2006 Volkswagen Jetta

So it appears to be fine until about 30/45 mins drive time Then it starts shifting/slamming real hard and hesitates to shift in the next gear To the point where stopping and going isn’t an option or it slips After about 45 mins all the prnds lights turned on and did the same in manual mode.. I read someone it’s a valve body that leads to a faulty Tranny I’ve read almost 150 of the same exact accounts on here and Reddit With the same 2006 Vw Jetta 2.5 It’s too common of an issue Most of them were under 100k miles and never dealt with by the manufacturer Myself my car has roughly 168k miles and I’ve been working to fix it up I just got it a month or so ago And now I have to deal with this Honestly is sad that VW hasn’t been held accountable for an issue that is WAY TOO COMMON to not be their fault. I understand the car is almost 20 years old but a bunch of these accounts i were reading dated as far back as 2009 with 86k miles it’s a shame..

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

MY CAMSHAFT AND LIFTERS WENT BAD AND WERE REPLACED IN 2015. IT WAS JUST AROUND 100,000 MILES. THEN I FOUND OUT TODAY THAT THEY WERE BAD AGAIN. MY UNDERSTANDING FROM THE MECHANIC IS THAT THIS IS A COMMON PROBLEM, AND LOOKING AT THE VOLKSWAGEN TDI FORUM, THAT YEAR IS PARTICULARLY BAD. THIS CAMSHAFT FAILURE CAUSED A LOSS OF POWER ON THE INTERSTATE DURING A HEAVY TRAFFIC TIME, BOTH TIMES. FIRST INCIDENT WAS ON I-240 IN ASHEVILLE MIDDAY. SECOND TIME WAS TRAVELLING WEST ON I-40 NEAR MORGANTON, NC IN EVENING TRAFFIC. LOSS OF POWER, SMOKING. I COULD BARELY GET OFF THE EXIT. I WAS LUCKY NOT TO HAVE IMPEDED TRAFFIC, BOTH TIMES.

WHILE DRIVING ON THE INTERSTATE JULY OF 2015, GOING ABOUT 70 MPH, MY 2006 VW JETTA SHOOK AND LOST ALL POWER. NO CHECK ENGINE LIGHTS OR ANY LIGHTS AT THAT MATTER CAME ON. PRIOR TO THIS I WOULD NOTICE THAT TAKING OFF SOMETIMES THE TURBO WOULDNT KICK IN AND I WOULD HAVE ABSOLUTELY NO POWER WHILE GETTING UP TO SPEED. THIS ALSO HAPPENED ON THE FREEWAY AND ONCE OFF OF THE FREEWAY I TURNED THE CAR OFF AND THEN ON AND WAS LIKE NOTHING HAPPENED. AFTER I LOST ALL POWER THE SECOND INCIDENT, I TOOK IT INTO THE SHOP AND WAS TOLD THAT 2 CYLINDERS WERE COMPLETELY DESTROYED. HAD TO SPEND 2400 DOLLARS TO HAVE A NEW MOTOR PUT IN AND NOW THE THING IS HAVING PROBLEMS AGAIN. BATTERY LIGHT KEEPS COMING ON AND OFF WITHIN A SECOND AND THERE IS A LOUD TICKING NOISE WHILE IDLING. SOUNDS LIKE A LOUD VACUUM IN THE ENGINE COMPARTMENT WHILE DRIVING IT. NO CHECK ENGINE LIGHTS OR TEMPERATURE GAUGE INCREASES ARE PRESENT. WHILE RESEARCHING RECALLS I NOTICED THERE WERE SOME FOR THE YEAR OF MY JETTA SO WANTED TO SEE WHAT IS GOING ON.

I HAVE TWO MAJOR SAFTEY PROBLEMS THAT COULD HAVE ENDED IN A FATALITY.FIRST MY TRANSMISSION WENT OUT WITHOUT A WARNING WHILE I WAS ON THE INTERSTATE GOING 75 MPH AND A 18 WHEELER WAS BEHIND ME THE CAR DROPT DOWN TO 40 MPH AND I ALMOST GOT REARENDED BY THE SEMI.I HAD THE TRANSMISSION REBUILD.SECOND THING I PULLED OUT OF BURGERKING AND THE CAR HAS NO POWER AND ABOUT GOT TBONED AND THERES NO CHECK ENGINE LIGHT ON.

ORIGINALLY, THE TURBO WOULD LOSE BOOST AND THE ENGINE WOULD LOSE POWER. AFTER SOME TIME, PARTICULARLY DURING WET WEATHER, THE CAR WILL SUDDENLY VIBRATE, JOLT, AND THEN THE ENGINE WARNING CHIME SOUNDS. THE TACHOMETER DROPS TO ZERO, THE OIL PRESSURE LIGHT COMES ON, THE STABILITY CONTROL SHUTS OFF, THE GLOW PLUG LIGHTS FLASH, REAR WINDOW DEFROSTER WILL NOT WORK, CRUISE CONTROL WONT WORK, AND IF THE CAR IS SHUT OFF IT WILL NOT RESTART. THIS IS PARTICULARLY DANGEROUS DURING SNOW OR RAIN, AS THE CAR LOSES TRACTION CONTROL DURING WEATHER IN WHICH IT IS MOST IMPORTANT TO HAVE. ALSO, IF THE CAR DIES AND IS ON THE SHOULDER OF THE ROAD, DURING RAIN OR SNOW, THERE IS POOR VISIBILITY AND IT INCREASES THE RISK OF SOMEONE HITTING THE DISABLED CAR. I HAVE SEEN MANY MENTIONS OF THIS SAME EFFECT HAPPENING ON OTHER 2006 TDI MODELS, AND IT SEEMS TO BE A RECURRING ISSUE WITH THIS PARTICULAR MODEL AND ENGINE TYPE. THE ROOT CAUSE APPEARS TO BE AN ELECTRICAL HARNESS THAT RUNS IN THE ENGINE COMPARTMENT CHAFING OVER TIME, WHICH HAPPENS OUTSIDE OF THE WARRANTY PERIOD, BUT CAUSES SIGNIFICANT SAFETY CONCERNS WITH ITS FAILURE MODE.
