1 month into ownership and the lowest I have run my fuel down is 16klms range left. Has anyone done the Seinfeld fuel test (aka Kramer and Neumann) to see how far the FL2 will go? SD4 SE Orkney Grey

I ran mine down to 5 kms out near Alice Springs. It goes into limp mode automatically when it hits that. I had driven from Boulia in QLD via the Plenty Hwy and was under 20 kms from Alice. I had a 20 litre jerry to put in. I had travelled a bit over 800 kms. Another forumite did the Simpson and knocked the sensor on his fuel tank which sent the car into limp mode when it was still 1/4 full.

I forgot to add that you are in big trouble if you run a new diesel dry. You can't just fill it up.

you will find that if you run the fuel/miles reading on the on the computer in the car to zero it will go to reduced power mode so as you don't damage the engine this means you have limited acceleration  rainy-city

In my diesel i got 7 kms of flat highway running after the range went to zero once
And 12 kms the next time
That time it lost acceleration and coughed to a stop at the bowser
On another occasion it coasted to a stop in the fuel station after 14kms
Filled up and it fired up without a glitch, 30 kms down the road it wouldnt go over 90kph
Probably had air in the lines still
Got to where i needed to go and shut down the engine
One hour later started it up and let it idle for 30 mins
Headed down the road without a hiccup
I tried to find the a speed it would top out at and gave up after exceeding the speed limit by 50%
Figured from that the air in the lines was gone

Know another who has run dry several times and all he does is top up from a jerry can, cranks it over a dozen times, with a minutes pause between cranks, and the engine always fires up.

One guy i know has used petrol as fuel a few times (in his diesel)
He drops the incoming quick release off the fuel filter (in front of the engine) and puts a compressed airline in the fuel filler spout (with a rag around it)
Connects up the air compressor and pressurises the tank slightly and pushes the petrol right through the system into a bucket.
65 litres later
He fills the tank with diesel and starts up the compressed air again, purging the lines to the filter with diesel
Reconnects the filter and disconnects the incoming connection to the fuel pump and starts the compressed air again and purges out the fuel between the filter and the pump.
Opens the compression nut on two injectors and cranks the engine over
Waits for a good squirt of diesel from around the injector lines where they go through the compression nut and closes them
Repeats for the next two injectors
Everytime it fires and the only drama afterwards was the engine wouldnt fire if shutdown immediately after stopping the vehicle
So he had to bleed two injectors again and the engine fires
Run the engine for 30 secs before shutting down and this trouble doesnt occur

IN short
If you run out its no big deal
The floats in the tank will prevent you from running the system totally dry
The engine will shutdown first
Fill the tank and in a worst case scenario bleed two or three injectors
(one 17mm open ender and a 10 mm socket needed for this)
And will be back to normal
The engine will fire and carry on

Seems the fuel systems on these things are pretty robust and generally idiot proof

Thanks for the info. I would be worrying about the fuel pump. The CRD pumps are extremely sensitive to poor lubrication and cost a motza.

I used to worry too
They are designed to run on ultra low sulpher fuels
This would mean lubrication (which is what sulpher did in days gone by) isnt such a big deal

I know of too many people that have run petrol through them and not had any issues
Including one bloke who put 10 liters in before he realised he had screwed up
So he hung up the bowser and put in 50 litres of diesel
Then bought 200mls of two stroke oil and added it to the tank too
The cashier must have really wondered what the vehicle had for an engine

A mate with a D3 spent 14k in a dealer after LR said no warranty now unless a dealer does the prescribed wrong fuel work on the vehicle.

His wife did it to their Audi Q7 and engine collapsed within a fortnight so he decided not to risk the D3 and got the work done

His boy has since done it to his D4
The local mechanic purged the tank and refilled it with diesel
35000kms later it has missed a beat (and it gets flogged everywhere)

Bl**dy hell An Audi Q7 motor plus 14K on the D3...He's been pretty unlucky. Sounds like if he fell into a bucket of tits he would come up sucking his thumb

I guess he figured he could only have so much bad luck
So when the D4 was fuelled worng he decided to risk it
And so far it look like his good luck was back

Interesting that he traded the D3 and the Q7 on the D4 and a Golf
Swears blind it was the best thing he ever did
