Subaru Service Program WQC-39: Engine Control Module Reprogramming

Got the following email from Subaru today (it's also on MySubaru.com). Anyone else? I wonder if, when I take it in for this flash, they will also flash for the P0301-P0304 problem that many complain about ...
I'm also unhappy that unless I get my car flashed I the State of California won't let me register my car!


Dear Subaru Owner:

We would like to thank you for your selection of a Subaru vehicle. At Subaru, we take pride in our products and are committed to your continued satisfaction.

Subaru has developed a modification to the Engine Control Module software logic to improve the monitoring parameters within the On-Board Diagnostic (OBDll) system for the engine coolant thermostat. This correction ensures that should there be an abnormal condition (i.e., the engine coolant does not reach or maintain the proper operating temperature), the “check engine light” will illuminate. The proper illumination of the “check engine light” is needed to alert you that corrective action may be required.

This software change has no effect on fuel economy or vehicle performance.

WHAT WE ARE ASKING YOU TO DO PROMPTLY

We ask that you schedule an appointment with your Subaru Dealer as soon as possible to have your vehicle’s Engine Control Module software reprogrammed. This will take approximately 30 minutes to complete. However, it may be necessary for you to leave your car longer on the day of your appointment to allow your dealer flexibility in scheduling. Your Subaru dealer will perform this modification at no cost to you.

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.

Subaru thinks that Puerto Rico is part of the US but not part of Subaru USA.

And our local Subaru Dealer.... JA, not even have in stock OEM coolant. I just wandering what type of oil they use. Trebol Motors.... YOU SUCK big time!

I got the same email about my '11 Forester. Was wondering the same deal about the other error codes... Not in any particular hurry to get this done. With my next oil change, which isn't for another 5000 miles.

According to car facts this had already been done on my 2010 foz. It also shows up on mysubaru.com I reckon i'm good to go as that and the rear seat belt deal were the only recalls thus far and those have both been corrected.

I never received this email but the other night while driving our 2011 to dinner the Check Engine Light and Traction Control turned on and the Cruise Control light started flashing.

I took it in right after dinner and they performed the flash stating it might have been due to this reacall that all might dash lights were flashing. We don't have nearly as strict emmissions laws in Washington but I can say that it did fix the issue...for now.

Now to schedule an appointment for the seat belt recall. :)

Good. I'm taking mine in on Wednesday to get this flash. I don't have time for them to do the seatbelt thing.

I just got this done at the livermore subaru (california) with no problems. i have downpipe and exhaust.

I told them to NOT wash the car, do NOT change my air pressure in tires, do NOT do anything other than the ECM reflash. so he noted it on the paperwork for the tech.

uninstalled my AP in the parking lot before pulling up to service. got the reflash done and got the certificate. reinstalled AP in lot again before leaving.

going to send my updated rom to COBB and my tuner so they can update maps.

Had mine done a few weeks ago and have noticed no differences ... So far so good. They also did the ridiculous rear seat belt recall.
