2008 MITSUBISHI LANCER EVOLUTION Power Train Problems

AYC PUMP FAILURE AT 44 THOUSAND MILES.

ACD/ AYC PUMP FAILURE, ONE TIME I WAS DOING FLUID INSPECTION ON MY CAR WHEN I NOTICE THE CARS ATF FLUID RESERVOIR IN THE TRUNK IS LOSING OIL. LOOKED AT THE FLOOR FOUND SOME RED OIL DRIPPING. IT MAY HAVE SEEM THAT PUMP MAY HAVE BEEN FAILING TO HOLD PRESSURE AND LOSE OIL. POSSIBLE GASKET FAILURE OR PUMP CRACK. BEEN SEARCHING ONLINE FOR SIMILAR PROBLEMS, I FOUND OUT IT SEEMED TO BE MOSTLY EVERY OWNERS PROBLEM. IS THIS SUPPOSE TO BE COVERED BY MANUFACTURER? SEEM LIKE POOR MATERIAL BUILD. *TR

VEHICLE WAS IN COLD WEATHER, AYC SYSTEM LIGHT TURNED ON. I CHECKED THE FORUMS AND FOUND THAT THIS IS A COMMON ISSUE THAT INDICATES THE PUMP IS BAD. THIS IS A VERY COMMON PROBLEM. *TR

IT WAS A COLD WINTER DAY, I STARTED DRIVING MY EVO TO A NEARBY GROCERY STORE. ENROUTE, THE AWD SYSTEM WOULD THROW A WARNING AND A DASHBOARD LIGHT LIT UP. I WAS CONCERNED, STOPPED THE VEHICLE AND FOUND NO LEAKS OR NO WEIRD NOISES. THE VEHICLE WAS UNABLE TO SHIFT INTO SNOW/TARMAC/GRAVEL MODE. FORTUNATELY I WAS NOT STRANDED ON THE ROAD SIDE. UPON FURTHER INVESTIGATION I CAME TO KNOW THAT THE ACD PUMP FAILED AND HENCE IT THREW AN AWD ERROR. ITS COSTING ABOUT 2200 DOLLARS TO FIX THIS ISSUE. *TR

WHEN STARTING MY 2008 MITSUBISHI LANCER EVOLUTION GSR, I RECEIVED A WARNING MESSAGE ON THE CLUSTER DISPLAY SHOWING A YELLOW-ORANGE SYMBOL THAT SHOWS 4 WHEELS CONNECTED BY AXLES AND THE MIDDLE-SHAFT, WHERE THE FRONT TWO WHEELS ARE FACING AT AN ANGLE TO THE SIDE. THE ERROR CODE READ AS C161E: DTC C161E: ELECTRIC PUMP RELAY CIRCUIT SYSTEM (STUCK). THIS HAS BECOME A VERY COMMON ISSUE WITH THE 2008 MITSUBISHI LANCER EVOLUTION. SO COMMON THAT WHEN YOU SEARCH FOR THE CODE C161E, YOU CAN FIND COUNTLESS FORUM DISCUSSIONS ON MULTIPLE WEBSITES COMMENTING ON THE FREQUENCY OF THIS ISSUE. INCLUDING MYSELF, A SINGLE DISCUSSION IDENTIFIES AT LEAST 48 UNIQUE CARS, 42 OF WHICH ARE THE 2008 MODEL YEAR, WHERE THE ACD PUMP FAILED, ALL OF WHICH HAVING DRIVEN FEWER THAN 75,000 MILES AND NEARLY 60% WITH LESS THAN 50,000 MILES (HTTP://WWW.EVOXFORUMS.COM/FORUMS/SHOWTHREAD.PHP?T=58221&HIGHLIGHT=C161E&PAGE=1). SEVERAL OF THESE VEHICLES REQUIRED MULTIPLE REPLACEMENTS OF THE SAME PART....

ACTIVE YAW CONTROL (AYC) AND ACTIVE CENTER DIFFERENTIAL (ACD) PUMP FAILED. NOT COVERED UNDER POWER TRAIN WARRANTY PUMP WAS CORRODED AND COULD NO LONGER PRODUCE ENOUGH PRESSURE. PUMP IN LOCATED DIRECTLY BEHIND PASSENGER REAR WHEEL EXPOSED TO WATER, SALT, AND OTHER ROAD DEBRIS. *TR

WENT TO DEALER FOR TRANSMISSION CHECK AND AFTER A MILE AWC LIGHT CAME ON THEY SAID IT HAD NOTHING TO DO WITH COMPUTER UPDATE THEY DID.MIND YOU MY TRANNY WAS GOING BAD AND DEALER DID NOT WANT NOTHING TO DO WITH IT EVEN UNDER WARRANTY. *TR

ELECTRONIC STABILITY CONTROL / S-AWC (TARMAC/GRAVEL/SNOW) INOPERABLE. TERRAIN SELECTION CAN BE PERFORMED AT 0MPH HOWEVER WHEN THE CAR IS PLACED IN MOTION: FORWARD / REVERSE, THE INSTRUMENT PANEL INDICATES THERE IS SERVICE REQUIRED IN THE AWD TRACTION CONTROL SYSTEM. THIS IS APPARENTLY A COMMON PROBLEM, FROM THE MULTITUDE OF COMPLAINTS FOR THIS SPECIFIC ISSUE POSTED HERE. *TR

ACD (ACTIVE CENTER DIFFERENTIAL) PUMP HAS FAILED AND WITHOUT THIS PUMP PROVIDING PRESSURE TO THE ALL WHEEL DRIVE SYSTEM, THE VEHICLE GETS STUCK ON DRIVEWAYS AT A STOP WHERE THE TIRE AND WHEEL PACKAGES ARE ON DIFFERENT ELEVATED SURFACES. THE REASON THE PUMP HAS FAILED IS DUE TO PLACEMENT OF THE PUMP ON THE VEHICLE. MITSUBISHI HAS DESIGNED THE VEHICLE TO HAVE THE PUMP TO BE LOCATED DIRECTLY BEHIND THE REAR PASSENGER WHEEL. DUE TO THIS, WHILE DRIVING ON SEVERE WEATHER ROADS (PARTICULARLY SNOW SALTED ROADS), THE DIRT, WATER AND SALT GETS KICKED UP TO THE POSITION OF THE PUMP WHICH CORRODES THE FITTINGS AND THE PUMP ITSELF. THIS THEN CAUSES THE PUMP TO FAIL OVER TIME. IT COULD HAVE BEEN EASILY REMEDIED BY RELOCATING THE PUMP OR ANTI-CORROSION PROTECTION AND BETTER SEALING. BEING LOCATED IN SOUTHERN CALIFORNIA, I WOULD HAVE THOUGHT THAT THIS WOULD HAVE NEVER HAPPENED TO ME,...

AS MANY EVOLUTION OWNERS WHO LIVE IN THE MIDWEST CAN ALSO ATTEST, MY EXAMPLE NOW JOINS THE CLUB OF MODELS WITH DEFECTIVE ASC/AYC PUMP FAILURE. THE PUMP FAILS WHEN OUTSIDE TEMPERATURES RUN CLOSE TO FREEZING, ON TOP OF THE UNIT CORRODING, AND EVOLUTION OWNERS ARE BEING FORCED TO SHELL OUT $1800 MINIMUM TO MITSUBISHI FOR THE PUMP ALONE, NOT INCLUDING LABOR. I BELIEVE THIS HAS ONLY OCCURRED TO MY MITSUBISHI AFTER SIX YEARS BECAUSE I'VE BEEN VERY GOOD ABOUT KEEPING THE UNDERBODY CLEAN, AND IT'S NEARLY ALWAYS PARKED IN A HEATED GARAGE. WITHOUT THE PROPER FUNCTIONING OF THIS INTEGRAL DRIVETRAIN EQUIPMENT, WE AREN'T ABLE TO CONTROL POWER DELIVERY FRONT TO BACK AND THE VEHICLE COMPUTER GOES INTO A TYPE OF LIMP MODE WHERE NO CONTROL OF THE DELIVERY OF POWER TO THE WHEELS IS POSSIBLE. OF COURSE THE BRAKES WORK AND THE THROTTLE WORKS, BUT WHEREAS THE VEHICLE USED TO...

CAR SYSTEMS ACD PUMP SYSTEM HAS FAILED. *TR

VERY COLD DAY OUT, ABOUT -15 F, WARMED UP MY VEHICLE FOR ABOUT 5 MINUTES PLUS. ONCE I BEGAN DRIVING, ABOUT 10 MPH MY SERVICE REQUIRED LIGHT CAME ON FOR MY AYC PUMP. DEALER SAID THAT IS WAS NOT COVERED UNDER WARRANTY OF ANY KIND. MITSUBISHI HAS KNOWN THAT IS A COMMON ISSUE IN COLD CLIMATES THAT USE SALT ON THE ROADS. THE SALT CORRODES THE PUMP AND MAKES IT FAULTY/MALFUNCTION. THIS IS A SAFETY ITEM THAT NEEDS TO BE RECALLED DUE TO THE KNOWLEDGE THAT AN EVO DRIVER HANDLES THEIR CAR [THAT THEY PURCHASED AS SUCH] AND LOOSES THAT RIGHT WITH A FAULTY AYC PUMP. *TR

I STARTED MY CAR AND THE AWC SERVICE LIGHT CAME ON. IT WAS ABOUT 0 DEGREES OUT THAT DAY, WHICH IS A VERY UNUSUAL TEMPERATURE FOR S. INDIANA. WHEN I STARTED THE CAR IT SCREECHED FOR JUST A SECOND AND THEN POPPED UP THE CODE. I RESTARTED THE CAR, JUST AS THE MANUAL HAD SAID AND WHEN I RESTARTED IT THE LIGHT WAS STILL ON. I WAS ABLE TO GET THE CODE READ IT THREW A C161E CODE WHICH IS AN ACD/AYC PROBLEM. AFTER DOING A LOT OF RESEARCH I FOUND OUT ITS A COMMON PROBLEM AND ITS AN EXPENSIVE PROBLEM, ABOUT $2,000+. I CALLED THE DEALER AND WAS TOLD MY WARRANTY DOES NOT COVER THIS, IT IS NOT PART OF THE POWER TRAIN. *TR

I STARTED MY CAR AND THE AWC SERVICE LIGHT CAME ON. I CAME TO A CONTROLLED STOP, AND RESTARTED THE CAR PER THE INSTRUCTIONS IN THE VEHICLE MANUAL. UPON RESTART, THE SAME SERVICE LIGHT CAME ON. AFTER THE DEALER RAN A DIAGNOSTIC, IT WAS FOUND THAT THE HIGH PRESSURE PUMP FOR THE ACTIVE STABILITY CONTROL SYSTEM HAD FAILED. I WAS TOLD THAT THIS PART WAS NOT PART OF THE DRIVE TRAIN AND WOULD NOT BE COVERED UNDER WARRANTY. THE DAY THE PUMP FAILED IT WAS VERY COLD AND THERE WAS PACKED SNOW ON THE ROADWAYS. IF I WAS DRIVING AT HIGHER SPEEDS AND THIS PUMP HAD FAILED, I BELIEVE THE AUTOMOBILE WOULD NOT HAVE BEHAVED AS EXPECTED WITH THE AWC STABILITY ACTIVE. *TR

THIS IS REPORT OF A KNOWN FAILURE BY MITSUBISHI MOTOR CORP. AT 50,800 MILES ON 12/17/2013 MY CARS SUPER-ACTIVE CENTER DIFFERENTIAL (S-ACD) STARTED BLINKING AT ME. IT WOULD NOT ALLOW CHANGING OF THE SETTINGS ANYMORE FOR TARMAC/GRAVEL/SNOW. IMMEDIATELY THERE AFTER, THE DRIVER INFORMATION PANEL POPPED UP WITH A YELLOW "AWD SERVICE REQUIRED" INDICATOR. I BROUGHT MY CAR TO NASHUA, NH MITSUBISHI/HYUNDAI FOR DIAGNOSIS ON 12/19/2013. THERE THEY APPLIED TSB-SC11-002. THIS UNFORTUNATELY DID NOT RESOLVE THE ISSUE. I WAS THEN INFORMED THAT THE CAR REQUIRED A REPLACEMENT ACD PUMP AND WAS QUOTED $1,995 FOR THE REPAIR, WHICH CONFUSED ME DUE TO THE FACT THAT MY CAR WAS STILL UNDER MANUFACTURERS POWER TRAIN WARRANTY, AND A PUMP, THAT CONTROLS THE AWD SYSTEM OF A CAR, SEEMS TO BE POWER TRAIN RELATED, AT LEAST IN MY EYES. THE NORTH EAST REGIONAL REPRESENTATIVE WAS CONTACTED ON MY BEHALF BY THE DEALERSHIP TO REQUEST COVERAGE...

(COMPLAINT IS APPLICABLE ONLY TO GSR TRIM EQUIPPED WITH A 5MT TRANSMISSION) - DIFFICULTY SHIFTING FIRST TO SECOND GEAR, AND SECOND TO THIRD. GEARSHIFT IS NOTCHY AND HARD TO ENGAGE. CAUSES LONGER THAN DESIRABLE TIME-GAP IN POWER TO THE WHEELS, RESULTING IN LOSS OF SPEED DURING ACCELERATION PHASE FROM A STOP. - GEARSHIFT IS NOT SMOOTH IN GENERAL. KEYWORDS : NOTCHY, GRINDING. - IT IS A WIDELY REPORTED PROBLEM IN THIS PARTICULAR MODEL AS EVIDENT FROM OWNER SURVEYS ON A PROMINENT INTERNET FORUM (SEE HTTP://FORUMS.EVOLUTIONM.NET/EVO-X-ENGINE-TURBO-DRIVETRAIN/333385-OFFICIAL-EVO-X-NOTCHY-GRINDING-TRANSMISSION-THREAD.HTML). *TR

BECAUSE OF THE LOCATION (REAR WHEEL WELL) AND DESIGN OF MITSUBISHI'S ACTIVE CENTER DIFFERENTIAL PUMP, THEY ARE PRONE TO FAILURE. SEVERAL FACTORS AID IN THE GALVANIZED CORROSION OF THE PUMP'S INTERNAL PLATE, SOME OF WHICH INCLUDE TEMPERATURE FLUCTUATION AND WEATHER. VEHICLES THAT ARE IN SERVICE THROUGHOUT THE SNOW BELT STATES IN THE US AND WELL INTO CANADA SEEM TO BE THE MOST AFFECTED. MY VEHICLE WAS JUST OUTSIDE OF THE VEHICLE WARRANTY RANGE FOR TIME BUT VERY WELL INSIDE THE RANGE FOR MILEAGE. *TR

THIS VEHICLE IS EQUIPPED WITH AN ACTIVE CONTROL DIFFERENTIAL (ACD) WHICH IS ACTUATED BY THE ACD HYDRAULIC PUMP. THE ACD IS A PART OF THE VEHICLE'S ALL WHEEL DRIVE SYSTEM. AFTER GIVING THE ENGINE AN 8 MINUTE WARM UP ON IDLE, THE VEHICLE WAS BEING DRIVEN ON A 20F OF AMBIENT TEMPERATURE. THE VEHICLE WAS ON A STOP LIGHT, AND UPON GENTLY ACCELERATING THE CAR ON GREEN LIGHT A WARNING LIGHT CAME UP ON THE VEHICLE'S DASH BOARD. THE VEHICLE WAS BROUGHT TO THE NEAREST MITSUBISHI SERVICE SHOP 4 DAYS AFTER THE INCIDENT WITH THE WARNING LIGHT STILL ON THE VEHICLE'S DASH BOARD. AFTER SERVICE TECHNICIAN WORKED ON THE VEHICLE, THE SERVICE MANAGER SAID THAT THE ACD PUMP IS THE PROBLEM WHICH NEEDS TO BE REPLACED AND WILL COST $2100 OF PARTS AND LABOR. 8 MONTHS PRIOR TO THE INCIDENT, THE MITSUBISHI SERVICE SHOP RE-FLASHED MY VEHICLE'S ALL WHEEL DRIVE...

STARTED MY CAR 1N 30 DEGREE WEATHER AND LET IT IDLE FOR A COUPLE MINUTES PULLED OUT ON MY STREET WHERE I LIVE AND MY ACD/AYC QUIT WORKING I HAD A PICTURE OF ALL FOR WHEELS ON MY INFO CENTER WITH THE FRONT WHEEL ON AN ANGLE . TOOK IT TO THE DEALER AND THEY SAID MY ALL WHEEL DRIVE PUMP WAS BAD AND THAT SINCE MY CAR IS AN EVO IT WAS NOT COVERED.I PAID TO HAVE IT FIXED AND GOT MY CAR BACK AND MY TIMING CHAIN BROKE DEALER SAID IT WAS NOT COVERED ALSO SINCE IT WAS AN EVO 3500.00 IN 1 MONTH. *TR

THE S-AWC OR SUPER ALL WHEEL CONTROL SYSTEM ON THE MITSUBISHI LANCER EVOLUTION HELPS THE ALL WHEEL DRIVE TO ACTUALLY WORK. I HAD A SERVICE MESSAGE POP UP ON MY CAR WITH THE S-AWC SYSTEM BEING INDICATED. AFTER REVIEWING THE CAR'S MANUAL AND THE INTERNET TO HELP DIAGNOSE THE ISSUE OF WHY IT WAS CAUSING IT, I'M TOLD THERE IS AN EVER-INCREASING NUMBER OF VEHICLES WITH THIS S-AWC PUMP FAILURE EITHER IN SUPER COLD CONDITIONS OR VERY HOT CONDITIONS. THIS HAS THE POTENTIAL TO BE VERY DANGEROUS IF THE PUMP ENDS UP GOING OUT WHEN SOMEONE IS MAKING A TURN OR IS RELYING ON THE ALL-WHEEL DRIVE TO ACTUALLY WORK IN ADVERSE CONDITIONS. THE ONLY NOTABLE CHANGE IS A DIFFERENCE IN STEERING FEEL AND THE SERVICE MESSAGE POPPING UP AFTER SEVERAL MINUTES OF DRIVING, THOUGH DUE TO SAFETY REASONS, I AM TRYING NOT TO PUSH THE CAR TOO HARD UNTIL...

AWC PUMP STARTED TO FAIL. IT IS NOW COMPLETELY FAILED AND NOT WORKING. AFTER SOME RESEARCH DETERMINED THAT IT IS A COMMON PROBLEM ON THESE VEHICLES DUE TO NOT BEING SEALED PROPERLY AND CORROSION GETTING IN TO DAMAGE THE PUMP MOTOR. PART SHOULD BE RECALLED/REPLACED UNDER WARRANTY BUT THEY REFUSE TO DO SO. *TR

ON MONDAY 2013 APRIL 22 I [XXX] (OWNER OF VEHICLE) WAS GETTING OFF MY SHIFT AT APPROXIMATELY 0700 HOURS FROM BETHEL TWP PD; WHERE I WORK AS A PATROLMAN. THE TEMPERATURE WAS FAIRLY MILD 60-65F, I STARTED MY 2008 MITSUBISHI EVOLUTION 10 TO LET IT WARM UP LIKE I ALWAYS HAVE FOR APPROXIMATELY TEN MINUTES. I PUT MY EVO IN GEAR AND ON THE CENTER L.E.D. SCREEN I RECEIVED THE C161 MESSAGE WHICH INDICATES S-AWC FAILURE OR SUPER ALL WHEEL CONTROL. THIS EFFECTS EVERYTHING WITH THE CARS' SUSPENSION STABILITY, YAW CONTROL, AND THE "SMART BREAKING" FEATURE. FOR AN UN-EXPERIENCED DRIVER THIS COULD BE CATASTROPHIC. KNOWING THE IMPORTANCE OF THIS I WAS FORCED TO BRING THE CAR TO SPRINGFIELD MITSUBISHI IN SPRINGFIELD, PA. 1(484)574-8434. NOW I'M STUCK WITH A $2132.00 BILL AND THE CAR IS STILL IN THE LOT BECAUSE I DON'T HAVE THE $2132.00 TO "SHELL" OUT. I WENT TO...

A FEW MONTHS AFTER I PURCHASED MY USED EVO X WITH 30,000 MILES AND A 5 YR/ 60,000 MILE WARRANTY, I NOTICED A PUDDLE OF FLUID ACCUMULATING WHILE IT WAS PARKED IN THE REAR PASSENGER SIDE OF THE VEHICLE. I SOON DID RESEARCH TO DETERMINE WHERE IT WAS COMING FROM. I LEARNED MY AYC/ACD PUMP IS LEAKING, AFTER FURTHER INVESTIGATING IT TURNS OUT THIS PUMP IS NOTORIOUS FOR LEAKING AND FAILING. THE MITSUBISHI DEALER DENIED MY WARRANTY CLAIM AND I WAS NEVER GIVEN A REASON, EVEN AFTER ASKING WHY. I HAVE SINCE THEN CONTACTED A THIRD PARTY DISPUTE CENTER. THIS PUMPS THE NECESSARY FLUID TO THE FRONT AND REAR OF THE ALL WHEEL DRIVE ASSEMBLIES. IF THIS PUMP FAILS, IT WILL ULTIMATELY DESTROY THE ENTIRE DRIVE TRAIN/ ALL WHEEL DRIVE SYSTEM. RESULTING IN IT LOCKING UP, CAUSING THE DRIVER TO LOOSE CONTROL. AS FAR AS I KNOW, THE DRIVER OF...

SATURDAY MORNING I WARMED UP MY CAR FOR 5 MINUTES. STARTED TO DRIVE MY CAR FOR ABOUT 15 SECONDS, AWD SERVICE REQUIRED POPPED UP ON MY DISPLAY. I STOPPED THE CAR AND BROUGHT IT BACK HOME. LOOKED UP WHAT THE ISSUE COULD BE AND FOUND OUT THAT THE ACD PUMP HAS FAILED. THIS IS A WELL KNOWN PROBLEM FROM MITSUBISHI FOR THESE CARS AND THEY HAVE NOT ISSUED A RECALL OR REAL FIX. WITHOUT THE ACD PUMP FUNCTIONING, THERE IS A POSSIBILITY THAT THE CAR CAN LOSE TRACTION IN CERTAIN SITUATIONS OR DAMAGE THE ENTIRE DRIVETRAIN SYSTEM. MITSUBISHI CLAIMS THAT ITS NOT PART OF THE DRIVETRAIN SO THERE IS NO WARRANTY AND IT'S ALSO A "LUXURY" SYSTEM. CONTROLLING WHEEL TRACTION IS NOT A LUXURY ITS A SAFETY FEATURE. *TR

I HAVE A 2008 LANCER EVOLUTION. THE SERVICE REQUIRED LIGHT FOR THE ALL WHEEL DRIVE SYSTEM CAME ON. I ONLY HAD AROUND 59000 MILES ON THE CAR WHEN THIS HAPPEN. I TOOK IT TO THE DEALERSHIP AND THEY SAID IT WAS AN INTERNAL FAULT IN THE AWC PUMP. THEY SAID IT WOULD COST $2250 PLUS TAX TO REPLACE. SO I CALLED MITSUBISHI TO SEE IF THEY WOULD REPLACE THE PUMP FOR FREE SINCE IT IS A SAFETY CONCERN. THEY SAID NO SINCE MY 3 YEAR OR 36000 MILE WARRANTY WAS UP. A LOT OF EVOLUTIONS IN COLDER CLIMATES HAVE BEEN HAVING THIS SAME PROBLEM. THE COLD WEATHER MAKES THE FLUID IN THE AWC PUMP TO THICK AND IT CAUSES IT TO BURN UP. WITHOUT THE PUMP WORKING THE ALL WHEEL DRIVE SYSTEM IS NOT FUNCTIONING RIGHT AND MAY CAUSE A WRECK IF IT LOCKS UP. MITSUBISHI EVEN RELEASED AN AWC...

MITSUBISHI MOTORS OF AMERICA HAS A AWD ECU SOFTWARE UPDATE FOR VEHICLES SPECIFICALLY DRIVEN IN COLD CONDITIONS. DEALERSHIPS AND MITSUBISHI CORPORATE HAVE DENIED MY CLAIM TO OBTAIN THIS SOFTWARE BECAUSE MY CAR WAS SOLD IN CALIFORNIA AND THEY HAVE SAID IT IS NOT ELIGIBLE. I TAKE MY VEHICLE EVERY YEAR UP IN THE SIERRA NEVADA MOUNTAIN RANGE WHERE TEMPERATURE CONDITIONS ARE SIMILAR TO ANY OF THE NORTHERN STATES WITHIN THE SERVICE BULLETIN. THE MITSUBISHI SERVICE BULLETIN NUMBER IS SC-09-002 ALSO AVAILABLE HERE ON GOOGLE DOCS TO READ ( HTTP://DOCS.GOOGLE.COM/FILEVIEW?ID=0BZNIGP9LGBK8NTU5OTRINJGTZTJHMC00MJY0LWI2NMMTOWZHZJU1NZFKNDCZ&HL=EN) IT STATES THAT "THIS REPROGRAMMING PROCEDURE WILL MODIFY THE ALL-WHEEL-CONTROL (AWC) ECU SOFTWARE TO ACCURATELY MATCH THE OPERATIONS CHECK OF THE AYC/ACD MOTOR WITH CURRENT AMBIENT CONDITIONS. EXTREMELY COLD WEATHER CAUSES INCREASED EXCESSIVE LOAD ON THE MOTOR, WHICH COULD RESULT IN DAMAGE TO THE MOTOR. THIS BULLETIN DESCRIBES PROCEDURES TO REPROGRAM THE AWC ECU WITH NEW SOFTWARE PARAMETERS TO PREVENT THIS...
