Starting from cold, after 50-60 miles, fuel gauge drops to zero and terrain selector light goes out. Car continues but with reduced power and eventual coming to a stop. Car starts again without a problem after a couple of hours. Fuel sender replaced but problem persists.

Lots written on forum regarding similar problems.

There is a technical bulletin about fuel gauge wiring problems.

When I had this problem I suffered erratic fuel gauge, and resultant engine limp home (as the car tried to protect itself from running dry) . FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

I have the same issue on the Range Rover, but was told that “they all do that sir”

Better luck with yours

Just wondering if anyone here know's of a quicker method of replacing the fuel tank sensor's on the fl2 2.2. Mine has now completely gave up the ghost & won't even start now after month's of erratic fuel readings & going into limp mode. Someone suggested cutting a hole under the seat about the pump/sensor's but this is a drastic measure me thinks. Any advice appreciated. Rob

You need to read the technical bulletin.

This is usually corrosion in the connections and not a sensor/sender problem.

I've not heard of any method other than dropping the prop shaft and tank etc.
The good news is that the repair parts cost is pence. FL2 HSE Auto Galway Green

If I probe pin 1 and 2 of the tank connector, I get a reading of ~300 Ohm. Perfect.

If I probe pin 1 and 6 of the tank connector, I get a reading of no continuity.

When I put in the connector towards the ECM and I probe this side, I get ~300 Ohm as if it forms a loop from pin 2.

Should I get a value between 42-1000 from the tank side of the connector?
