement some time ago. The car just gets to a hard bit and suddenly power dissapears. The car does not stall but almost seems to go into limp mode. There are no codes on my Gap tool.

I wonder if the clutch pack in your transfer case is worn out....

Pressure does not decrease when venting gallery. Time for a desiccant and filter refresh. I knew it was due to be done soon.

The indy (Rova Range) changed the transfer case oil when I complained last time. Car has only done 100K and I dont do a lot of 4wding in it (mainly towing). If it is the clutch pack I am a bit ****ed off as the car has not done a lot of low range 4wding. But it is something I will discuss with Jason.

I wasn't aware you can do an EGR delete on a 3.0 litre, in which case if I am correct it begs the question whether the tune was done correctly?

Very good point, AFAIK no egr delete possible on the 3.0 TD/SD V6 without a comprehensive ecu remap. Not like on the 2.7 with blanking plates and emulators.

My EU4 2.7 was done with a BAS patch and blanking plates. Just putting plates in caused faults.
