Hi all, Newbie here with a problem.
FL2 td4 07 170k with a reoccurring fault.
Started with message on screen terrain response system faulty, fuel gauge and range drops and goes into limp mode this was after driving 10 miles approx.
Had both senders changed but still have a fault.
Now on startup within a minute or two get the message special functions off and fuel gauge drops and limp mode.
Anyone experienced this?

Could be an earthing problem. I think I have seen this type of post before & it was suggested to put an extra earth strap from battery to somewhere near the starter motor on engine.

Have not done mine yet but will have to get round to it soon, mine is 2007 as well.

Pete, I would check that they fixed the known fault with the wiring connector in the tank, when they replaced the senders. 2005 D3 2.7 Auto

Thanks for the replies.
Sorry I think I've posted in the wrong section maybe it could be moved to technical....Re the earth I ran a secondary from the battery to the chassis.
The wiring in the tank was modified with the approved crimps as I didn't think soldering stainless wires would work to well.
I've read that the brake light switch might be worth changing along with new bulbs in the rear lights. I'm thinking of checking the tank sender loom at the bcm back to the tank for continuity? Loving the truck but not the faults....

1. The second earth lead needs to go to the starter motor, not the chassis.
2. Your senders/tank wiring repair is almost certainly causing the fuel gauge fault. When it drops to zero it will put you in to limp mode to help prevent running out of fuel. Need to look at it again.

Hi Bob will look at doing the earth....
The tank had new oem senders a&b and was preassebled in a spare tank.
Resistance readings where spot on at the top connection from the tank. I tested the new senders out of the box so I don't think there's a problem that end.
Wonder if the bcm has a dry joint?

Possible but not seen any other on the forum with such. More likely to be a connection in or on the tank.
Is the gauge fault always there? Or just with a low tank level?

1/4 tank we drove 8 miles back from the Indy b4 it went into limp mode.
Have since filled to nearly 3/4 of a tank same thing happens.
But next day fault will appear on tick over within a couple of minutes.
Will startup later to see what it's doing today.

OK just started her up an no change. With the fuel sender fault is it normally special functions off followed by the gauge drop?

Take a look at this thread: “Freelander 2 2012 fuel / balance pump problem?”. There are also other links in it. May help you. Mine was fixed by rewiring the senders in the tank, so not sure where to go next.

If you look at "inventive way to deal with difficult problem" I was show hove to make the ecu think there was a full take. That was back in 2016 car has ran fine to this day. Not a fix but is a easy way to rule out a problem. Ian

Ian, are you saying that you used this fix, or that your tank problem never recurred after it cured itself?

I had one occasion where the tank read zero and took a long time time to slowly come back up to full - this was after being parked nose down on a steep incline. It didn’t go into limp mode (or I didn’t notice) and I have always wondered if this was a precursor to the dreaded tank problems.

I wonder about making up a version of Andy’s solution (using the female end of that coupling and the wires soldered to the resistors) and keeping that in the car on a “just in case” basis. 2005 D3 2.7 Auto

Interesting idea with the resisters but as I have renewed the senders and crimped the 2 wires between the senders I'm sure that side is ok now. What I'm trying to establish is if there's a fault in another area as I get the special functions off message b4 the gauge drop. Next thing im going to try is unplugging the bcm and testing the resistance at the multiplug back to the sender.
I guess I'll have to disconnect the battery 1st (another worry)
I wondering if there's a break on a sender wire in the loom.

Just read JK's post had a loose connection on his throttle body after replacing so I re made all the connection on mine and get no message or gauge drop.
Will test drive later and report back

Well I'm keeping my fingers crossed
