THIS SERVICE ACTION IS VALID FOR A LIMITED TIME ONLY
AND WILL EXPIRE ON 30 NOVEMBER 2014
SECTION: 303

Service Action: Engine Control Module Reflash
AFFECTED VEHICLE RANGE:
Range Rover Evoque (LV)

VIN:
Model Year:

CH000447-DH721750
2012-2013

CONDITION SUMMARY:
Situation: A design issue has been identified on 2012-2013 model year Range Rover Evoque vehicles within
the listed VIN range. In wet driving conditions, following a rapid increase in speed after steady state driving
modes, condensate from the charge air cooler can build up inside the air induction system which can be drawn
in to one of the cylinders causing the engine management system to sense a misfire. The engine is
programmed to react to this misfire by initiating a restricted performance mode to protect the exhaust catalyst,
which means that the driver noticeably experiences reduced power to accelerate until the next ignition cycle.
Furthermore, the Engine Malfunction Indicator Lamp may illuminate and an engine warning message will
display in the instrument cluster message center.
New engine control module software has been developed which introduces an alternative restricted
performance mode where engine performance, under certain conditions such as those triggered by the water
ingestion described above, will lessen the degree of restricted performance employed. It is highly likely that
the condition will clear when the ignition is cycled.
Action: Retailers are required to HOLD all affected vehicles in the above VIN range that are in their control
and refrain from releasing the vehicles for new or used vehicle sale pending completion of the rework action
detailed in this Technical Bulletin. This rework action should be performed at the conclusion of the PreDelivery Inspection (PDI) process. Vehicles already in the hands of customers should be updated at the next
available opportunity.

PARTS:

TOOLS:

REPAIR PROCEDURE
UPDATE THE CONTROL MODULE SOFTWARE
CAUTION: Ensure all ignition 'ON' / ignition 'OFF' requests are carried out; failure to perform these
steps may cause damage to control modules in the vehicle.
CAUTION: A Land Rover-approved Midtronics Vehicle Power Supply must be connected to the
vehicle battery during IDS diagnosis / module programming.
1. Connect the Land Rover-approved Midtronics Vehicle Power Supply to the vehicle battery.
2. Turn ignition 'ON' (engine not running).
NOTE: IDS must be loaded with IDS-DVD131.08 v.119 or later.
3. Connect the IDS to the vehicle and begin a new Symptom Driven Diagnostics (SDD) session.
4. Follow the on-screen prompts, allowing SDD to read the VIN and identify the vehicle.
5. From the Session Type selection screen, choose 'Campaigns'.
6.

NOTE: If a pop-up requesting Emissions level is displayed, select ‘Federal’.
Select 'Run' to perform the ‘Configure existing module - Powertrain control module' option.

• Follow all on-screen instructions to complete this task.
7. Exit the current session.
