maintenance! if basic stuff doesn't do it, the best way to fix it is to get a REAL diagnosis from your local vw dealer. many shop can do obd2 testing but vw can really pick the brain of this car. my vw has been "home" 2 times for diagnosis. once at 149,000 and just last week ar 210,000. most mechanics don't wrench in german.

Before you spend another dime, take one of the battery cables off and leave it off overnight. Actually, thirty minutes will probably do, I just say overnight to be safe. This will give all the computers and other electronics an opportunity to reset. You will loose any presets on the radio or seat adjustments etc. Sometimes just rebooting the system will correct the oddest problems. If this fails you should go ahead and either diagnose the car yourself or have it done professionally. Many shops, and any VW dealership should be able to help you.
You don't sound like a do-it-yourself guy, but if I am reading you wrong this might help. Some auto parts places will rent or even loan you the diagnostic equipment. Failing that, most of the auto parts chain stores offer testers complete with operating instructions. In my experience a tester will cost 2 to 3 times as much as a one time diagnoses. With all the computers and sensors that is probably the only way you will find the problem unless you just "dumb luck" into it.
A Chilton's or a Hayne's (or both) service book for your car would be a good investment, they normally have trouble shooting charts and will provide instruction on maintenance.
BTW, don't just start randomly fooling around under the hood. I'm reasonably certain you vehicle is equipped with air bags. If you short out the right system or sensors you can accidentally deploy those things. You don't want to know how expensive those repairs can become.

Could be you have some carbon build up. This happens on cars the get driven a lot over short periods or in stop and go traffic. A good shop that works on German cars can look and tell you. Do not have a local parts store plug in an tell you what they think is wrong. The unit they use is only for OBD 11 and has no way of fixing rough idle. Also VW has had some problems with the throttles on some late model cars again for the 50 to 80 bucks you'll spend at a quality German shop its cheap compared to the hours you may spend guessing.

Ok having to raised four kids on my own. I have had a LOT of lemmons. The only thing that comes to mind when is doing that if you did the tune up your self something like a wire was not put back correctly, if not that then your fuel line is clogged up enough for you to push it thru when you step on it but not enough to let it idle correctly, or try your timing it might be off.

what 12 months is the circumvent? And no its no longer a competent theory to throw aspects at it .After replacing each thing on it i'm effective you'll locate the region finally.It does sound like an egr or conceivable a vacuum situation although. yet it really is from what you defined up to now and in my opinion I do imagine the Bosch plugs will be a contributing element

If your car is checked at a VW dealer,a tech. will find some diag. codes or faults.It will take a VW dealer to find and fix your problem.Your local repair shop has not the proper equipment.
