SERVICE PROGRAM BULLETIN
APPLICABILITY:	2015 MY WRX 2.0L DIT Models
NUMBER: WQW-58R
2014-2015 MY Forester 2.0L DIT Models
DATE: February 10, 2016
REVISED: October 7, 2016
SUBJECT:	Engine Control Module (ECM)
Reprogramming
INTRODUCTION
Subaru of America, Inc. has determined that vehicles affected by this Service Program require ECM
reprogramming.
This bulletin includes the service procedure for diagnosis and repair of customer concerns involving
engine idle roughness or, in some cases, engine noise and/or damage resulting from spark knock
(pre-ignition). The Engine Control Module logic has also been optimized requiring the ECM
reprogramming.
The new logic optimizes the ECM for control of the following parameters:
•
Change to Fuel Cut control when fuel level is extremely low / near empty
•
Change to improve idle smoothness / quality
•
Change to boost pressure control under wide-open throttle (WOT) conditions.
Under certain high engine load driving conditions, spark knock can occur which results in elevated
cylinder temperatures and pressures. Over time, excessive erosion of the spark plugs and possible
damage to the pistons can be consequences of continued operation with these conditions present.
AFFECTED VEHICLES
•
Certain 2015 model year WRX 2.0L DIT (Direct Injection Turbo) vehicles
•
Certain 2014-2015 model year Forester 2.0L DIT vehicles
Not all vehicles listed below are covered by this service program. Coverage for all affected vehicles
must be confirmed by using the Vehicle Coverage Inquiry function on subarunet.com. This data is
scheduled to be available in the system when owner notification begins.

RETAILER AFFECTED VIN LISTS
Each Subaru retailer will receive an affected VIN list from their Zone Office when owner
notification begins. Vehicles will be assigned to retailers in the affected VIN list as follows:
•
Original vehicle owners are assigned to the original selling retailer when their current
address is within a 100 mile radius of that retailer.
•
If the original selling retailer is inactive, the VIN has been assigned to the nearest
active retailer.
•
For any new owners or when original owners live more than 100 miles from the
original selling retailer, the VIN has been assigned to the nearest active retailer.
IMPORTANT: Retailer affected VIN lists include owner name and address information for
vehicles affected by this service program. This information will enable retailers to follow-up
with owners of potentially affected vehicles. The lists contain owners’ names and addresses
obtained from State Motor Vehicle Registration Records. The use of such motor vehicle
registration data for any other purpose is unlawful. Accordingly, retailers are required to limit
the use of these lists for the purpose of completion of this Service Program.
SUBARU RETAILER PROGRAM RESPONSIBILITY
Retailers are to promptly perform the applicable service procedures to correct all affected
vehicles in their inventory. Additionally, whenever a vehicle subject to this service program
is taken into inventory or in for service, necessary steps should be taken to ensure the Service
Program has been performed before selling or releasing the vehicle.
Any vehicles listed in a Service Program that are in the retailer’s stock must be:
•
Immediately identified
•
Tagged or otherwise marked to prevent their delivery or use prior to inspection and/or
repair
•

MODIFIED VEHICLES
Aftermarket Engine Control Module (ECM) software changes may adversely affect the proper
operation of some vehicles and prevent Subaru retailers from performing the ECM software
logic update described in the WQW-58 customer letter. If unable to perform this update as
a result of non-authorized modifications made to the vehicle’s ECM, the vehicle must be
returned to its original factory condition at the Owner’s expense. In this case, the Owner must
be informed of their options to return the ECM to original condition by one of the following
methods:
•
•
•
•
•
Owner removes non-authorized ECM modifications returning ECM to original
condition
Owner installs the original ECM
Owner requests retailer install the original ECM (at vehicle Owner’s expense)
Owner installs a new factory ECM
Owner requests retailer install a new factory ECM (at vehicle Owner’s expense).
If aftermarket engine modifications are preventing completion of the engine inspection or
repair procedures outlined in this service campaign, the customer must be informed of their
options to:
•
•
Owner removes the aftermarket engine modifications
Owner requests the retailer remove the aftermarket modifications (at vehicle 		
owner expense).
If any of the following conditions exist, the retailer must complete the Vehicle Modification
and Accident Damage Form as found on Subarunet under Service/Forms.
•
		
•
		
•
		
		
Owner declines to return the ECM to original factory condition, ECM
modifications are preventing installation of required software update.
Owner declines to remove the aftermarket engine modifications, Engine
modifications are preventing completion of the engine testing or repair.
Retailer determines the procedure cannot be performed with existing
modifications. Engine or ECM modifications are preventing the retailer from
completing some portion of the campaign procedures.
All completed Vehicle Modification and Accident Damage Forms must be forwarded to
[email protected]. A list of modifications and photos must be included. These forms
will be used to document the condition(s) preventing the completion of this campaign and will
be noted on the Coverage Inquiry Report located on subarunet.com/Service-Claims Entry/
Info/Vehicle Inquiry (combined).
In addition, the following language must be noted on the Repair Order:
“Aftermarket Engine Control Module (ECM) software changes and/or aftermarket engine
modifications are preventing completion of the service campaign described in the WQW-58
customer notification letter. Your Subaru retailer is unable to perform this update as a result of
non-authorized modifications made to your vehicle’s ECM or engine. Subaru will not be able
to assist you until your vehicle is returned to its original factory condition. If this software
update is not performed or if the installed aftermarket modifications cause similar engine
damage as addressed in this Service Program, Subaru may not assist with any resulting repairs
to the vehicle.”

Follow the procedure steps below when a potentially affected vehicle presents for repair.
Perform a Vehicle Inquiry before proceeding to Step 1.
Step 1: Is WQW-58 open?
YES: Check the current CID of the ECM using SSM4. Refer to the above Pack File
Applicability table and proceed to Step 2.
VERY IMPORTANT: Regardless of whether the CID check shows the ECM is or is
not suitable for reprogramming (latest version already installed), this ENTIRE Service
Procedure MUST be performed on any vehicle subject to this Service Campaign. Record the
CURRENT (if ECM already has the latest logic installed) or the NEW (after reprogramming)
CID on the repair order hard copy as it is required for claim submission.
NOTE: If the ECM has been modified, refer to the Modified Vehicles section of this bulletin
before proceeding further.
NO: STOP. Do not proceed any further with this procedure. Diagnose any
Customer concerns following normal troubleshooting procedures using the applicable
Service Manual.
Step 2: Are there any DTCs (other than misfire related DTCs) stored in memory?
YES: Diagnose and repair as per the stored DTC(s) using the applicable Service
Manual. When completed, proceed to Step 3.
NO: Proceed to Step 3.
Step 3: Reprogram the ECM following the currently established normal procedure. When 		
complete, verify the “after” CID to comfirm successful reprogramming and record it
on the repair order hard copy.
Step 4: Remove and inspect the spark plugs closely for any damage, erosion or melting.
Inspect, rotate, turn upside-down and shake each spark plug to check for a cracked or 		
loose porcelain insulator around the center electrode. Take note which cylinder(s)
have spark plugs with verified damage and mark each plug, damaged or not, with the
corresponding cylinder number.
Continued...
Bulletin Number: WQW-58R; Revised: October 7, 2016
Page 5
NOTE: Any damage to the spark plug porcelain outside of the cylinder head is not a result of
this condition.
Step 5: Perform a cylinder leak-down test on ALL 4 cylinders following the procedures 		
supplied with the testing equipment being used. Record test results on the Repair
Order hard copy. Due to differences in leak-down test equipment, an actual cylinder
leakage specification cannot be provided. However, your results should be consistent
from cylinder to cylinder. Large variations in cylinder leakage readings will direct
you toward a problem cylinder. Experience with the test equipment being used and
past engine failure diagnosis should be your guides for how much variation between
cylinders is acceptable when damage has occurred to one or more cylinders. Contact 		
your FSE or Techline to review if you are uncertain about your test results.
NOTE: More information regarding cylinder leak-down testing can be found on STIS in
Technician’s Reference Booklet: Engine Theory and Diagnosis (MSA5P2106C).
Evaluation of Test Results
•
If the inspections performed in Step 4 above revealed spark plug damage, the engine
assembly must be replaced (refer to Part 3 of Flow Chart) following the procedure in
the applicable Service Manual.
•
If no spark plug damage is found but high or inconsistent leak-down results are
determined, reinstall the plugs and proceed to Step 6.
•
If the testing performed in Step 5 above revealed high cylinder leak down
percentages as described in the test equipment instructions or inconsistencies between
cylinders, use the table below as a guide to help determine where the compressed
air is being lost. If it is determined the compressed air is leaking into the exhaust, or
intake (heard escaping from the tail pipe or, throttle body), this would likely indicate
a valve sealing concern. Proceed to Step 6. If it is determined the compressed air is
leaking into the crankcase (heard escaping from the oil fill pipe and/or dipstick tube),
proceed to Step 6.
Step 6: Perform a top engine clean using SOA868V9160 Top Engine Cleaner and companion
tool #SOA868V9430. When completed, road test the vehicle then perform Step 5 		
again and re-evaluate the results. If the results are now consistent between cylinders,
the leakage was not a result of any mechanical concern. Reinstall the spark plugs to
complete the procedure. If there is still significant or unusual leakage past the intake
and/or exhaust valves, it is not related to this campaign. Diagnose and repair the
engine following the procedures in the applicable Service Manual. If there
is still significant or unusual leakage into the crankcase, proceed with replacing the
engine assembly (refer to Part 3 of Flow Chart).
Source of Compressed Air Loss:
Probable Cause:
Throttle Body
Intake Valve(s) Sealing *
Exhaust (Tail Pipe)
Exhaust Valve(s) Sealing *
Crankcase (Oil Fill / Dipstick Tube)
Piston Ring Sealing / Possible Ring Land(s) Damage
*This finding is not related to the condition(s) addressed by this bulletin. Engine replacement is not required.
When diagnosis and/or leak-down testing has confirmed either spark plug damage and/
or cylinder leakage into the crankcase, install a complete engine assembly (if available)
following the procedure in the applicable Service Manual (refer to Part 3 of the Flow Chart).
If a complete engine assembly is not available (and will be on backorder for 7 days or more),
a new short block assembly must be used for the repair along with replacing the affected
cylinder head (or heads) as required and described below.
Continued...
Bulletin Number: WQW-58R; Revised: October 7, 2016
Page 6
Replacement Cylinder Heads
If diagnosis and/or leak-down testing has confirmed either spark plug damage and/or cylinder
leakage into the crankcase, a complete “loaded” cylinder head assembly should be installed
for the corresponding “side” of the engine identified as having damage along with the new
short block assembly. EXAMPLE: If spark plug damage and/or leakage into the crankcase
has identified an issue in cylinder #3, the 1-3 (right side) cylinder head must also be replaced
along with the new short block assembly. Always review with your Parts Department and the
applicable Service Manual to determine any other components which may be required.
If a complete “loaded” cylinder head assembly is not available, the replacement cylinder head
must be “built” using a new “bare” head (bare heads include new valve guides) following the
procedure in the applicable Service Manual. The valve train components are to be changed
over from the original head assembly EXCEPT for the intake and exhaust valves from any
affected cylinder(s) which must be replaced. The remaining valve train components (spring
seats, valve springs, retainers and locks) along with the remaining miscellaneous components
are all to be reused. A “bare” head will also require installation of new valve stem oil seals
during reassembly. Always review with your Parts Department and the applicable Service
Manual to determine any other components which may be required.
Because some engine assemblies are no longer in active production or available, the following
substitutions must be used to complete those repairs if available.
REMINDER: Engine assembly replacement will only be required in a very limited number
of cases.
•
For 2014-15 Forester XT- order the 2017MY Forester XT Engine assembly p.n.

**NOTE: Additional parts will be needed when performing these repairs. These Parts Lists
are provided as reference only and may not be totally complete depending on the needs of
your specific repair. It is important to anticipate these needs and have all the parts needed to
perform the repair on hand to expedite the repair and minimize down-time.
NOTE: After uncrating the new engine assembly, always inspect it CLOSELY for any
damage which may have occurred during shipment.
Additional Tips:
•
When installing the new engine harness assembly:
o Use caution when removing the foam insulators from the high-pressure
fuel piping.
o The EGR assembly does not have to be removed as the new harness can
CAREFULLY be fed under the large EGR pipe as shown in the photos below.
•
After removing the “old” timing chain guide and sprockets, mark them accordingly so
they do not get confused with the new replacement parts.
•
Always confirm the reluctor between the flex plate and crankshaft flange on the new
engine matches the original BEFORE reinstalling the assembly.
•
Confirm the new engine assembly has both alignment dowels installed (and none in the
transmission).
Step 7: When the required repairs are complete, confirm the running condition of the engine.
If the engine runs normally, no further action is required. Affix the campaign sticker to the
radiator support and release the vehicle.

VERY IMPORTANT: If the engine continues to exhibit any idle roughness after completing
the testing and this ECM reprogramming, confirm your work to ensure the ignition coils and
spark plugs are correctly installed and undamaged. If any concerns are found, correct as
needed then check the engine’s running condition again. If any concerns persist, collect and
save an SSM IV data file showing the condition. While recording, be sure to mark the data
whenever any roughness occurs. Share the data file with the SOA Technical Helpline through
the SDS notebook. Include any FFD should a DTC set during these checks. Follow up with
the SOA Technical Helpline to review the saved data before proceeding further.
NOTES:
SOA now highly recommends connecting the Midtronics GR8 Diagnostic Battery Charger to
the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is
being reprogrammed. Once the GR8 is connected to the vehicle, as long as the battery is fully
charged, it takes less than 3 minutes to boot-up the charger, select the Power Supply Mode,
and have the battery voltage stabilized and ready for reprogramming.VERY IMPORTANT:
This information is applicable to the Midtronics GR8 Diagnostic Battery Charger ONLY. It
does not apply to any other brand / type of “generic” battery charger whatsoever. ONLY the
GR8 and its Power Supply Mode feature has been tested and approved by Subaru of America,
Inc. (SOA).
•
If the GR8 indicates the vehicle’s battery must be charged, charge the battery using
the GR8 before proceeding to reprogram the vehicle while using the Power Supply
Mode.
•
Control module failures as a result of battery discharge during reprogramming are
not a matter for warranty. Should any DTCs reset after the reprogramming update is
performed, diagnose per the procedure outlined in the applicable Service Manual.
NOTE: The pack file listings provided in this bulletin are the latest available at the time of
publishing. Updates are often released thereafter without revision to the original bulletin.
For this reason, it is critical to always have the latest version of SSM4 software installed on
your system. You can confirm if a later version is available by entering the CID listed in this
bulletin into FlashWrite. If a newer CID is shown as available in FlashWrite, reprogram using
that file.
STATE EMISSION TESTING ADVISORY
After ECM reprogramming, the OBD system’s readiness code monitors will reset to
“incomplete”. Normally, the vehicle needs to be driven under a variety of conditions before
the readiness code monitors will indicate “complete”. (See State I/M Program Advisory
Bulletin number 11-120-12R, dated 2-02-2016 for details.)
SERVICE PROGRAM IDENTIFICATION LABEL
Type or print the necessary information on a Service Program identification label. The
completed label should be attached to the vehicle’s upper radiator support.
Additional labels are available through normal parts ordering channels. The part number is
MSA6P1302. Ordering qty 1 = 1 sheet of 20 labels.

OWNER NOTIFICATION LETTER
Subaru Service Program WQW-58
February 2016
Dear Subaru Owner:
We would like to thank you for your selection of a Subaru vehicle. We take pride in our products and are
committed to your continued satisfaction.
Subaru has developed a modification to the Engine Control Module (ECM) software logic due to a possible
pre-ignition issue on certain 2015 model year WRX vehicles and certain 2014 and 2015 model year 2.0XT
Forester vehicles, equipped with a 2.0 liter turbocharged engine.
You received this notice because our records indicate that you currently own one of these vehicles.
DESCRIPTION
Under certain high engine load driving conditions, engine combustion may occur prior to spark ignition
resulting in elevated cylinder temperatures and pressures. This could cause a rough idle and engine noise, and
if left unaddressed it could lead to excessive erosion of the spark plugs and possible engine damage.
REPAIR
The repair will be performed at no cost to you. Subaru will inspect your vehicle and reprogram the ECM. If any
related spark plug or engine damage is detected during the inspection, your vehicle will be repaired.
WHAT YOU SHOULD DO
You should immediately contact your Subaru retailer (dealer) for an appointment to have this repair performed.
HOW LONG WILL THE REPAIR TAKE?
The time to perform the inspection and reprogramming is approximately three hours. However, it may be
necessary to leave your vehicle for a longer period of time on the day of your scheduled appointment to allow
your Subaru retailer flexibility in scheduling, or for repair.
CALIFORNIA REGISTERED OWNERS
The California Air Resources Board requires that emission related campaigns be completed prior to California’s
vehicle registration renewal process; without this repair, you will not be able to register your vehicle during your
next annual registration. Upon completion of this campaign, your California dealer will complete and provide
you a “Proof of Correction Certificate.” If required, present the certificate to the California Department of Motor
Vehicles (the “DMV”) when renewing your California registration as proof of campaign completion. If the DMV
does not request the certificate, we recommend that you keep it for your records.
In addition, the State of California requires that every vehicle must pass an emission test (SMOG Check) every two
years and before it is sold. Without the service we are providing at no charge, your vehicle may not pass this test.
