I have a '05 R1200RT, I just changed my Battery and now a few seconds after I turn on my key, before I start the engine, I get a Warning I've never seen before "DWA:" and then what appears to be a partially charged AA battery. I can find nothing in my owners manual that describes this warning.

Dick, DWA is the alarm system.. The battery shown means the alarm batteries are running low..

I guess the first thing to do is ride the bike a bit to see if the DWA low battery warning goes away.. If not then open up the alarm box,, (the alarm should be in the tail section on the RT) then replace the batteries..

It may also be the battery in your key fob. I changed mine on the advice of the BMW dealer and the warning went away. Try using the other key fob and see if it still does it.

Link to a recent discussion on the DWA warning and an R1200RT.

There is a separate small manual for the alarm system that describes this warning.

As others have advised, it means that the backup batteries (2) in the alarm (DWA) module under the seat are depleted. The alarm will continue to work, but it will not sound if the main battery is disconnected.

The alarm module has no way to sense whether the fob battery is weak that I am aware of. The fob either works or doesn't. Funny, the things that dealers come up with. confused I used to work at a BMW dealer......

Yes, the alarm is one of the only options that can be added at anytime. You may have to get with the dealer to update the computer to have it recognized.
