TSB Document:

Affected Component: ENGINE (PWS)

Summary
DESCRIPTION OF ISSUE: A revised engine management system (EMS) calibration has been developed to improve the robustness of the emission control system of TDV6 3.0L diesel vehicles within the listed Affected Vehicle Range. Specifically, the key improvements comprise a number of revised driver instrument display messages. These include the status of the Diesel Exhaust Fluid (DEF) system as well as an optimized emission control strategy for the extended operation of the vehicle under demanding conditions such as sustained high-speed driving, aggressive acceleration, or heavy towing. As a result to this change, it is expected that customers of certain vehicles who regularly operate their vehicles under such conditions will experience a noticeable increase in the rate of consumption of DEF. An Owner?s Handbook Supplement for these vehicles (Range Rover Sport [L494; 519971-571257; 617562-643823] and Range Rover [L405; 219083-274090]) is also included in this program.
