Is there any signs of water ingress near the relevant modules?

 

Already checked for that briefly. I know it has rained a fair bit, Infact I don't think it stopped raining since the drought was announced! But strangely the problems only occur later on the day when the sun is at full blast!
The sound cutting off intermittently has been occurring for a while but only briefly, but the cd is now not just cutting out for a second or two but is switching off and the radio comes on and then I can't select 'CD' because its not registering any discs, but then a few mins later it then let's me select CD option.
Plus we've had no rain for over a week here.
Just don't want to be left with no drive or audio.
Don't really wanna fork out however much it will cost because i'd rather recon my turbo or engine! Put my money to better use! Cos I know idrive, Bluetooth, sat nav costs a fair bit

 

Hi,

Just to mention, I've been having the exact same issue on my car an 05 530D with Pro sat nav and CD changer. I could be listening to the CD and sometimes the music would stop for a few seconds then continue and other times the music would stop and drop to the radio. Again like you it has only been happening later in the day when its been hot. I'd like to know other peoples opinions, maybe a software re program would fix the issue ?

 

Its absolutely fine in the morning.
Its just after work i seem to have the problem and when its been v. warm.
Oh well cant see it being a major issue..... when was the last time we had a really warm summer????? 2006??
I always hope for a hot summer and sods law we probably get a scorcher this year and no music!!!!!
Oh well looks like the old headphones have to come out, connect to my phone which will also act as my hands free , and it has sat nav!!
Lets hope it doesnt come to that yet!!!

Hi there!
I am having exactly the same problem, it happened today for the first time.
I got to the car after work, it was boiling inside...
It was behaving as yours, phone loosing connection and sound going of, I have never loose the cd player, but was happening under cd or radio.
At some point and wile driving the iDrive restarted by it self, but came back on with the same issue.
During this time I have noticed that the iDrive was sort of irresponsive, and slow to respond to any comand...
Have you managed to sort yours?
Did you update it?

 

No one?
Well, anyway, today I had the same issue... After left work I had to do about 60 miles, and during the entire journey I have the above issue...
Stopped the car for about 3 hours, drive back home and no issues at all!
As anyone solve this?
I am willing to visit the dealer and update the modules, if that sorts the problem...

 

Now the suns out, problems again!
Been doing some reading around and apparently could be a faulty 'ccc' module. 'communications control computer' module? Apparently its not too difficult to replace but it will need recoding if replaced. I'm not sure the cost of the module but there is sum1 on ebay who will charge I think around £100 for labour and recoding but he only covers London area. Any further then its 50p per mile! One way only (so you're not paying for return mileage)

 

So, I do presume you have not solved the issue on yours, or have you?
A faulty module does not realy convince me, I mean, if it happens only on hot whether it might be more to do with some sort of cooling system... I might need to check if the fan on the module is working... but because i also loose the bluetooth connection, it might be the telematics module...?:confused

 

No not sorted the problem. The last time it happened was in may when we had hot weather. It was ok until this recent warmer weather. If its hot everyday then I will need it repairing, but what are the chances of hot sunny weather here in the UK! Lol
Forgot to mention that I also lose blue tooth connection.

 

The Bluetooth connection is the one that strongly makes me believe that the problem is not the ccc but the telematics...
The telematics is about £100 on eBay, so just need to managed to get my progman working...
However I will have a look before start to spend money...

 

I might do a detailed search on the net and see if I can come up with any more info.
Diagnostics hasn't come up with any errors, well at least it didn't do the last time I had plugged my inpa in.
If I take it to more than garage then I can guarantee I will get more than one opinion as to what the problem is!

 

I will connect DIS to mine on the next couple days and will post the results...
But to me, and repeating myself, the problem is the telematics...
Would be great if you find any more information about it...

 

done some googling and when searching for "bmw cd audio cutting out in hot weather" alot of people seem to have similar issues and most of the suggestions point towards the amplifier overheating???

When ever we have hot weather thats when mine starts playing up! and sometimes when CD cuts out then I get a high pitched sound then audio returns but to the radio. It doesnt let me choose 'CD' option as it does not recognise that I have any CD's loaded in the changer.
A minute or so later then the CD comes back again.
The high pitched tone only happens when its really hot, yet its cool inside the vehicle as the AC is switched on.
When its not that hotm then no hich pitched tone but the audio keeps cutting out, whether CD or radio.

These are they symptoms and I believe a competent clinician somewhere can come up with a prognosis!!

 

point towards the amplifier overheating???

Something along does lines make much more sense to me!
Silly question, where is the amplifier located?
Is incorporated in the ccc?

Any way,have just run DIS and was no codes...

Just out of curiosity, today I have connected Progman to encode the auto folding mirrors, and get a message that the ccc needs to be updated... It might helps..
There is any one that can confirm that the issue is less prone on later software versions?

 

Have a read of my post about the mULF Module here
http://www.bimmerforums.co.uk/forum...o.uk/forum/f15/2004-e60-530d-ulf-bluetooth-module-goosed-frozen-idrive-t118221/

My symptoms were the same as you guys, easy to check, just unplug the mULF module in the boot, takes seconds and my Audio, CD Changer burst back into life.

Not solved it yet but it is in progress unless I've been scammed for a new module.

 

I am in a same boat like you guys, just noticed this morning that my radio cuts of, not cool at all. So I tried going to Entertainment setting in my iDrive where I can isolate the fwd or rear speakers, let and right... I figured that if I leave the rado playing just on rear speakers, the sound would not cutt of, but as soon as I try to add some of the forward speakers into a mix, it starts cutting off. Also if the volume is set higher sound setting normal it will constantly keep cutting of. I haven't tried messing with the components yet, but to me it looks like the amplifier is going bad.

 

More issues

I brought my 2005 530i last week, took it for a nice long drive, 100 miles, and not only had issues with cd, radio and Bluetooth but also had the car turning off the auto air con and when I parked the rear sensors thought I was touching something even though there was nothing behind the car. I'm contacting the warranty company as instructed by the garage to get BMW to fix this, if tey do I will let you know what the issue was.

 

As we are having a quite good summer this issue is more and more obvious now...
On my case this is what I have found:

Outside teperature under 21c - no issues
Outside teperature between 21 and 24 - audio cuts every now and then as the bluetooth connection, more frequently as the temperature raises...
Outside teperature above 24 - What a mess!:jaw-dropping the system becomes irresponsive, the I-Drive controler spins freely, no audio, as I now have the MP3 enabled, the song stops completely, and one or two minutes later starts working again for another 2 or 3...

Now, got DIS connected and found this:

The outside temperature that day was about 24,5c...

At 59c should not the fan be spinning?????:confused
The fan is working, cause I can hear it if I test it with DIS...

 

Oh well winter is approaching! Pump up the volume! (Now who remembers that? M.A.R.S!)

 

Oh men, I think I have found the root cause of this problem.... shame on me, as I probably have not been paying attention enough when investigating the issue...
Still have to make some tests to make sure, but....

Today, and probably for the first time I got to the car with my phone off, flat battery... so no Bluetooth connection with the car...
24,5c outside temperature, and all the way to home with no problems, I even push the volume up, and all good!

Chr15gb, I am probably on the same boat you just came of... further tests will say.
Will might seek for you experience on this...

Will post findings as soon as I have them!...

 

What I noticed when I first started having this prob was my bluetooth connection intermittently turning off and on so I've turned off my bluetooth on the phone only to still have the annoying problem. so I dont think thats the cause, well not in my case anyway.
One day if I really get peed off with it, because I can assure you it really can bug you, especially when you've had a really bad day at work and you just feel like yelling out "doesnt anything work properly!!!!!???" I'm goona go to the stealers and see what explanation they can come up with!!
Talling about the stealers Ive yet to act upon my recall letter!

I had my one sorted last month, when they also updated the car, with no avail to this problem...

I still need to investigate further, I will be also physically disconnect the module to see what happens... as chr15gb isolated is issue that way...
Still puzzling me the fact that the ccc fan was off when the board was at 59c... but hey, it looks that the hot wether is fading out, might need to wait till next year...

 

Same issue here

Hi chaps.

Brought a 525 yesturday, having the same issue with stereo cutting out and idrive slow to respond. Mine occurs when it's cold. Can you let me know if you managed to sort it. Or give me some pointers of what to check and were to check it please. It is a real pain this issue

Well my friend, if yours is doing it when cold, you are in the wrong thread! :hihi
Just kidding...
I still awaiting for the hot weather to start to check it...
Yours seems to be a different issue from the ones above...
Try to disconnect, for example, the Bluetooth, and see what happens...

 

Welcome to the forum mate.
As mentioned it only happens when it's really warm so judging by the weather we normally get you can see its very rare this occurs. Lol
But on a serious note I haven't got it sorted but usually occurs when we get a few days of scorching weather in the summer.
The other thing I noticed is that it generally happens when I'm blasting the music and not normally at low volumes.
Amplifier probs???
No doubt this thread will be buzzing worth activity in the summer! !

 

2004 530D Intermittent iDrive Audio Cutting Out

Hi All,

Wondering what the latest update was on this topic?

I bought a 530D Sep 2004 and the first thing I did was take it into a independent to get all the CIP programming done which now means I can play MP3s. I haven't owned the car that long but I'm not sure if the updates have inadvertently not helped with my intermittent issue with the iDrive freezing. As per the previous posts my radio / CD / Changer cuts out for a few seconds and come backs on (this doesn't happen until at least 50mins of driving) and this happened after the first few weeks of owning the car (also after taking it in for the CIP updates but I'd only driven once on a long journey prior to that, but with no problems).

It happened again this weekend (happened to be quite warm out and the time before it was quite warm!) but what I did notice was my Bluetooth connecting / reconnecting each time the audio cut out. I have an iPhone 4 connected via the Bluetooth. Anyhow, when it finally froze / crashed the iDrive could free spin and everything was unresponsive (strangely the Nav maps still displayed my correct position). What I did do though was disconnect my iPhone Bluetooth at the next junction and everything came back to life. I haven't driven it on any long journeys since but now I can decide if the TCU module (Bluetooth connection) is faulty OR it doesn't like the iPhone 4 (as it's the Sep 2004 model) OR it's the warm weather OR the Sat Nav DVDs (they're 2013 maps burnt onto Sony brand DVDr's and I've read this can cause the system to crash).

I've also taken back to the independent who had the car hooked back and found no new faults. (I did notice in the quick test report (when I first got the updates done) there was several errors on all the units (the specialist suggested they've never been cleared as the CIP had never been updated) but one of the errors was " TELEPHONE (TCU / ULF) D690 Ring break diagnosis has been carried out).

I don't fancy spending £000s replacing the TCU if it's not the cause so my plan is when I'm next on a long drive I intend to have no Bluetooth connection to see what happens... then if I have no problem I might Bluetooth my other Nokia phone to see if it's just the iPhone 4 (If that's the case then I can live without the iPhone connection for the car and just use my work phone).

 

hi every one i am having same problem with my cd and bluetooth but my bluetooth will not connect at all now sreen as gone completely of a couple of times now could do with some help getting me down

 

We've had warm weather and surprise surprise the problems have appeared again!
As the original poster of this thread 12 months ago im still keen to know whether anyone has had this issue successfully resolved.
I sense anorher summer of idrive discontent

 

Wondering if anyone has a solution to this one? Now that we have some really warm weather my radio drops in and out and the bluetooth is constantly disconnecting and reconnecting - most annoying. I've disable bluetooth via iDrive menu and will see if that helps at all.

Any info appreciated.

Cheers

 

Ive tried disconnected bluetooth and the problem is still there!
This is the 3rd summer I've had this car and its getting really annoying and what I may do is listen to all my music via my phone and some dr dre head phones!!
