Wife was driving on interstate, experienced loss of power, engine still ran, drove home, could tell power was down........3 of the lifters had holes in top and cam was worn on some lobes at 92,000 miles. Researched and there was an issue with our model '06 Jetta TDI but VW said it ws our problem, not theirs. Was told by many that the cam was a bad design, had narrow lobes?, and did more than just move the lifters?.
You might want to have shop check out the lifters and cams. We found a shop that did cam and lifters and related for $2800. Waiting for recall, but not expecting any money back from VW.
I have photos of lifters and worn cam if interested.
The reason the cam lobes are so narrow in the MK5 is because they also have to operate the 4 fuel injectors as well as all the valves. The engine block is short and to make room for the extra 4 lobes they simply made them all narrower. This puts a lot of extra pounds per square inch pressure on the followers and they eventually beat their way through the tops of the cam followers...(but always out of warranty).
The 2006 VW Jetta TDI is an amazing car in many ways, but it is over engineered in places, and built like crap in others. VW knew the top end of the BRM engine was a problem and just dropped that whole design and marched on with the MK6 in the next re-do.
In fact the whole idea of the diesel engine economy is now a joke. The extra premium for the engine and the sky rocketing price of diesel makes the diesel vehicle ownership either a financial saw off or an outright losing proposition over the more fuel efficient gassers out there now.
Pardon me if I sound like a crank, but I think there is a conspiracy to get all the diesel car engines off the road by constantly increasing the emmissions standards and upping the price of the fuel well over that of gasoline.
(after all they can't force us to buy their Govt subsidised Ethenol in our TDI cars can they?)
Since it was replaced i have driven the car for over 3,000 highway miles and it has never faltered once, even tho I have tried to make it shudder by easing off on the downhill side of the run and then easing back on the engine as it starts to pull again going up the other side.
Nope, it won't do it anymore, so that is the end of that little story.

I went to a dealer and he explained that is how it is going to be as the car is 5 years old (a real jacka..).
Most probably fan control module 1 and 2 are not communicating well and thus
this problem.
If the cooling fan blows out due to this, the expenses are $900 for repair.
It makes way too much noise (compared to normal) and the dealer says it is NORMAL to have a sound
like this.
I guess the control fan module 1 and 2 // sensors are not communicating properly and needs to be
changed. Maybe the radiator fluid needs to be replaced.
Can someone guide me through this.
I am afraid that sooner or later the fans will burn out and I will have to shell out big bucks changing
the entire fan unit.
My 06' Mk 5 is still running fine (using Shell Rotella T6) and can't really find a good excuse to take a chance and trade it in for a new one.

These VW Jettas are designed to fail after 40000 miles in a way that
you will have electronic issues (big ones) as soon as you are out of your warranty.
They have a lot a electronic issues as well as mechanical issues with this model.
But they drive well if you are willing to take big hits every once in a while
Recall Date:
OCT 03, 2011
Model Affected:
2010 Volkswagen Jetta
Summary:
VOLKSWAGEN IS RECALLING CERTAIN MODEL 2009-2012 JETTA AND JETTA SPORTWAGEN VEHICLES, MANUFACTURED FROM MAY 2008 THROUGH SEPTEMBER 2011, MODEL YEAR 2010-2012 VOLKSWAGEN GOLF VEHICLES, MANUFACTURED FROM MAY 2009 THROUGH SEPTEMBER 2011, AND MODEL YEAR 2010-2012 AUDI A3 VEHICLES, MANUFACTURED FROM SEPTEMBER 2009 THROUGH SEPTEMBER 2011, THAT ARE EQUIPPED WITH A 2.0L TDI COMMON RAIL DIESEL ENGINE/CLEAN DIESEL ENGINE. THE FUEL INJECTION PULSES COULD COINCIDE WITH THE NATURAL FREQUENCY OF THE INJECTOR LINE #2, IN SPECIFIC LOAD AND RPM CONDITIONS. THIS RESONANCE CREATES ADDITIONAL STRESS IN THE FUEL LINE.
Consequences:
DUE TO THE RESONANCE CONDITION, INJECTOR LINE NUMBER 2 COULD DEVELOP SMALL CRACKS WHICH COULD LEAD TO FUEL LEAKAGE. LEAKING FUEL IN THE PRESENCE OF AN IGNITION SOURCE, MAY LEAD TO A FIRE.

What ever happened to fuel lines that lasted until the wheels fell off?
Very good post.
You point out several weaknesses in the Prius. Snow and ice practically leave them stranded. Unless they have added a switch to disable the electronic traction control I am sure it is still an issue. The Touareg has a switch to give you better control in snow and off road conditions.
I am still waiting for someone in a Prius to beat the records held by VW on 48 state trips. Our own Wayne Gerdes set the latest record. And he was a hard core Hybrid fan.
Volkswagen set a new Guinness World Record last week for lowest fuel consumption during an 8,122-mile tour of the lower 48 states in a Volkswagen Passat TDI Clean Diesel, achieving 77.99 mpg during the trip. This new record bested the previous one by about 10 mpg. During this record-setting trip the Passat TDI Clean Diesel also beat the hybrid record by more than 13 miles per gallon.
The 48-state trip took 14 days, with drivers Wayne Gerdes and Bob Winger purchasing only 104.94 gallons of Shell's ultra-low-sulfur diesel fuel for the duration of the trip. Gerdes is the founder of cleanmpg.com and is quite skilled in hypermiling techniques, which the driving team utilized throughout the trip.
And if you go to fueleconomy.gov and compare a prius to a vw tdi you'll see that the prius on average beats the VW tdi in the real world driving and not some hypermiling test.
So is my refrigerator. Does not make it all that enjoyable to be around. Yes the Prius is a decent appliance vehicle. Have I enjoyed the times I have ridden in them? NO, they are noisy rough riding little cars. Not in any way a pleasure to ride in or drive. Hey, but that is the beauty of America, so far. We can each drive what we like. I just got rid of a gas hog Toyota. So I am not in any way looking for another. At least it was a pleasure to get in and drive after running around town in my buddies Prius. The Prius I suggested he check out and he bought. He likes it fine. And he gets good mileage.
Unfortunately, the Passat has been given to a son and now has 150,000 miles and the Jetta last week had the entire fuel system destroyed. The car suddenly lost power as I was driving. I was told by VW dealer who did the repair, that the high pressure fuel pump was the cause of the failure and because diesel fuel lubricates the pump, most likely I had dirty or contaminated fuel. But they did not verify that the tank had been contaminated. I buy diesel at one location 95% of the time, and that location is noted on the VW website as a place to purchase fuel. So I have no answer to the question I asked the technician: How do I prevent this from happening again? I honestly don't know if I got a truthful story from them.
I'm interested in finding out if this has happened to other diesel car owners. I've lost my confidence in VW after owning VW's for 15 years.
The day before this happened I would have given the car an A+ for everything especially the 38-43 mpg I get.
What brand of diesel do you use 95% of the time. I have only used Chevron and Shell so far and get equal mileage from both.
It has been said many times before... always Always ALWAYS add your favorite diesel-fuel-conditioner when filling up.
Unlike additives for gasoline engines, a Diesel-fuel conditioner actually has measureable benefits:
*)LUBRICATION of the fuel-system
*) Increase Cetane of fuel (measurably increased MPG and quieter running engine)
*) in winter - eliminate gelling
Personally, I have always used DIESEL KLEEN® which is available at Walmart. (Grey bottle in summer and white bottle in winter)
At the risk of repeating common-knowledge... keep the bottle of additive in the trunk along with a supply of 8oz paper-cups. Just before filling up, grab a paper-cup and form a 'spout' on it. Pour approximately 6oz into paper cup and dump into fuel-filler before turning on the pump.
In this way, you can toss the used paper-cup in nearest trashcan and keep any odors out of your trunk.
