Hello XJL forum ...
im very new to the Jaguar forums ..
my names Rob ...looking for help ..

im about to buy a 2014 Jaguar XJL portfolio..
i took it for a test drive last week ...it sort of broke down ...no power after 1 mile ...would drive but slowly gaining revs slowly ...limp mode I believe ,...
ive now heard back from the dealer ....it appears that the XJL has a system that when the fuel is below 50 miles in the tank it goes into limp mode ??!!

Has anyone else had this happen or is this just lies ...

its a 2014 XJL ...with 24000 miles on the clock ..
please help !!

kind regards
Rob

 

Total lies! My 14 XJL has gotten that low plenty of times and never that issue. RUN away from this one! This is not a car you want out of warranty with obvious problems.

 

Noting your location, was it the 3.0L diesel?

Mine does go into limp home mode with about 20 miles left showing on the instrument panel gauge. The car still works (albeit in restricted mode) and the orange warning message comes on and persists on a restart until fuel is added to the tank.

[ edited to add detail ]

Reading the workshop manual on TOPIx, the diesels will simulate a run-dry procedure when the tank is low. It provides the symptoms of the vehicle running out of fuel and the driver will perceive it as such, and at 4L left will cut out completely.
Based on my observation that it happens with my car around the 20 mile mark, and the 77L tank gets me 460 miles, that 4L indicated in the workshop manual is around 24 miles of fuel left. I think that 77L volume excludes the 4L reserve that always remains. (Obviously "miles of fuel" is mixing distance with volume so makes no sense as a unit of measurement, but hopefully you get the idea.)

 

The fuel is used to cool the pump(s) so running low is not ideal if you want it/them to last long term.

 

Also keep in mind that if it is a diesel engine, running the car out of fuel is really bad on the injectors as it uses the fuel to lubricate the internals. You can liken it to running the engine with no oil in it. It will do it for short periods of time. But, it causes a lot of damage in no time flat.

The gas engines do not exhibit this condition. I have taken mine down to 0 miles left with the car not showing any signs of restricted performance. But then, I have the 5.0L gas/petrol engine.

 

 

lol - uh how exactly do you run an engine without any fuel again?

 

JagGate, I get to 0 miles on the "distance to empty" reading on occassion. The system is set up to still leave you a little bit of fuel even when the car tells you that you have none. Do I recommend doing this all the time. No. But, it is nice to know that if you are in a pinch, you have a few more miles than what the car says you have.
