Car is a 2001.5 Audi A4 1.8t FWD model with sport suspension. The part # I am looking for is the one in the picture labeled 2. Thanks.

Certainly. That is the "cap" and would be part #: 8D0 512 089 A

For some added info:
- The cap is the same from 99.5 model year and forward for the B5. Vin split is at 8D-X-200 000.
- Obviously this is a Frontrak only piece.
- There is no difference on this piece for sport vs non-sport suspension.

Thanks! I have been looking everywhere for this (other than the dealship, lol) but just could not find it because I wasn't sure of the name.

Alright, I have another question.

http://i49.photobucket.com/albums/f260/chris164935/IMG_0274.jpg

Part labeled #4 in the picture. It is called a "dished washer" according to Bentley manual. Is that part this part? http://www.ecstuning.com/Audi-B5_A4-FWD-1.8T/Search/Washer/ES252832/

Bump. I figured out that the part I am looking for is not the part in the link. Anybody that can get the part # for me of the "dished washer"? Thanks.

Hmm. I need a little more information. Is this still for the rear suspension? I don't see a diagram that look anything like that in ETKA. The diagram I'm looking at looks exactly like the first one you posted.

EDIT:

Wait...I gotcha. The latest fuzzy diagram you posted is for the pre-facelift rear suspension, which has a bunch more parts. That would not be applicable to a 2001.5 car, only 99.0 and earlier. But to answer your question:

As long as that is the part that goes between the self-locking nut and the part numbered 15 in the first picture, then it is exactly what I need. Thank you!

It is the left-most item in this photo. Part number 357-512-279-B:

However, that part is not applicable to a 2001.5 car. The diagram does not show any parts in between the locking nut and the strut top. I think if you added this washer, it would do bad things actually. If you look at this photo of the upper shock mount:

http://www.ladu24.ee/img/products/400/802-30544.jpg

You will see that the nut is suppose to sit down inside that well. Take note of the construction of the mount. It is metal on the bottom, rubber, then metal on the top. The top metal part attaches directly to the vehicle chassis. The bottom metal part should attach to the shock rod. As such, the rubber connects, and dampens the connection between the 2 items. If you put that oversized washer in there you will be directly connecting the shock rod to the upper metal part of the mount. If that is even possible to do, the results will not be good.

Hmmm... Without the washer, the locking nut sits too deep into the mount and the plastic piece (labeled #2 in the first picture) does not hold the rod correctly. Is the design supposed to be where the shock rod should push into the top of the plastic piece (#2) and the nut is tightened down? This way, the rod can not move out through the bottom (because of the nut), but at the same time, will not bounce/vibrate/slam into the plastic piece because that plastic piece is holding it firmly... Because, I have tried installing it with no washer and the nut reaches the last of the threads on the rod but the rod still bounces around and makes awful vibration noises when driving.

Is there any way you can post a picture of what the locking nut looks like for the 2001.5? My aftermarket coilovers came with a nut, but when used without a washer, it creates the above scenario... They are Rokkor coilovers. Not the best, I know, but something like this cannot still be an issue with their product, can it? It has been on the market for quite a while...

This is the nut:

If you need a washer to make it work, then I guess you have to add one. But I don't think that large factory washer is the right one. I think you need the OD to be smaller than that. Probably something that looks more like this:

That top plastic piece is just a dust cap sort of thing AFAIK. It just clips onto the top threads to keep contaminants out of the mount or whatever. I don't believe it has any function to hold anything still, but I could be wrong.

I guess I'd give Rokkor a call if you can to see what they say.

Wel, without the cap, whenever the car hits a bump there would be nothing to press down on the shock to actually compress it. It just goes up until the suspension hits the bump stop or something else. Then it slams down when the springs decompress.
