RS4 Battery Draining

[AndyG0409]

Hi all
I'm new to all this so please bare with me

A couple ov weeks ago I went out to start the car to find it totally dead, I used jump leads to get the car started, to go where I needed to go. Next day, again battery dead. I left the car for 2 weeks (as I work away) and ordered a new battery.
On returning home, I fitted the new battery and everything was spot on that day. Thought I was sorted. Went to start the car a couple ov days later, same thing, dead.
Having jumped the car off again and using it that day, reading comments on forums etc........ I started investigating.
It's the Radio, if I leave the fuse out the battery doesn't drain, put the fuse back in and it starts draining the battery.
Car is standard as when I bought it 2 years ago, 57reg B7 RS4, AUDI Navigation Plus stereo fitted (RNS-E) with 6 cd changer in glove box
I have now noticed that the stereo won't work with bluetooth anymore, and that when the keys are out, doors locked the radio still makes a noise like its still running but the display is off, and the cd changer stays lit up. This is why it's draining my battery!!!!!!!!!
I've been to see someone with Vag Com, once he plugged his machine in I had numerous faults showing "Low supply voltage" on numerous items. Having had all this cleared, the car shows no faults but still have the same issue with the radio
Guy who I seen with Vag Com didn't really know anything else

Has anyone on here had similar problems or know what might be the cause?? Is it the Radio/Cd changer or something else??
Any help and advise would be greatly appreciated
I live in the North East, Teesside area and would quite happily meet up with someone who could help me out

Thanks

there is an update to the Radio MMI firmware to correct this.
what version of the software are you running?
Easy fix - just find anybody with a more recent sat nav dvd than yours and it should fix it. Even an ebay copy would be fine. it won't wreck the old maps.

Hi there

Just got information from the radio
SW: 0550
HW: H73
Map: M1N061018_EN0603

Hope it is just a update issue, really frustrating as no one in Audi wants to help, there just interested in wanting money to take a look at it!
Is there anyone in the teesside area who might have a copy ov this update I could Borrow/Copy/Buy
Honestly, any help would be appreciated

Thanks

The latest firmware for the RNS-e is 0650, as mentioned you'd need a later Nav disc and it will update the firmware upon DVD insertion.

There could be a couple of other things to check out. Perhaps there is some wiring earthing out like the Bluetooth module if it has just been shoved up behind the glove box without too much care for the loom. I'd also have a look at the thread below, your relays could be breaking up causing the numerous power/signal fault codes.

As far as I remember the Bose amp will still be on for about 30 seconds after you lock the doors which is probably the noise you mentioned. Does it carry on for more than 30 seconds?
