Diesel Exhaust Fluid (DEF) System Dosing Malfunction Detected

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

Legislation requires that DEF is continuously available to the Selective Catalyst Reduction (SCR) system. An Instrument Cluster (IC) message center warning is displayed if a fault is detected which prevents correct system operation.

There are two warning stages displayed in the IC message center, until corrective action is carried out.

STAGE	WARNING	MESSAGE	CAUSE
Stage 1	Amber symbol	No Engine Restarts Possible in 400 km/250 miles	DEF range <400 km/250 miles
Stage 2	Red symbol	No Engine Restarts Possible	DEF range 0 km/0 miles

Stage 1

Stage 1 is an amber warning symbol with a kilometer/mileage reference to advise fault diagnosis must be undertaken by an authorized Jaguar dealer within the distance range stated.

Stage 2

Stage 2 is a red warning symbol, this indicates the available distance, for a corrective action, has expired. The engine restart is inhibited and fault diagnosis is required to be undertaken by an authorized Jaguar dealer.
