Using the Audipage instructions (for the A8)---I thought I'd be set--but NO.

Apparently the filter housing is different--It's black and has one large hex nut to remove.

Anyone know the socket size to use?

The drain plug appears to be the same--a 10mm hex drive---so I have that one covered.

Please help!!

your right on the hex head, but the filter housing is definitly the issue. I only put 10,000 mile on my car since the last change and I do intervals of 5000 miles, so im waiting until the next one to do it. I was recommended a 36mm socket but I didnt try it.

This was just asked the other day, I think they said it was a 36, 38 or 41mm nut......on something like that, if I had a standard size socket that would fit, I would just use it.

Please take a picture of this beast and post it.....I'll update the oil change procedure.

Guess I'll go with the 36mm size and try it---don't have anything that big on hand, however.
Will let all know once I've figured it out.

Basically, The housing is in the same location as the A8---but it's black in color---I don't think it's metal---and has the large hex nut integral to the housing. Not sure if I can get a pic of it--maybe my digital cam has a macro mode.

You just need to put the camera on the floor and point it up when it's up on jacks or whatever you use to jack it up for the change.

I usually take 4-5 pictures of anything I need with the flash on for all pictures, one or more usually comes out okay.

But when I only take one, it never is a good picture!

Will do

Took me about 4 oil changes to figure out that it's very sensitive to torque. I always had a little seapage which bugged me until I used a torque wrench.

very simple:)

The only parts I got in the filter box was the rubber O ring--the silver ring and the filter---am I missing something?

Did find the filter tool (you show in black) on E bay and bot it just now.

if so...check part number of filter. I know old filter kit includes crush washer.

It's a Hengst--#021 115 562 A---and yes it's got the ring and the rubber O ring--bot it at the dealer

sound right?---would hate to get into the middle of this thing and find out not.

old one has the plastic core inside, and I broke filter cap trying to remove the core which now belongs to the cap not to the filter. Sounds stupid, but I did it, thanks to Wendy and poor illustration in ETKA and Bentley.

One last Q
Do I really have to go get a torque wrench to put replace the plug and the filter housing?---Is it really that critical?
I've changed oil on alot of cars over the years without a torque wrench--BMW's etc.
Sure wish Audi had their oil filters right under the hood like BMW

but it always nice to have one. its only 9.99 at:<ul><li><a href="http://order.harborfreight.com/EasyAsk/harborfreight/results.jsp">http://order.harborfreight.com/EasyAsk/harborfreight/results.jsp</a</li></ul>
