      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

      Performed gff and found multiple misfires on cylinder 2&3 checked and found low compression on cylinder 2&3. Removed engine and transmission per techline. Disassembled and found intermediate shaft bolt broken causing severe internal engine damage. Contacted vta & Steve ******. Ordered new engine. (Car in shop 15 days)
      Build date September 2006.
      Engine failure 8,804 miles
      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.

      Update for everyone, I will edit and post Vin tomorrow at work.

      CEL liht back on today had the car back less than a week. Sputtering and ticking loudly. temp sensor says good but engine smells extremely hot.

      Having it towed to dealer in the morning.

      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.

    18. 07-25-2007 08:23 AM #18
      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.

      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.

      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

      Update on my 3.6L engine replacement. VW replaced the engine in about a week. Final tests on the replacement engine claimed they heard " a funny noise" and VW of America wanted them to replace the engine again.

      Replaced the second engine, and now determined they needed to order another oil cooler. Will take another week.

      It has had enough days in the shop for the Lemon Law to be in effect.

      Update on the 2007 Toureg still in the shop since 7/2/07. Went to pick it up and they scratched the front end up and passenger side headlight. It's getting repainted on the front end, and the passenger side headlight is getting replaced.
      Called Corporate about the situation to get my down payment back from them. The told me to basicly screw off. VW SUCKS!!!!!! BIG TIME WHEN YOU HAVE PROBLEMS WITH THERE CARS.

      Are there any symptoms prior to the engine failing?

      My 3.6 4motion wagon has been making this metal rubbing/whining noise at 30-40mph and 75+ mph on hot days since about 2k miles (now it has 8k) Spent over 3 weeks with the dealer and they can't find anything wrong.

      They said they would get a VWoA rep out here to look at it but it has been nearly 3 months and I haven't gotten a call from them. Contacted VWoA and they said I would be contacted within a week, it's been over 1 month and still no call back.

      The main sympton is loss of power and the engine light comes on steady.
      It sounds like that your 3.6 4motion you have is having the failure with the engine. If it was me I would just take it out and run the hell out of it. Pulling hills and high rpms will put it to the test, just run it hard.
      Don't depend on VW to call you back they won't. I just got my Toureg back today and It is leaking tranny fluid now, so it's got to go back in the shop. Bottom line VW has produced Junk for the public market and is trying to get out of the mess as cheap as possible.

      To mine happened that i had to replace camshafts all gaskets dismount all engine dismount gearbox and replace oil pump and under the cylinder head replace a oil retention valve . all that after 5.000 miles

    28. 09-02-2007 07:58 PM #28
      The reason is a oil retention valve under the cylinder head you have to dismount al engine replace the gaskets oil pum and the valve all the reliability of engine is suporte by this oil valve close betwen engine and cylinder head.

      Update...........

      Just got off of the phone with my service advisor at the dealership. VWoA has agreed to replace my entire engine. Will take about a week to get the new engine shipped and installed.

      Perhaps I can finaly enjoy owning a B6 if all goes well with the new engine.

      What worries me the most is the idea of this happening............after warranty!!

    33. 09-15-2007 08:47 AM #33
      More than likely it will happen before warranty, even before 10k miles. Lemon Law is tricky (vague) on state website. Now we know specifics. Sister-in-laws car unable to use lemon law , but VW agreed to replace car (due to all the other problems). Hopefully the new car will be trouble free. Hey you have to be optimistic.

      Model: 2007 Passat Wagon 3.6L
      Production Date: Unsure, purchased in Jan 07

      See: http://forums.vwvortex.com/zerothread?id=3451148

      PM me if you have had this failure and I'll put together a folder of all the work-orders related to this problem. Maybe bringing this evidence to our dealerships will convince them to do a preventive fix.
