Or you could ask nicely

...someone might give you parts list and diagram. Let me look, ETKA wasn't wanting to work on my W7 machine.

I can't get my older version to install on W7 for the life of me...installed it twice on XP, transferring it over to another XP machine to try another install.

For the record, have 3 XP machines, 2 W7, 1 W8, 2 Mac...product testing!

I'm in for the Windows 8 testing! haha

Installed fine and even a mention of a bug fix for W8, should be good, will plugin later...

Ok, hooked up the vagcom and simply logged the start up... I'm guessing the 0.5 is my problem correct? this is block 090...

Here are my numbers that should be a ballpark for you. My assumption is that as the cam adjuster pad wears down, you get closer to negative numbers. The side that was reading -7 for me was completely gone and the cam chain was riding on metal, the rest of the plastic foot had shattered and was scattered about the cylinder head (I think that's correct terminology). The drivers side is much easier to open up and look at, passenger is a pain and will need to be in service position. Besides having screwed up timing and misfires you've also got those chunks of plastic floating around in your cylinder head, which I swear I could smell, extra burnt plastic smell with the exhaust.

Rough idle and flashing CEL on startup; upon scan the driver engine bank 5, 6, 7, 8 was mis-firing. Upon scanning measuring blocks (70 & 72?), the cam adjuster on driver side was reading -7 (not working), while the other reading 16 (working).

What sucks is I don't even wanna drive it to the shop down the street I have access to, but I REALLY wanna use the lift... it clears up when warm tho still. grrr what to dooo

Yea, mine was really nasty and lumpy sounding. Used my insurance and had it flatbedded to a mechanic. Free towing for a breakdown seems like a common bonus with policies.

Anyone have P/N's for the plastic guide pads? Can't get replacements thru the dealer I found out.

Some found on Ebay.....anyone?

**hahnmgh63** · March 1st, 2015, 00:32

For the piece of mind I would stay away from the Hong Kong sellers though.

There isn't an Audi part number for just the pads. Audi wants to sell you an entire tensioner. Your only options as far as I know are ebay, Amazon, and the like.

Priced everything out, still went with the Blau Kit... just the best option at this point trust wise. The included parts in the kit look good.

My car got towed for free by amex lol, she's on the lift now, start opening her up monday. Been waiting on timing tools to show up this entire time. Can't believe how slow people can be to ship stuff.

The KW values change based on whether the tensioner is in advanced/torque or retarded/power setting.

KW values do not, cannot, correlate to any specifiied tensioner piston position(s). It's based off the cam sensor reading.

The value is monitored and correlated as chain stretch to the DME. (it does on the newer cars)

Normally I'd mess with the base (cam) timing value to alter power characteristics. Just wish I knew both the internal engine clearances, and tolerance values to work within.
Seat of the pants I'd add in more retard (which will naturally occur with wear). Opposite of what I've done to many a NA motor over the years for most people. Not much, but enough to wake up an older engine. My best result on a 944 some years ago. Owner came back wide-eyed and joyful some weeks later.

See what happens with the new cams going in.....

just opened up mine and replaced the half moon and tensioner seals as well as cam seals and plugs. all these were leaking as I was in there to do the timing belt. I was keen to check out the tensioner pads but I had not ordered the parts. all of them looked good, only minor wear on the driver side top pad. mine has 200k (kms) on her, I just put her back together and will do them next timing belt I think.
