#5465 of 6629 2006 JETTA TDI, ECCELARATION PROBLEMS, ENGINE STUTTER?????
Dec 03, 2007 (8:38 am)
I OWN A 06 JETTA TDI, WITH DSG, PKG 2, 14,850 MILES ON IT. LATELY I HAVE NOTICED A POTENTIAL PROBLEM. WHILE DRIVING EITHER ON HIGHWAYS OR CITY I NOTICED THAT MY JETTA STARTED STUTTERING WHEN I NEED TO ECCELARATE HARDER THAN NORMAL. I NOTICED THIS PROBLEM FOR THE FIRST TIME ON A TRIP TO TN IN AUGUST, WHEN I HAD TO ECCELERATE HARDER ON THE INTERSTATE. ENGINE ACTS LIKE IT STUTTERS AND DOESN'T WANT TO SMOOTHLY ECCELARATE AT ALL. I AM ALWAYS HAVING THE VEHICLE SERVICED AT THE VW DEALER. I NEED TO BRING MY CAR TO THE DEALERSHIP FOR THE 15K SERVICE AND WOULD LIKE TO KNOW WHAT'S GOING ON BEFORE I TAKE IT IN FOR SERVICE. ANY SUGGESTIONS WHAT MAY BE WRONG?

i was going to try and clean the MAF, to do so, do i have to use 100% isopropanol alchohol?

Not many people have access to 100% IPA unless they are a chemist or the like.
Perhaps you should consider one of the available commercial MAF spray cleaners. Even Carb Cleaner or Brake cleaner should work. (as long as it is not too caustic to the delicate components)
If you do a simple web-search for "MAF cleaner", you will find all kinds of information.
HOWEVER: If your MAF sensor has been contaminated with oil, the high-temp self-cleaning cycle may have just burned it up. Cleaning the MAF sensor will not fix this kind of problem. This is why using one of those "oiled guaze" airfilter is not a good idea.
specific to VWs, there is always the MAF 101
I assume you know about the extended MAF warantee?
In the end.... I STRONGLY suggest you simple use VAGCOM to plot a graph of your MAF while driving. That is the only accurate way to diagnose a bad MAF sensor.

i checked out that warranty letter, thanks, but unfortunatly i dont qualify for it (i have 185,000km on my car)
i did find some rubbing alcohol which is 99%, i did as you said (put it in the ziploc bag and fill with the alcohol etc.) and i am actually just waiting for it to dry, i am going to leave it overnight and then check it in the morning then if its dry i am going to reinstall it and then go from there, also i am putting in a new VW filter, so hopefully it works and save me from having to buy a new MAF
i figure might as well try that first, i mean for 4 bucks (for the bottle) and a lil patience its better then running out and buying a new MAF right away
i'll let you know how it works out
#5470 of 6629 HELP WITH ANNOYING SEAT SQUEEK
Dec 05, 2007 (6:34 pm)
I have a problem with my '07 GLI that VW dealer doesn't know what to do with. The driver's seat squeeks under cornering for months now. The noise is coming out of the right hand side of the seat base (next to the arm rest), right at the crease between the upper and lower part of the seat. This area is covered by plastic, and I do not know where to even begin looking for the source. It is relieved when I press the left hand-side lever on the seat up or down but the squeek starts again soon.Has anyone had this problem before???

How difficult is it to replace the front, driver-side fender liner? I ripped it out going over a curb.
#5472 of 6629 '98 Jetta front wheels slipping
Dec 11, 2007 (12:13 pm)
As wheels go forward they intermittently pause or slip as if on wet leaves. Front axle? Transmission? It's manual 5 speed. Had some steering bolts and seal replaced a month or so ago if that information helps. What may be causing this and to what type mechanic do I take it? Any idea of cost? I am not rich or stupid.
#5473 of 6629 Thanks for the Help on VAG-COM & Temp Sensor
Dec 11, 2007 (1:09 pm)
I started checking this site more than two years ago when my daughter wanted to buy a 99 New Jetta with about 70 K miles. At first I was amazed that there were more than 4,000 messages about problems with Jettas (now nearly 5500!) but she was persistent, we took it to my mechanic (who said I would become his "best friend" but didn't find much wrong)...and we haven't regretted it since. The Check Engine light came on recently (at 90 K miles), which was my opportunity to get the Vag-Com software I learned about here and start diagnostics at home! Turned out the problems was an intermittent Engine Coolant Temp Sensor, which I bought and replaced--again with help from this site. So I saved some money, got a cool new toy (the Vag-Com) and, best of all, the transmission shifts a lot smoother now--an added benefit of having a working sensor. So: Thanks, pat & karens, and all the participants on this site!

What "slips" exactly? Do you mean that the engine races for a second and the car seems to stand still, and then you let off the gas a bit and the car goes forward?
If that's what's happening, I think you have a bad clutch.
