Second on the high pressure fuel pump oil seal failure. Dealer said seal was installed by the factory incorrectly. Failure discovered during 10k service.

Please list VIN numbers for this engine failure so we can have something to research on our cars.
Thanks

Copied from another 3.6 engine failure thread originally posted by myself:
A customer had his 3.6 passat towed in because it was running rough and the engine light was flashing. Turns out the timing gear bolt backed out just enough to allow the gear to wobble and shear off 4 teeth. The tech replaced all timing gears, chains, tensioners, and hardware at the QTM's recommendation. So the tech replaces everything and takes it out for a test drive. After coming back from a 20 mile test drive, the the parks the car and notices a *little* smoke coming from under the hood. He pops the hood and the rear of the engine has just caught fire. Apparently the bolt backed out again, cut a hole in the timing cover and the gears and chain were flinging the oil (in a fine mist) right onto the left catalytic convertor.
Needless to say the engine was replaced with a new engine.
Ohh Yeah, Did I mention the car had only 4400 miles on it?
Here is the VIN and date of production of the vehicle that had the engine replaced at my dealership at 4400 miles
*****73C*7E042774
With a production date of 07/14/2006

Got car back transmission problems 2 days later, fixed (?) Sure for about two more days now back in shop for new transmission. (Details to follow)Don't really want to post vin #. Sister-in-laws car, but I'm the one that took into dealer each time. ( I have 2006 Jetta TDI, with that glorious DMF!)

'07 B6 3.6 wagon. roughly 16k miles
date of production: ?
*****93C*7E004997
Car was taken to dealer due to solid check engine light (which had appeared the previous day). Simultaneously, it developed a slight new "rushing" noise under acceleration. Finally got it back today.
The problem as described to me was that one of the bolts securing the oil pump sheared into two pieces, thus causing the oil pump to begin to tilt out of position. This affected the cam timing enough to throw the code (thank goodness). They basically replaced the oil pump and the entire cam drive train, including a new stronger bolt. Pulled head and oil pan to look for any sign of damage to the engine, none found.
I don't know how often this problem manifests with the cam position sensor code, but perhaps this should be a reinforcement to 3.6 owners to not delay if they see the light come on. I'm convinced that taking it in quickly avoided a full engine replacement in my case.

06 3.6
Taken to dealer with CEL, sputtering in accelartion most noticable at 2200 Rpm or right before it shifts into 3rd.
Dealer informed Itermediate sproket bolt sheared and had been sheared for a while. Sprockets floating loosley togther Replaced both chains, timing cover, further problem after repair oil pump failure.
Might be further problems, Dealer has not been forthcoming with full info found notation on repair sheet from Dealer with VW found aluminum shavings on Oil pump.
Going back in the dealer for itermediate high RPMS at idle, very hard shifting between 1 and second gear.

Re: ***OFFICIAL*** 3.6L 24V Engine Failure Thread (8606)

Came across this in another thread in the VWVortex Forums. Any possibility that the 3.6L engine failure is linked to the factory in which the car is assembled at?
I noticed that someone had posted a VIN. Checked it out and it says that the car was manufactured at the Emden, Germany factory. Are the others coming from the same factory?

Pasted the posting on VIN and determine factory.

I have had 2 different Touregs with the V6 engines. The first one I had bought in Feb. of this year and first road trip the engine blew up, coming back from Salt Lake City Utah. The dealer replaced the vehicle with another Toureg. Just Came Back from Yuma Arizona and lost power and engine light came steady on with 4500 miles on it. Took it to the dealer and they told me it had the same problem as the first one. The dealer told me it was the chain tensioner coming loose in the engine and there is about 600 engines or more out there with this problem.

Re: ***OFFICIAL*** 3.6L 24V Engine Failure Thread (volkwolf)

How widespread is this problem? I might be in the market soon for a new car and I was interested in the 3.6. I mkght have to wait to see how 2008's do or buy something else.

 

[kaesem]

Production date of Vehicle: 1/06
Failure (if noted by dealer): Did not say, but think timeing chain related. Just said that they were going to replace the engine.
10,308 miles

Oil Pressure Failure warning light came on.
Towed to dealer.

Re: ***OFFICIAL*** 3.6L 24V Engine Failure Thread (gugarci)

I wouldn't recommend buying a new VW with a 3.6L 24v Engine. This problem with the engines seems to be all over. I plan on trading my toureg in and getting something else. I have had problems with (2) of them, with the 3.6L motor in them. I also just found out a couple of weeks ago that the fuel pumps in the new 2.0 Turbo engines are vapor locking and causing the car to shut off if they get to hot.
So VW is not doing so well.
VIN for Touregs are WVGZE77L17D004543
WVGZE77L87D003602
