2018 Jaguar F-Pace 2.5 Sport warning says Exhaust Fluid Dosing Malfunction No Engine Restarts - what does it mean?

The temptation is to assume that the car is simply low on AdBlue (an additive that is sprayed into the exhaust of diesel engines to clean up their tailpipe emissions and make them less toxic). When this is depleted, the engine is programmed to warn the driver that the level is low, and then not to restart until the AdBlue has been topped up. This is possibly what the dealership did to remove the warning.

But there’s a chance that the AdBlue injecting system has a fault somewhere and the problem is not as simple as low AdBlue fluid. That’s why the error message has returned. Or, you may simply have a dud sensor that continues to think the AdBlue tank is empty.
