I know you were asking Aspen for the part number and TSB referenced but I thought I may as well put what I had out there too.
The original factory part that failed last year has an Audi logo with part number 4A0 905 849 This part has W. Germany stamped on it so presumably it was made there sometime in late 2001 and lasted for 14 years before becoming "sticky".
I replaced it with a switch that has part number 4A0 905 849 B (the B is the difference) from Napa that came in a box that says Made in China. This one lasted six months and maybe 100 starts (haven't been driving much) before failing to move the key back under spring pressure and would be under warranty if I could only find my $9 receipt...

Well yeah, the same part was used at least as early as 1988 at Audi. I have no idea if they would remove the "W." in the existing tooling if they manufactured the part after '90. In my experience, Audi and VW plastic and electrical parts tend not to sit on a shelf for too long after being made...

I've done it once in each car and think it would probably take all of 10 minutes at this point...
I would at least try the $30 fix before spending $250. Last time I swapped mine out it took me a whopping 19 minutes - if it was a big job, then yeah I'd spend the extra $220 so I didn't have to do it again. But, this is really a simple DIY fix, especially if you have already done it once - I've had turn signal bulbs that were harder to change out. Take the money you save and buy a new set of motor mounts, which will take you another 20 minutes or less to replace.
It is too soon to say "fixed for good" but my indie says he hasn't had one of the TSB assemblies go bad yet.

I ended up deciding to use Warehouse33 and ordered ONE OF EACH of the cheap, $6 ones and the $30 ones (actually $26). When they arrive I'll look to see if I can see any difference between them externally or if I think I just got ripped for buying OEM. Either way I'll install the more expensive one and keep the cheaper one in the glovebox along with the mini screwdriver just in case. If I can find my receipt from NAPA I'll take the bad one back and get yet another spare which I'll probably try to pawn off on one of you homies...
Thanks for the lively discussion!

I received the package from Warehouse33 but haven't gotten around to replacing anything yet.
As you recall I ordered one each of the cheap $6 switch and one of the $26 ones.
When I opened the package I assumed that the more expensive one was the one in the full-color box but I was mistaken.
The cheap one ($6) was in the full-color box with a sticker that says the part number, JL Germany and "Made In China" on it, the box has an "AIC" logo printed all over it. The switch looks pretty much the same as the others but is a slightly different plastic texture and has a sticker on it 2015.10 that probably denotes the manufacture date. The part also has the AIC logo embossed into the side. It does not look obviously cheaper or worse or lower quality than either the other new one ($26) or the one that was installed at the factory and came out of my car after 14 years of use.
The expensive ($26) one was in a plastic bag marked "Made In Spain". Interestingly it looks IDENTICAL to the one that originally went bad in the car last year. All the mold marks are in the same places and all the markings are the same, including the Audi logo and the part number, up to and including the "W. Germany" molded into the bottom (even though the packaging clearly says it was Made in Spain. The label on the package does have the part number 4A0-905-849-B but then has the suffix "/56" right after the B so it reads 4AO-905-849-B/56 I have no idea what the /56 denotes.
I will be putting the more expensive switch into the car. I figure the real original one lasted 14 years and the cheap one lasted less than six months. Hopefully the more expensive one will hold up this time too.
Once I take the bad Chinese one from NAPA out of the car I will dissect it as well as the bad original one that I held on to from last year and try to compare internals. I'll most likely get to the dissection in the next couple of weeks and report back again.
