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. …
The windshield wiper broke the window, brakes need replaced to soon, fuel system car has trouble fueling and after fueling and engine over heating due to engine cooling malfunction. None of these have been repaired yet it shows 0 unprepared recalls.
I purchased this 2006 vw Jetta tdi 1.9 turbo diesel new in 2006. After only 50K miles, vw dealership stated the turbo charger went bad and the warranty was initially refused stating it was improper oil used. This was disproved with receipts and still charged $500 of a $2300 bill. A few years later now in 2014,the vehicle was taken in for normal service and the next week, engine light came on. The same thing happened and vw states the turbo went bad and are generally only good for 50K miles. After sharing my anger about this, it fell upon def ears. I purchased another turbo out of california, due to not trusting vw any longer. This new turbo was installed and did not come with the wastegate module for it which is required for it to work. …
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. …
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. …
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. …
Camshaft failure due to excessive wear on a vehicle with 160,000 miles despite using vw recommended 505.01 specification oil and regular maintenance. Engine developed a rattling noise at highway speed, decreased performance, excessive black smoke coming out of tail pipe, and $1500 repair bill. Dual mass transmission flywheel failure on a vehicle with 120,000 miles resulted in rattling noise in the transmission, vibration of the whole vehicle and $1200 repair bill. Both of these issues are widespread. Multiple owners of this year/make/model have experienced these exact same issues due to poor quality parts originally installed by the manufacturer. Manufacturer should recall the affected vehicles and fix these issues due to them being widespread. There are numerous discussions on public forums of these issues as well.
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.
Tl* the contact owns a 2006 Volkswagen Jetta. While driving 30-40 MPH, there was a sudden loss of power. The dealer stated that the engine control unit failed and caused the vehicle to go into limp mode. As a result, the engine control unit shut off the fuel. The contact stated that this was a design by the manufacturer as a safety feature, and that the vehicle operated as intended. The vehicle was repaired; however, the contact was concerned that the failure was not addressed. The manufacturer was notified of the failure. The approximate failure mileage was 42,000. ...updated 04/12/16 updated 04/13/16.
