Does anyone know how I can replace the battery without going back to the
dealer. Im at 53k miles right now, and I don't want to spend more than I
really have to.
I did buy a 46-D battery from Autozone but that thing is much smaller than
the Audi one in dimensions. Also the the Audi battery has a little
transparent tube that comes out from the side that the Autozone battery
Anyone has any ideas what I must do to get a new battery in there?
Putting money into a high-quality battery can be a good thing. They
last longer, are more reliable, and have better winter performance (if
that is important to you.) Having a 7-year battery can give you good
Without some sort of spending parameters, it's hard to make a
recommendation. IIRC, many of the batteries come from the same
manufacturer, and are merely rebadged to sell in specific stores. I
have a vague recollection of this being discussed in some automotive
newsgroup about a year ago. I realize that doesn't help much, but it
gives you a starting place. Ooops, pardon the pun. ;)
Get a good quality battery, with the same power CCA as the OEM unit for your
car, the little pipe that comes out is to divert any acid that may come out
of the battery away from the battery tray & help cut down corrosion, think
the way the newer Audis are designed is pretty bad, pretty sad when Audi
build cars that wont even let the owner change their own battery, a easy way
round this is to source a remote keyfob 12v battery, connect or solder 2
pieces of wire to it, bare off the ends & wrap the wire around the battery
lead connections when you remove the battery, thus still giving current to
the cars brain, put your new battery on & remove the small battery & wires,
car wont know any difference!
What are you talking about? I changed the battery on my A4 and all I had to
do was reenter the radio code. Big deal! I bought my replacement battery at
Autozone and it was an exact fit with the little tube as well. The OP may
have got the wrong battery. Here in Arizona, batteries die quite quickly -
often in three years, almost certainly in five. I buy one at a place like
Autozone and then get it replaced under warranty when it dies. Even
pro-rationing doesn't wind up costing much.
On newer Audis when you remove the battery it causes an error code which
sometimes makes the engine rpm tick over higher than normal, around 1600
rpm, this needs to be re set using the dealers plug in computer, or
somthing similar, there are 2 old sayings that come to mind, 1. you learn
something new every day, 2. when in doubt leave well alone,
This is called throttle body adaptation, or TBA, and needs to be done every
time power is disconnected from the ECU. However, you do not have to go to
the dealer to perform a TBA. All you need to do is, after you connect the
battery, turn the key in the ignition to second position (but not turning on
the engine), and wait for two minutes without touching the gas pedal.
During that time, the car performs the TBA. You'll hear all kinds of
hissing noises coming from the engine bay while this is taking place. After
2 minutes, you can start the engine.
The error code will still be stored in the ECU indicating that a power loss
occured; however, it is harmless and will not cause any warning lights to
show up on the dashboard. It can be erased the next time you wind up at the
