Have a 2004 325i and when stero is off the speakers still make a static and thump noise. Any ideas on what it could be? Dont really want to take it to the dealership and charge me a arm and a leg for it. Thanks

Mine does exactly the same mate, but only the rear nearside speaker , as the front ones have stopped working.

But mine does it not very often, and does it while the stereo is on and off.

I think its just a loose connection, I must check it out one day.

No amp. Just the factory speakers and player. It just does it on the back two even if the radio is off. When i do have it on sometimes i can hear Music then it just goes away. I would give it a tap when driving and it would make all sorts of noises through the speakers in the back. They dont give a lot of room to work with on the wiring harness to see if there is any loose connections. Im just at a loss of where to start. It just started doing this yesterday. I opened the trunk but the connection to the two speakers back there were good. I noticed when i took it out i could tap on the case and it would go through the speakers also. Im thinking maybe a loose ground some where? If so where do you find it to check it out?

I took my radio out once to remove a hands free kit, it

Im going to look into it next wee.

But Val is probably right, we could end up tracing all cables back to find the problem.

I need to do this, as after xmas I want to upgrade my speakers.

well i opened up the player and took it all out and saw no problems with the circuit board or anything. put it back in and it starts to work again. i took the car out last night and on the way home it started acting up. so i leave it pluged in and pulled out off to the side while there was no static going through and messed with the wires in the harness and thats when it started doing it. they don't give a lot of room to work with it unless im guessing it goes up under neath the driver side where i will have to reach up in there and pull it out to actually see whats going on with it. so this could get interesting. guess we will see what happens. thanks and i'll keep you posted on what i find etc...

I got to thinking about the pins back there but i even tried to see if i could maybe pull them out under the dash but still no room. By any chance can you pop those pins out one by one and look at the connections to see if it may need to be re soldered? I dont want to get them confused on where they all go if i pull them all out at once. There are 15 pins and it looks like you can push them out with a small screwdriver but i dont want to take any chances on messin something up. I know some friends who have dome it to other vehicles but i just dont know about these

Well i found the ground wire and amp in the back of the trunk driver side and everything was good. I moved around the wires that go into the amp and nothing. But, when i do that behind the head unit it will make all the noise. I have heard that the head unit could be bad although i can't imagine the harnes making it do that. I would think that if it was the harnes you would still get Music but it would just be distorted. That's what has me to believe that it is in the head unit. Any ideas if BMW can somehow test it before i decide to get a new one? Any info helps. Thanks

      Morning Damien Welcome to the Forum An internet search may give more information particularly the US sites Your BMW Dealer may not have seen it but that doesn't mean its not there. I have also read that the new cars when plugged into the Dealers system now have to be linked to BMW Gmbh They really don't make it easy do they, Technology is great until it stops 😅 Hope they can sort it with a software upgrade or something simple so you can enjoy your car again (sneaking around in silent mode🤣) Dave

      Amplifier replacement.

      You are welcome Danny A BMW Dealer will not repair anything, they just change components at the Customers expense and no regard for cost I would use a BMW Vin Decoder site put the Vin number in and you should get the original build sheet Look at the list of Codes S676A is the basic Hi Fi system S688A is Harmon Kardon S6F1A is Bowers & Wilkins. Then you will know the starting point and will be able to make choices on how you move forward. BMW Designers are good at hiding components in places where they can get flooded, several models over the years have had Nav/Audio in the boot buried under the floor. Plus many of those models had a boot that could become a swimming pool if a seal was damaged or failed so moving your amp out of the danger zone makes sense. As you had the 40 amp fuses melted check the speakers as well as they may have been overloaded For service, help and knowledge there is a Register of BMW Specialists you should find more than one near you most are BMW trained they will have the equipment and Knowledge (one near me specialises in BMW/Porsche) yet is still less than half Dealer labour rates. One of those or an Audio Specialist would be on my list if I couldn't do the job myself. Good Luck Dave

      Amplifier replacement.

      Thank you Dave for the welcome and the reply. The original unit, i believe, was the next stereo up from the base unit, not anything flasher than that. BMW are about as much use as a chocolate teapot and can't/won't tell me what i need without me booking it in with them for them to look and diagnose any issues. My nearest BMW dealer is 30+ miles away and i really don't have the time or enthusiasm to make the trip for them to sell me all the OEM equipment that was removed last time the same fault happened. The issue is the well documented (and ignored by BMW) problem of water entering the boot and sills due to a design flaw, short of silicone sealing all the rear light fittings and drilling holes into my boot floor to drain the water, the issue will continue. Once i figure out what Amp i can replace this one with, i will be looking at jacking up the Amp or creating a unit to sit it in to keep it out of any standing water. Thanks again Dave.

      Amplifier replacement.

      Hi Danny Welcome to the Forum I thought the Amp would be Harmen Becker or Harman Kardon may be Bowers & Wilkins (High end stuff) if it was OEM ? The concern I would have is why the fuses were really, well fused to do that to 40 amp fuses isn't good news. I would have an Audio Specialist look at it if you can't sort it yourself. Take a look at www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your model the check the Audio section to see what should be there. Then look at what to fix or change Dave

      Amplifier replacement.

      Hi All I have a BMW 428i F33 2014 model. The audio amplifiers has been replaced. I bought the car second hand, after less than 3 days the audio amplifier popped and it was replaced by the garage i bought the car from (at no cost to me). However it has blown again. All sounds, both audio system and the normal bings and bongs have all stopped. I have taken the unit out of the boot and discovered it has been replaced with an Audison Bit Ten Signal Interface Processor bit drive and a Hertz Mille ML Power 5 5 Channel Amplifier. It is clearly the Hertz unit that has fried. Both 40amp fuses are welded in place and the unit stinks of burnt electronics. The Audison unit still gets power and appears fine. My question is, do i need to replace the Hertz unit with the same unit again? They are just over £600 for a new one, or can i use any 5 channel 900w amplifier? ( i know next to nothing about car stereos) Has anyone else had the same or similar issue? I don't want a mega pounding, super maxed out stereo, i just want the car to bing and bong again and be able to listen to Radio X on my 7 minute drive to work! I may possibly have included some pictures below? Thanks for your expertise and guidance 1000012573.heic 1000012574.heic 1000012575.heic 1000012576.heic
