Stay tuned! - Авто та транспорт
I’m new to bmw and I’ve got a 56 plate 520d se touring and I have the same issue with mine so many thanks for doing this video… please more 5 series how to fix/replace/troubleshooting videos…. Like/sub
No problem at all. More than happy to help. Anything you want to see, just let me know and I will try and post as much as I can. 👍
Do i need to replace it or I can just remove the module and leave the wires disconnected? I dont need a bluetooth
I have a 2005 model BMW e60 vehicle, there is a malfunction like this, I wonder what happened to this TCU (Getriebe-Steugerät- TEL/ULF/ULF-SBX)
Fehler 1.397 Bluetooth-Taste
Was your AUX working beforehand? If not, did replacing the MULF2 bring it back? I have a 2010 E60 and my MULF2 module was COMPLETELY crusted over… I fiber looped it out and oddly enough my BT started working… I don’t know how removing the BT makes it START working (maybe because the rest of the wires are connected)
Hi, I don’t have a highly specced car so only the standard mulf ‘low’ Bluetooth without sos etc and the standard aux in jack socket. My second e60 has both TCU and Mulf which both control the Bluetooth. Maybe your TCU handles your Bluetooth and the mulf is handling the audio. (Usb equipped cars use the mulf2 unit.) just guessing as I don’t know exactly your spec or factory order. Hope that helps.
@@FuelledLife thank you!!!! If I get a MULF2 from eBay, do I need to match any numbers? Code it? Or can I just plug and play?
@@akura2 just find the same part from around the same time (preferably the same part number.) plug and play. 👍
Hi just checked my boot and there Isn’t any wiring that looks similar to yours was hoping I’d find a Bluetooth module I could code in I have a 2008 e61 530D SE , is it possible to somehow retrofit Bluetooth to my system I have the old CCC like yours I have cables there but definately not what you have plugged into your module any help be great
Thanks
Hi Jason, you would need to run the harness from the fuse box etc around the car, add the module and then code it in. I would recommend just buying a andream carplay unit. It’s modern and works way better for calls 👍
@@FuelledLife hi sir, I have a 07 plate 520d without the Bluetooth module. just wanted to ask that if I replace the stock idrive unit, with the andream unit will it work and give notifications like the idrive unit about the car??
Pls reply it will be of great help..
@@RahulJaiswal-ug1ql happy to help! 👍 it works over the top of iDrive so you gain Bluetooth and apple CarPlay. When your car chimes or has a fault or information is stored, you will see it come up on your dash and hear it. You then simply hold down the menu button and switch back to the old iDrive system and view the message. Does that make sense?
@@FuelledLife oh, thanks. So it means that the idrive will remain in place and continue running, and this andream unit will be an additional upgrade to the car infotainment system. I hope the music sound quality and Bluetooth calls quality/clarity is good enough to hear and talk.
@@RahulJaiswal-ug1ql that’s right, spot on. I personally never had any issues but I guess it’s subjective.
My mulf2 module has corroded from the connectors, so when i replace it do i need the code it and change all the wiring?
No coding required.
Just replace any pins that are corroded or clean them with contact cleaner. 👍 cheers for watching
@@FuelledLife i will let you know how i get on when i clean all the corosion of with contact cleaner, also the codes/numbers on the mulf2 module, do i have to make sure its exactly the same codes/number when i replace the module
I hope my question makes sense. Thanks in advance
I hope this helps anyone with their issue, let me know below if you have any questions. Give me a shout! 👍
Please do a video on key fob not working properly comfort access and the one you can easily switch for a new battery….. many thanks
please help :D did you have to recode your new MULF2 or can i replace mulf2 for mulf2 as a plug and play? :D mine blew up (not a water issue for me) but hoping i can just swap with another one E60 2006 :)
Hi Legless, it was a straight swap. You shouldn’t need to code another MULF2 from a similar car. It worked perfectly!
@@FuelledLife THANKYOU SO MUCH!!! haha i hate having something not working even if i rarely use it :D thanks for taking the time to respond to an old video :) Like and sub from me :)
@@legless00 your very welcome! Thanks for watching 👍 legend!
Before replacing the module, did your USB port and aux worked?
Hi Luis, my car doesn’t have that option fitted. My symptoms were no phone selection and my voice commands button would work but the car wouldn’t speak back to me or respond when pressed.
My usb/aux also don't work. Bluetooth doesn't even toggle in iDrive. Mechanic said the MULF module for my model ties into aux/usb which explains why I don't have either one. They want 1500 to complete the repair. I'll just do it myself for that. 2008 535xi.
@@_Charrizard_ same problem, aux, usb and Bluetooth. Is the problem same?
@@_Charrizard_ mulf 2
Does the new unit need coding or is it a straight swap?
Straight swap Darren. 👍
@@FuelledLife cheers.
Hi, on E61 where is it located
Hi Jovan, in the boot underneath the floor panel and spare wheel cover,
