No code on those cars.
The radio module is in the back of the car.
Is it a touring or saloon? In the touring it's underneath the boot floor

Do you think the whole module is fried?

 

It is a touring. Maybe a fuse then?

 

Or a bad connection.
Find the unit under the boot carpet and see how it looks.
The fact the sat nav shows up suggests it's not completely fried. The sat nav sends signal to radio module that then relays it to the screen at the front.

Ok, one problem down and a new one apears.
The problem for the radio was the fuse inside the radio module, it was not blown but it had a bad connection, pulled it out and put it back in and the radio started working!
But now i have a problem with the sound, when i turn on the radio there is this high frequence pitch like distortion or something. it is very loud. If i put the volume up it makes that sound louder, if i turn off the sound or the radio it disapears. What could that be? I dont know if it is relevant or not, but the cd changer doesnt read discs, i have 4 discs inside and the nav unit says that every slot is empty.
Maybe it could be the amp? or the bm53 thingy?
Sorry, i dont know much about bmw and there systems
Also i have noticed that 2 of my parking sensors doesnt work, is there a diference between the round ones and the square ones?

 

Did you do the reset by disconnecting the battery?
Can you tune in to a station on the radio?
Take the magazin out of the cd changer, take the cd changer out of the car, take the cover off and very gently clean the laser with a q-tip moistened with alcohol. Try again.

Yes, i can tune in a radio station and i can hear it, but that distortation very much louder then the radio

 

What is your battery voltage? 12,6 V is fully charged.
Look at the cd changer, check all connections to the amplifier, if the cd changer starts working again and you have the noise there also then I guess your amplifier has a problem.

 

Will check it tomorrow, it is already midnight where i live
As i understood from reading around the internet the amp is built in the radio module and that module is called bm53 yes?

 

not really familiar with the Touring but only the most basic systems did not come with an amplifier. Did you check under the flooring in the back, the amp should be there, or next to the cd changer.

It's starting to sound like you're not in North America. If you post the last 7 digits of your VIN...we can decode it to see what it is you have.

Depending on what set-up you have...the amp could be free standing. The audio systems optioned here in the states ALL had a separate amp...and it could be the regular amp or the DSP amp...and you could also have the MID (Multi-Informational Display) which was paired with an in-dash radio/cass or radio/CD player...or you could have the onBoard Nav monitor.

In other markets BMW also offered the IRIS (Integrated Radio Information System) which came with the amp built-in to the radio. If you have the BM53 or BM54...then you will have a separate amp as shown in the topology chart back in post #6

And here's a link to the TIS (that was posted back in post #6) that lists audio system complaints in regards to radio reception and what could be a possible cause: https://www.newtis.info/tisv2/a/en/e39-540i-tou/radio-aerial/YFooQGx

 

He's probably in Yurrip, since he has an E39 diesel.

Why are people so cagey about where they live?

 

Yeah, would be a great help if people would write what car they have under "Mein Auto" (my car) but maybe people dont understand what that means. Also, location would be a great help.
Many doesnt want to reveal their VIN number either (is the car stolen?).

 

Sorry, i am new to this. Yes, this is Europe and the last 7 digits are GW47374, tell me what you get out of decoding it
And today the problem re-apeared, again i cant turn on the radio, and the orange light wont go on. I think when i will have some free time i will go to the wreckers and take out a radio module from a diferent car and test it on my car

 

You can do the VIN yourself, just search for BMW e39 VIN decoder!

Ok, one small but big update for you guys, which i think will be the end for this discussion!
Today i messed around with the audio again and noticed, that the high pitch scream noise IS NOT coming when i have the AM mode on! tape, FM radio has that high pitch sound! So what do you think it could be? I kinda think either the the big screen unit or the BM54 unit is the cultprit!

 

Did you look at the cd changer?

 

didn't have any time. Will try to do it tomorrow, plus the changer case where the cd's live is very hard to get out, i have to like knock the case down for it to come out.

Do you think the changer might be at fault?
