2001 Audi A4 1.8T Q Battery Replacement
Battery in our 2001 Audi A4 1.8T Q is dead. From the research that I've done, it looks that:
1) Both Autozone Duralast 48DL and Interstate MTP-91 would fit. Please confirm. Any preferences?
2) Does anyone have a DIY link? Any gotchas?
3) Does the car key need to be out of the ignition during the battery swap? Would it need any re-programming?
Thanks in advance!

Probably want to pickup a universal clamp
only a few bucks and may save you a trip as the replacement may not use the stock hold down clamp. I needed a thin walled deep socket to fully seat my new clamp nut.
Very straightforward, just be sure to use the battery vent hose and route it correctly.
No reason to have the key anywhere but in your pocket during the swap - and I don't remember having to reprogram anything special.

In addition to what was posted below, you'll probably need a new batt bracket.
The replacement batteries are slightly shorter than the OEM battery on the 2001 models. Audi makes a bracket for 1996-2000 cars that you can use to anchor your new battery (reuse existing bolt and toss the existing hold down bracket). Search and you should be able to find that part number. Should cost you around $5 from the dealer.

Great find, thank you so much! Aldo found the radio re-activation instructions
On the Concert, turn on radio, press and hold both the FM2 and RDS buttons, if "CODE" appears on the display, the coding feature is NOT on. If "SAFE" appears, it is ON. To activate it, continue holding FM2 and RDS depressed, untill display changes from "CODE" to "1000", then release both buttons. Using station preset buttons #1 (for first digit) thru #4 (for fourth digit, enter your radio code, then press and hold FM2 and RDS untill display says "SAFE", and then release

Use Interstate!
My indie uses Interstate because they are "all-new" batteries- not refurbished. If you're spending on the battery and have the extra ca$h, I'd recommend going that route.

Which Duralast would fit better in a 2001 A4 1.8?
Duralast 94R DLG --OR--
Duralast 48 DL
According to the FAQ psted here, the 94R DLG is a direct fit for 2001+, can anyone confirm?

What's the process of refurbishing a battery?
Without understanding that, it's impossible to say whether the difference between new and used is real or some kind of marketing ploy used by the Interstate rep.
Lots of things can be remanufactured. The resulting parts could be inferior, better or equal to the original. It all depends on who did it and what was done. Plain jane auto batteries are pretty simple in nature. So I'm not readily inclined to believe that new is better.
