DESCRIPTION
A design issue has been identified on 2012-2013 model year Range Rover Evoque vehicles within the listed VIN
range. While driving in wet weather conditions, condensation may build up within the engine Charge air radiator.
Following a rapid increase in engine speed, this condensation could be drawn in to one of the engine’s 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. In this mode, the driver noticeably experiences reduced power to accelerate until the engine is
switched off and then restarted. Furthermore, an engine warning message will display in the instrument cluster
message center and the Engine Malfunction Indicator Lamp may illuminate.
New components have been designed to limit condensation from building in the engine’s Charge air radiator to
prevent the restricted performance mode from initiating. Additionally, updated Engine Control Module (ECM)
software has been developed which changes the thresholds necessary to initiate the restricted performance mode
for this issue.
Service Action Q255 supersedes Q237 with immediate effect. Vehicles updated under Q237 require the rework
action detailed in Q255.
AFFECTED VEHICLES / OWNER NOTIFICATION
The VIN range of affected vehicles is CH000447-DH769903.
Owner notification is expected to commence the week of 14 October 2013.
WORKSHOP PROCEDURES
Retailers are required to check DDW to ensure that the vehicle is affected by this program prior to undertaking any
rework 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.

SERVICE ACTION Q255: SAMPLE OWNER LETTER
Service Action Q255: Water Induced Misfire / Restricted Performance
Dear Range Rover Evoque Owner,
Land Rover is conducting a no-charge Customer Satisfaction Program (Program Code Q255) for owners
of 2012-2013 model year Range Rover Evoque vehicles.
What is the concern and what will Land Rover and your Land Rover retailer do?

m
pl

e

Land Rover is writing to request that you bring your vehicle in to your Land Rover retailer for the
installation of new components and updated engine management software which will improve your engine’s
response in certain weather conditions. Specifically, during the course of extended driving (40 minutes or
more) in wet conditions, (such as heavy rain) when your engine speed is steady, followed by a rapid
increase in engine speed, it is possible that an engine misfire may occur. Your 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 driver has the
opportunity to stop and restart the vehicle. If this mode activates, the Engine Malfunction Indicator Lamp
may illuminate and an engine warning message will display in the instrument cluster message center.
Land Rover would like to install a grille to the front of the vehicle’s Charge air radiator and install a venturi
to the inside of the Charge air radiator (if necessary, depending on VIN) in order to prevent any
condensation from building and thereby prevent the restricted performance mode from initiating. We will
also install updated engine management software which changes the thresholds necessary to initiate the
restricted performance mode for this issue. If you have any concerns or questions, please feel free to
contact your retailer.
What should you do?

Contact your preferred Land Rover retailer and provide the retailer with your Vehicle Identification Number
(VIN) and request a service date to complete the work required under Program Code Q255. During this
visit, please take the opportunity to discuss any aspect of your vehicle’s operation or performance with the
Retailer team who will be pleased to assist you with any questions you may have regarding your vehicle in
order for you to get the most out of its advanced features.
How long will it take?

sa

The work will be carried out as quickly and efficiently as possible in order to minimize inconvenience to
customers and is expected to take approximately 2.5 hours, although your retailer may need your vehicle
for a longer time due to service scheduling requirements and vehicle conditioning.
Attention Leasing Agencies: Please forward this notification to the lessee within ten (10) days.
Moved or no longer own a Land Rover?
If you are no longer the owner of this vehicle, Land Rover would appreciate the name and address of the
new owner (if known); please fill out and return the enclosed return postage-paid card.
What should you do if you have further questions?
If you have any questions or concerns, please contact the Service Manager at your authorized Land Rover
retailer for assistance. If you have any queries or concerns that your local Retailer cannot address, please
contact the Land Rover Customer Relationship Center at 800-637-6837, Option 9, and one of our
representatives will be happy to assist you.

SERVICE ACTION Q255: TECHNICAL Q & A
Main Message:
During the course of extended driving (40 minutes or more) in wet conditions, (such as heavy rain) when
engine speed is steady, followed by a rapid increase in engine speed, it is possible that an engine misfire
may occur. The engine is programmed to react to this misfire by initiating a restricted performance mode
(i.e., reduced acceleration) to protect the exhaust catalyst, which means that the driver noticeably
experiences reduced power to accelerate until the driver has the opportunity to stop and restart the
vehicle. If this mode activates, the Engine Malfunction Indicator Lamp may illuminate and an engine warning
message will display in the instrument cluster message center. Land Rover would like to install new
components as well as updated engine management software which changes the thresholds necessary to
initiate the restricted performance mode for this issue.
Q1

Why is Land Rover conducting this Customer Satisfaction Action?

A

See Main Message above.

Q2

Can you tell me more about what is wrong with the vehicles?

A

The condition is related to water (condensed from humid air) collecting in the engine air intake system
when vehicles cruise for 40 minutes or more at around 50 miles per hour, in wet conditions such as
heavy rain when engine speed is steady. Thereafter, such condensation may be sucked into the engine in
the event that a rapid engine speed increase is demanded by the driver. In such event, the engine
monitoring systems will detect a misfire and employ restricted performance mode as a result along with
the Engine Malfunction Illuminator Lamp and instrument cluster warnings. The restricted performance
mode clears itself after the vehicle is turned off and restarted.

Q3

How would the customer become aware of potentially having this concern?

A

The customer will experience restricted performance of the vehicle while driving. The Engine Malfunction
Indicator Lamp may illuminate and an engine warning message will display in the instrument cluster
message center. The restricted performance mode will continue only until the engine can be turned off
and the ignition restarted.

Q4

Do the new components and software update and remedy the condition?

A

The new components have been designed to limit condensation from building in the engine’s Charge air
radiator to prevent the restricted performance mode from initiating and the software update has been
developed which changes the thresholds necessary to initiate the restricted performance mode for this
issue.

Q5

Have there been any accidents or injuries?

A

There have been no reports of accidents or injuries relating to this concern of which Land Rover is
aware.

Q6

How was the condition discovered?

A

The condition was identified through Land Rover’s retailer technical field reporting process.

Q7

What will Authorised Repairers do to the vehicles?

A

Authorised Repairers install a grille to the front of the vehicle’s Charge air radiator and install a venturi to
the inside of the Charge air radiator (if necessary, depending on VIN) in order to prevent any
condensation from building and thereby prevent the restricted performance mode from initiating. We will
also install updated engine management software.

Q8

How long does it take for the work to be completed?

A

The work will be carried out as quickly and efficiently as possible in order to minimise inconvenience to
customers and is expected to take no longer than 2.5 hours to complete. Naturally, due to retailer
schedules, vehicles may be required for longer.

Q9

How do I know if my Range Rover Evoque vehicle is affected?

A

All owners of potentially affected vehicles will receive a letter inviting them to contact a Land Rover
retailer for the work to be carried out.

Q10

Can I continue to drive my vehicle until it has had these updates?

A

Yes. If you are driving in wet conditions such as heavy rain for 40 minutes or more at around 50 miles
per hour at a steady engine speed, then take care to avoid a subsequent rapid increase in speed, in
order to minimize the potential of a misfire to occur.

Note:

Please ensure that any Press enquiries are referred to the Jaguar Land Rover North America
Public Relations office.
