i've read through a couple threads and noticed that some people have had some trouble figuring out whether they have an early awm vin or a late awm vin when ordering the ecs timing belt kits. my lucky numbers are 68d41a083217. any help is appreciated!

Judging by the numbers posted by guy02, your car would be a "late" awm vin. The decoding is as follows:

-"From VIN: -8d-1-042385" means "this vin and greater, dashes are wildcards so ignore that character"
-Your VIN is -8d-1-083217
-083217 is greater than 042385, so you are in the late crowd.

My question is, what *exactly* is the difference between the 2 kits. Specifically. Anyone care to enlighten?

i read its a difference in the tensioner and the release mechanism on it. one has a pin and another has a bar.
btw i was waiting for you to chime in because i was sure you would have the answer, thanks!

You've got a late VIN..
Here's a link to our OE AWM TB Kits..

Thanks, Motown.

Yeah, did some close looking at the kit pics on ECS' website. BTW, they don't have the correct photos for every kit, which makes things a bit confusing.

It appears the Hydraulic Tensioner is different. The later AWM use the same piece as the AMB (B6 1.8T). The difference is the retention mechanism: flat bar or "grenade pin".
It appears they've changed the large tensioner roller as well. Most of the photos appear to be exactly the same, but one of the "kit" photos showed the B6-style tensioner roller that has the built-in tension adjustment. That tensioner is famous for causing a bit of grief for the B6 guys, because you have to adjust it properly.

I would imagine the kits/tensioner/rollers are completely interchangeable and are just updates to the design and nothing more. Seeing as all the gears (crank,cam,water pump) are identical and the belt is the same - this must be the case. I'd actually prefer the "early AWM" kit myself as it doesn't require any critical tension adjustment. The newer tensioner roller design actually requires a special tensioner wrench, but there are certainly ways around that.

The difference between the early and late VIN AWM timing belt kits is the hydraulic dampener and the tensioner pulley. The older VIN kit comes with a dampener that has a threaded hole on the top face of the unit and has a grenade style pin that you pull to release the plunger once installed. The tensioner pulled is a fixed style that doesn't have an adjustable tension tab on the front. The newer VIN kit has a dampener that doesn't have the threaded hole I mentioned and instead of a grenade pin that you pull it has a flat forked pin that retains the plunger. The tensioner pulley in the newer VIN kit has a rotatable tension adjuster thing on the front. I can go over how you set the tension, but you can also find some pretty good procedures in other threads. I will try to attach some pictures...http://www.rockauto.com/getimage/getimage.php?imagekey=1120213&imageurl=http%3A//www.rockauto.com/info/Dayco/84109FRO.jpghttp://www.rockauto.com/getimage/getimage.php?imagekey=1120209&imageurl=http%3A//www.rockauto.com/info/Dayco/84110FRO.jpghttp://www.rockauto.com/getimage/getimage.php?imagekey=1297652&imageurl=http%3A//www.rockauto.com/info/ACDelco/T43025_Primary.jpghttp://www.rockauto.com/getimage/getimage.php?imagekey=1297641&imageurl=http%3A//www.rockauto.com/info/ACDelco/T43028_Primary.jpg

I just make my own manual tensioner with use lf an older vw one. no need for a hydraulic tensioner, thats just another thing that can fail
