1999 VOLVO V70XC Engine And Engine Cooling Problems

FAILURE OF ELECTRONIC THROTTLE MODULE ASSEMBLY CAUSING VERY POOR DRIVABLE. PROBLEM IS INTERMITTENT AND SEVERE THAT THE CAR CAN NOT SAFELY BE DRIVEN IN TRAFFIC WITHOUT A RISK OF ACCIDENT. BRIEF CHRONOLOGY: I HAVE A VERY EARLY PRODUCTION 1999 VOLVO V70XC. IT HAD DRIVABLE PROBLEMS SINCE I BOUGHT IT. NEVER WAS FIXED. (SUPPOSEDLY) REPLACED ETM THE FIRST TIME IN ~ 2004, USING PART WHOSE DESIGN WAS KNOWN TO BE FAULTY. LATER DID SOFTWARE UPDATE (CAMPAIGN 155). DRIVABLE IMPROVED SLIGHTLY, BUT WAS NEVER CORRECT. REPLACEMENT MODULE IS NOW FAILING. CAR CAN NOT BE DRIVEN SAFELY. ENGINE RUNS POORLY, RPM LIMITED TO < 2000, ALWAYS IN "LIMP HOME MODE". YOU ARE AWARE (I BELIEVE) THAT THERE IS A RECALL/REPLACEMENT CAMPAIGN UNDERWAY FOR THIS PART. HOWEVER, THE REPLACEMENT PART HAS THE SAME DESIGN FLAW AS THE ORIGINAL. (I AM ALREADY ON A "SUPPOSEDLY" REPLACED MODULE). VOLVO IS PRETENDING TO HONOR AN EXTENDED WARRANTY...

DRIVING ON FREEWAY 65 MILES PER HOUR, VEHICLE LOSES COMPLETE POWER, ETS AND CHECK ENGINE LIGHTS COMES ON. I WAS ABLE TO COAST OFF THE FREEWAY ONTO THE RIGHT SHOULDER. TRIED SEVERAL RESTARTS TO SEE IF ENGINE WILL RUN NORMALLY, AFTER 10-15 MINUTES, STARTED CAR, ENG RAN NORMAL, ETS AND CEL LIGHT STILL ON. I WAS ABLE TO DRIVE HOME WITHOUT FURTHER INCIDENT. *TR

I BOUGHT THIS VOLVO USED W/ 120K MILES. I SAW RECORDS OF MAJOR WORK DONE AT THE DEALER JUST PREVIOUS TO 100,000 AND FIGURED IT WOULD BE GOOD FOR ANOTHER 100K. AT 131K, IT BEGAN CONSTANTLY STALLING AND LUNGING. I DID A TINY BIT OF RESEARCH AND LEARNED OF THE RECALL. I TOOK IT TO THE DEALER AND THEY TRIED TO CHARGE ME 200 TO DO NOTHING OTHER THAN READ THE CODES AND TELL ME THE ETM SOFTWARE HAD ALREADY BEEN UPDATED, AND THAT THE MASS AIRFLOW SENSOR WAS BAD. I REPLACED THE MAFS TO NO CHANGE. *TR

A SUDDEN DROP IN POWER ON FREEWAYS AND CITY STREETS. *JB
