2006 Volkswagen Jetta Fuel System Diesel Vehicle Speed Control Engine Problems

THE VEHICLE HAS A LONG HISTORY OF THE THROTTLE BECOMING INOPERATIVE RESULTING IN NO-POWER (IDLE POWER STRICTLY SPEAKING) CONDITIONS. THAT CONDITION IS CLEARED WHEN THE CLUTCH PEDAL IS DEPRESSED AND RELEASED. RECENTLY THERE WAS AN INSTANCE OF UNCOMMANDED ACCELERATION: INSTEAD OF NO POWER, FULL POWER WAS APPLIED BY THE ENGINE. AGAIN CYCLING THE CLUTCH CLEARED THE CONDITION. THE NO-POWER CASES APPEARED MORE LIKELY IN URBAN DRIVING AND SOON AFTER A TRANSMISSION SHIFT BUT DID OCCUR UNDER ALMOST ANY CONDITIONS. THE FULL-POWER CASE OCCURRED ONCE, CLIMBING A HILL AT ~2800' ALTITUDE. THE POWER FAIL OCCURRED AS EARLY AS 34K MILES, AND CONTINUED WITH VW'S KNOWLEDGE UNTIL ~72K MILES, WHEN VW OF AMERICA TECHNICIANS FINALLY DID SOMETHING TO END IT. THOSE SYMPTOMS STARTED RECURRING AT ~270K MILES. THE ACCELERATION INCIDENT OCCURRED AT ABOUT 275K MILES. THE VEHICLE HAS BEEN TAKEN OUT OF SERVICE; IT WILL BE SENT TO A SALVAGE YARD IF THE NTSB IS NOT INTERESTED IN THE VEHICLE. *TR
