I found another person who had simular problems and it turned out to be that the tentioner that keeps the the cam chain tight lossened a little and it caused the cam chain to slip 1 tooth. I may pull the vlave cover tonight and see if mine done the same thing. Ill keep you posted.

I have kept my mouth shut till now, and Travis is being REALLY polite and restrained, so allow me to step up....

If I counted correctly, the post count of 22 that you show on our forum up to this point is confined to this one thread. A veteran VW technician, mechanic, whatever the hell you want to call me, with roughly 19 years of experience with them, allow me to say a couple of things....

First, sorry the local dealer couldn't in your mind help you. Doing this stuff for a living for so many years, I am painfully aware you can spend MANY HOURS trying to figure something out, and you keep coming up empty-handed. You are critical of them, but, for the record, if you were charged 3 hours, they probably spent 5 or 6 or more... They had the car for a week? Did they charge you for a week? NO. I have been that flat-rate tech, and the service manager tells you he can't pay you for all the time you spent trying to figure a problem car out. I assume you have a job? You go to work for 8 hours a day? You get paid for 8 hours? I have been at work 9 hours and paid for 2... that's the world a diagnostic tech lives in.... sorry you feel like you paid too much. You might want to give the dealer a call so you can find out who the tech was and offer to by dinner for his family, since he won't be able to pay for it.

Second, You say you think you can do better installing parts, and save money? That's a good one... seems to this on-looker like you would be even more angry if they had done that... Besides, a REAL TECHNICIAN doesn't just throw parts at a car... A doctor does more than put a band-aid on. Technicians that do have caused the negative image in the public's eye of mechanics.... so maybe that's not the best plan afterall.

Third, you have someone who will diagnose the problem for free? Great. Go for it. I don't know Sal, but hear great things about him. I won't diagnose ANYTHING for free... that's the hardest part of the job, putting on the part isn't a big deal... My employer needs to pay rent on the building, utilities, my paycheck... pretty sure you can't do that if you don't charge people for the work you do. I am good at what I do, yet don't live in the mindset that I am the greatest, but I am worth getting paid for doing my job.

Standing on the side lines and complaining about the game is a lot harder than getting on the field and playing. I hope you do finally figure it out. I wish you the best of luck... Veteran members of this forum have tried to offer you the advice of getting someone who knows what's up on one of these cars to help.... if they actually want to charge you for that help, sorry for that.

By the way... it's "tensioner", not "tentioner"....

Rick out....

THATS MY BOY !!!!!!!!!! Can we all say AMEN. I couldn't add anything more to that post if I had tried.

Im sorry if I have seemed unthankful. Thank you to everone for your help thus far. I didnt mean to piss people off. If I get it fixed Ill post what the problem was. Otherwise I keep my mouth shut.

Quite the contrary, you didn't "piss me off"... Very few people are actually able to get me in to that sort of state. I was just trying to make a few valid points for you to consider. You spoke of how you had to "yell at people" at the dealer, and used words like "screw Village VW".... just simply isn't called for here. I get that you are frustrated, but you should just be more selective in your comments. It is a technical help forum, not a bash others forum. There are several members of this forum who are employed there. Furthermore, they are in fact a major sponsor behind this club's annual show. For obvious reasons, many of these individuals have to withdraw themselves from the argument when things get touchy. I was a tech there for 5 years myself before moving to an independent shop. Feel free to ask any questions, or for guidance, I'd just try to keep the negativity to a minimum. If what we did for a living was easy, there would be more people doing it. And, like others, including myself, have said, I do hope you find out what's going on with it. When you do finally get it figured out, definitely post it up to share with others.

Yep... still not mad... just trying to defend other technicians....

Ok ill keep it postive. If anyone wants to try to figure this one out I found another problem. I noticed last night that there was a small mout of fuel puddled at the base of each fuel injector were the fuel injector meets the intake manifold. That makes me think that the orings at the bottom of the fuel injectors are leaking but I just replaced all of them a few weeks ago. Also if I pull the oil cap there is a lot of positive pressure and im not sure if there should be. Anyone know what else could cause the injectors to leak and if there should be positive pressure at the oil cap.

I bet you'll find that the injector leak and the hesitation are related....

ok cool. So more than likely whatever is causing the misfire problem is also causing the injectors to leak. So its not the leaking injectors causing the idle problem. Got it.

Before I replaced the broken PCV valve there was a lot of vacuum pressure at the oil cap. After replacing the PCV valve there is a lot of positive pressure at the oil cap.

Shouldnt there be slight vaccum pressure at the oil cap at idle?

I just took off my valve cover to see if my cams were in time and they were a little off. I started turning the engine over with a ratchet, and the cam chain tensioner moves up and down!! That doesn’t seem normal to a shade tree mechanic like me. I’m pretty sure this thing has variable valve timing so I didn’t know if that was normal or not. Thanks in advance.

It looks just like this:

travisyoung · « **Reply #54 on:** April 22, 2012, 12:03:16 AM »

There should be 16 rollers between the hash marks on the cam and the tensioner will move up and down with out oil pressure

tsabadlk · « **Reply #55 on:** April 23, 2012, 02:57:01 PM »

I did count 16 rollers but both arrows dont match up perfectly with the notches on the cams. If I line up the exhaust cam with its arrow in dead center of the notch on the cam, the arrow that points to the intake notch point to the fare left side of the notch, still on the notch but not dead center of it.

travisyoung · « **Reply #56 on:** April 23, 2012, 05:27:00 PM »

That is correct, they don't line up exactly

tsabadlk · « **Reply #57 on:** April 24, 2012, 11:41:06 AM »

ok thanks, I continue to troubleshoot then.

tsabadlk · « **Reply #58 on:** June 11, 2012, 10:05:31 PM »

I swapped out the ECU with one that I purchased on Ebay for $50 and had a guy in NC disable the immobalizer for $40 and it fixed my problem!! Woot!

Now knowing that the probelm was the ECU, wont someone agree with me that the dealership should have been able to tell me that the ECU was bad after 3 hours of diag?

dubtech · « **Reply #59 on:** June 12, 2012, 04:59:54 PM »

Actually, no. 1 - There's a technical bulletin from VW that has a list of DTCs you should not replace the ECM to try and fix because replacing the ECM is a waste of money and won't fix the problem. 2 - In 10 years of working at the dealer I replaced an ECM to repair a drivability problem ~5 times and they were all on A3/B4 platform cars.
