It seems that the 7 speed CVT (or multitronic) is fitted to front wheel drive cars and the 6 speed Tiptronic to the quattros.
I am avoiding the CVT as I want the quattro system.
The Tiptronic gearbox is not made by Audi but by "ZF Friedrichshafen", who also supply BMW as well as other motor manufacturers. See here

When you hear Internet Stories about don't buy that brand or the other brand it doesn't make sense as the gearboxs in the same model range (i.e. A4) can be made by a different parts manufacturers.
I think I would prefer the assurance of the quattro system in the A4 as its a proper 4wd (with front and rear diff with a centre torsion diff).
As opposed to the A3 which is a Haldex semi permanent arrangement (mostly front wheel drive).
Oh and may I suggest this as what you might like (no affiliation to seller just a suggestion):

Good luck on your search
Just a quick point on the Haldex and 'proper' four wheel drive.
Since Gen 2, circa 2004, the Haldex system in VW and Audi transverse engined is permanent four wheel drive. There is always a percentage of power going to the rear wheels (20%) and this can be varied by the Haldex unit as traction dictates. Even the Gen 1 was a good system, where you benefit from the fuel savings of FWD but have the four wheel drive when needed. The system transfers torque to the rear when it detects slip of only 1/8 of a wheel turn so it's near instantaneous.
I have the Haldex system on my S3 currently, but was running the Torsen diff quattro setup on my previous A4, and the latter is indeed a bullet proof system, but the Haldex is still a good 'proper' four wheel drive system for most peoples needs.
On the subject of the Audi auto boxes, the problem with the Internet is that you can't judge the reliability of the DSG/CVT systems based on reported failures. It's a self selecting sample, and we don't know how many good cars are out there with no issues. There are a lot of reports though of flashing PRNDS failures, and Audi's default fix seems to be to replace the gearbox controller, and then the box itself if under warranty. Out of warranty, a lot of people have been sending their controllers off to specialist repairers, and circa £1200 later have a refurbed controller and a perfect box.
Admittedly, there are enough reports to put me off, running an older car is potentially worrisome enough without auto boxes to worry about too! If you can put some cash aside to pay for any box worries, it might be worth a punt though?
