Thread: D3 high speed extended mode

Been away for a week - on a slowwwwwwww connection - so didn't get to comment on this thread!

I had a very similar experience when I broke the air-compressor mounting bracket on a rock in Harvey. The car jacked itself up to extended height, gave a suspension fault error and stayed there. I drove back to Perth, cleaned the mud off, re-plugged the connectors around the pump, went to bed and everything was reset in the morning. Never happened again .....

I use the shortened rods when on long sand treks or rock-climbing. They're relatively easy to use. Like every man and his dog, I'm also working on a module that would electronically reset the base height, but it's proving to be more difficult than we first thought

Still, it _is_ possible, so I'll get it eventually ............

Cheers,

As I've commented before in many forums, i would like high speed off road settings, the Matzker package is just too expensive @ Euro1600 (AUD $2700).

Hi there! Newbie here, with a RRS that also needs this mod when it comes out.

A few questions sprung to mind reading this thread:

The Matzker kit sounds expensive but how does it compare to a lift on a coiler? Is it difficult to install?

Can the dealers, when re-calibrating the suspensio, not enter higher base values for each mode - so normal height is higher than before?

Will the CV joints take the abuse - and has anyone performed a 'diff-drop' to counter the extreme angles?

Cheers!

Here is some more info that may be of use: (from rangerovers.net, RRS section)

Yeah, but my understanding is that it's not something you can get done at dealerships, or a friendly LR indy shop, even if equipped with the latest T4/IDS software. Adam (Off roving) went through a buddy of his at LRU (Land Rover University), using a corporate version of the T4 Testbook - not locked down like the dealer/repair shop version - and with that software he was able to digitally recalibrate the system to provide +1"front and +1.5"rear lift in all suspensions modes. But unless you also happen to have a buddy working at LRU, you'll be SOL. The "regular" T4 software provided to dealers and indy service dept.s doesn't allow such changes to be implemented.

The thread is here: RangeRovers.net • View topic - 2" Lift Kit: Raising the air suspension permenently

So you can't use something like this?

Extended Profile Selector

Nah, something to do with how the CAN-BUS system on the RRS /D3 works.

Leo,

The dealers can recalibrate the system, but they won't set it to anything outside of the std operating parameters - warranty/liability and all that. At this stage the shortened rods still seems the best option. The extended profile circuit Ron linked to relies on the common cable return from the sensors, but the D3/RRS circuits are independent, so a lot more fiddling is required.

There was talk of adding a module to the Faultmate diagnostic scanners (from BlackBox) that would provide the re-calibration facility, but I don't know if this is present yet in their latest software patch.
