Good day People, I hope somebody can help me. I have a reception problem with my MIB2 unit. Things important to know: -I have retrofitted a MIB2 but tested it with the MIB1 Module and also there the same problem. -I have checked the aerial amplifier in the back of the car, made sure connections are ok and checked if it was soldered to the rear windshield. -I have checked the connection in the back of the MIB2 multiple times. -Already tried changing long coding byte 12 Dab Antenna to activated, no difference. -When I am in open field I do have DAB signal, very very low. sometimes it picks up a station for a few seconds. Attached are screenshots from my car with live data and faults scan. Here's my question: I am almost convinced that or my cable from unit to aerial amplifier or the aerial amplifier itself is broken, Are there people who have the same opinion or am I missing something like coding or something else? Thanks very much for your reply!     |

24 DF 11011111
DAB all happens in the lower nibble of Byte 10 (i.e. Bits 0-3). I note that the current setting in the 5F module is for EU Band III (which is Bit 1). Not sure if this is correct in Europe (please confirm) - down here we use EU Band III-N (which is Bit 1) Here's the OBD11 screen for the DAB Band selection:  On my DAB MMI (same as MIB), Byte 12 is set to zero However, given the results for DAB signal strength on your pics, I suspect the problem is not coding - but rather either wiring, or equipment malfunction. Here's a diagram of how the aerial wiring changes when DAB in added. Not done this retrofit myself, but worth checking the wiring first before you condemn the amplifier IMO.  Don |

Hi Don, That is confirmed, that is the correct Band to use here. Just to be sure; I have changed nothing on the aerial setup, I see a lot people who change the AM/FM to AM/FM/DAB Aerial. I did not do that because my setup original factory is Left top 5G6.035.577B and Right top is 5G6.035.577 (pics attached) So I did not replace the aerial module, neither did I pulled a new cable to the front because I thought it was not necessary Can you confirm this or do I have to change anything? Also, When I look at your provided diagram it says L1 and L2 is added to the party, does this mean L1 is the black wire going to the DAB connection (black) on the (Top, Back) of the MIB and L2 is a positive terminal (the second cable coming from the aerial module R108 from the back)? When this I correct, can you tell me where L2 is going in the MIB2? If it is indeed a positive, there must be some volts on one of the two connections on R108, so the I can measure this. I then need a way to figure out how to tell if the DAB cable itself is not broken. Greetings Ramon    |

I then need a way to figure out how to tell if the DAB cable itself is not broken. Greetings Ramon Ramon: As I said - I've not done this retrofit, but I read the wiring diagram that I posted earlier to mean that the r108 unit for DAB has 2 x cable connections. Here's a picture showing the difference between the the non-DAB and DAB amplifier/filter units:  Notice the 5G6.035.577B unit has 2 x connectors If your car has 5G6.035.577B already fitted (I'm surprised because VW are known to pare-back everything to bare essentials), then I'm betting (guessing, really) that the second connector on the DAB style r108 on your car is missing because there would have been no socket on the old MIB unit to connect this cable. The new MIB does of course have the DAB fakra connector for this cable. Please check my hypothesis on your car - because if I'm correct, it would explain the numbers in screenshots on your first post. And if you do confirm my suspicion, read HERE for details of the extra cable that will be needed. Yes, the black wire in my wiring diagram has the term "schirm" - which is the shield for the extra cable. Yes, also - my understanding is that the aerial amplifiers (they are really "impedance transformers") do have a DC power supply. They use an operating voltage of 8.5 volts. Take care because these units are very sensitive to this DC voltage - if higher voltages are applied, the electronics in these units will be destroyed.

Hi Don, I attached the pics of my Unit and the back of the unit. This was the original unit which was in my car. If I am correct, this one has also a Dab connection at the top (black) and there was also a fakra connector connected to it. Just for my clarification (as you already notice, I am a noob) 1. The Aerial 5G6.035.77B has two connections, 1 goes to the black DAB connector on the unit, 1 goes to (I think) the FM2 connection at the back of the unit in white, which is a duo connector with the FM1/AM connection at the back of the unit? I ask this because I need to know where the Aerial is getting it’s 8.5 Volts from? Is it getting 8.5 Volts from the fakra connector of the MIB2 unit? 2. When I can confirm 8.5V on the side of the connector at the aerial module, then I assume that my cable is not the problem, more likely the aerial module. 3. When I do not get 8.5 Volts with a multimeter the my cable is the problem. I want to thank you for your great explaining, It’s better to understand, rather then have answers which I don’t know how to translate in the problem I am having. Great!    |

^^^^ Ramon: hmm...... OK - if the aerial Amplifier was factory fitted with 2 x cables connected - then my basic understanding of your situation is incorrect.
Throughout our discourse, I have been assuming that your original MIB unit did NOT have DAB capabilities. That's why I expressed my surprise that VW had factory fitted a 5G6.035.577B amplifier when 5G6.035.577 would have sufficed. And that's why it didn't make sense that there were 2 x cables connected - because the old MIB wouldn't have the thing that you call the "black connector" (because it didn't have DAB capabilities).
Please advise

When I do not get 8.5 Volts with a multimeter the my cable is the problem. Ramon: yes - that's a good approach IMO. Short answer to your question about 8.5 V is that I don't know for sure - the VW wiring diagram for the amplifier isn't specific as to where the DC voltage is applied. But if you agree with my logic - I reckon that we can make an educated guess at the answer! Here's my thinking: The wiring diagram for both DAB and non-DAB amps is again:
There is only one active wire for each cable - so it's reasonable to assume that one of these wires (and less likely - but still possible, both of these wires) is used for both DC supply and for the non- DC aerial signal which will be super-imposed on the DC supply.
As to which of the 2 x "active wires", again I'm not sure- I suggest that you remove the 2 x connectors to the DAB unit from the back of the new MIB unit and CAREFULLY check with a high impedance multi-meter. Make sure that you DON'T short this pin to the outer part of the connector - I'm not sure if the DC supply inside the MIB is short-circuit proof.
If I was a betting person (and I am not), I would guess that the DC supply comes from F1 in my diagram above - because this is the common "active" wire in both DAB and non DAB cases. But I'm guessing!!!
Don

Hi Don, Reporting back with my findings, first I thought I had it solved, but later on it seems it is only getting more interesting. Module 5G6.035.577B: FM2 (Closest to Window) 8.74V DAB 8.83V Module 5G6.035.577: FM/AM 8.78V To be sure that the right cable is in the right place, I have disconnected the Fakra Dab connection at the back of the MIB2 to see the Voltage drop, this way confirmed cable is good and also that it is indeed the right cable. Until now my conclusion was: exchange 5G6.035.577B and happy Dabbing. BUT........ Please look at the image attached with faults 1. When I disconnect the duo connections (in the back) from de "Faulty" Dab aerial 5G6.035.577B then there pops up a new fault in the 5F scan, this way I conclude that there is indeed a working 5G6.035.577B module. And more strange is that the fault code is referring to: "CONNECTION BETWEEN RADIO AND ANTENNA AMPLIFIER 2" (which is greened out when connected again) But the Fault "ANTENNA AMPLIFIER 1 FOR DIGITAL RADIO OPEN CIRCUIT" which I use as a starting reference point of a bad 5G6.035.577B module is totally different as expected. The fault is "CONNECTION BETWEEN RADIO AND ANTENNA AMPLIFIER 2" is referring to my 5G6.035.577B module, but the fault "ANTENNA AMPLIFIER 1 FOR DIGITAL RADIO OPEN CIRCUIT" is talking about something else, not about the Amplifier 2 (5G6.035.577B) Looks like more at coding at this point? Do you have any clues left? Thanks Don.  |

Please advise Don Hi Don, Excuse me! I did not see that post. In my first post I wrote that DAB also did not function with my previous unit (Mib1) Maybe it was better to say that my previous unit also had DAB functionality but also wasn't working in that Unit. (this was what I meant) I totally understand your reaction because you were thinking something else. About the CP, why are you concerned about that? Because it can be a reason why DAB is not working? I assumed that every retrofit MIB2 unit has CP protection enabled in the 5F module when you make a scan. I do not understand that some people with CP can do nothing at all (example: volume change, or no volume at all) and other people like myself can do everything and all is working normal, even coding. Also, because everything is working as it should be I thought this information would not make a difference in approach, but seeing your reaction I think I was/am wrong with that, can you confirm and tell me why? Btw. I bought this unit from somebody who upgraded to the largest screen (MIB 2.5), the unit I have is from his car and he told me it's freed from his VIN and told me when I wanted to do NAV updates I had to go to a dealer to bind it to my VIN first. Maybe that is the reason everything is working right but only remains CP protection in the CAN and 5F module? Thanks!! Greetings Ramon |

Greetings Ramon Ramon: No need to ask to be excused - One of the most difficult aspects when helping folk on these forums is understanding the situation! It's often the biggest reason for not succeeding!!
These discussions are invariably a case of "information asymmetry": the person seeking help ALWAYS knows more about environment than the person trying to help - my question was an attempt to re-balance the knowledge gap (being MY knowledge deficiency)
OK - back to the MIB. I'm always wary of hacked hex5F modules because there is no way of knowing how the hack was done (it can vary greatly). Active CP on any module (note: the Gateway module @ address hexq9 has CP error because it is the master module for the CP interrogation process) is usually a serious complication and it shouldn't be ignored. But I guess we have to rely on the seller's assertion that DAB was working on the MIB before the sale to you. I don't normally like do this, but I will proceed by ignoring the CP/SVM and incorrect coding DTCs in your screenshot
Of more interest (to me) is your statement that you had the same problem with the DAB function with your old "MIB1" unit fitted. IF THIS IS CORRECT, then logic would suggest that there is a problem with the peripheral equipment for the DAB function. If I ignore CP, I suggest this because I understand that you have installed 2 x independent MIB units to the same aerial equipment and in both cases the same fault symptoms have resulted!!
I do like your process for confirming the DC voltage on the amplifiers - but in truth, this only confirms that the amplifier circuits are receiving a power supply. Your testing results say nothing else about the ability of the DAB amplifier to filter the digital radio signal and provide a usable waveform to either of the MIBs.
So - with the caveat that I have limited knowledge of the complete environment in your case, I tend to cling to that well proven diagnostic principle called "Occum's razor" : when fault finding, the simplest of competing theories is to be preferred to the more complex.

@adrianvw Hi Adrian, Thanks for making that clear! Yes, I do know what “hacked” means. But not how it was related to my unit. I was assuming that it was in a “free” phase, not binded to any VIN and because of that I could make full use of the unit, but the scan will still say CP active. Good thing I did not wanted a nav update because I think the dealers wouldn’t have helped me. I am a total noob and read a LOT of info on the forums but this specific info I did not found. (because obvious I was not looking for it The reason I want DAB so bad is because I listen to Radio 538, which has a poor FM reception where I live but on the DAB frequency it’s perfect.

donHi Don, Totally understand what you are saying! When you say it like this, I don't understand why I did not saw this because it is very logical. It is correct that I also had the same problem with the MIB1 unit, which is DAB capable and also with this unit I had problems receiving DAB signal. I will find another DAB module and will replace this, when It is not working, I will replace the cable. I will report back here when I have it replaced and share the outcome. The long coding 5F MIB1 (original) is attached at this post. Here is the text translation: 02737001FF00000011111201000800001F0105D401000100D7 Thanks for clearing up the CP fault in the CAN, did not understand where it was coming from since it has nothing to do with the 5F.

Hi Don, I have replaced the aerial module and DAB is working now!! Thanks very much for your help, it is really appreciated!! Attached some pics of the broken module. You can clearly see in the module why it is not working anymore (at the connector side, white residu) Greetings Ramon     |

That “white residue” is water damage, I can’t see it’s broken tho, water residue is conductive so it can make it look like a short circuit (electrically) although your fault report states that it’s open circuit which is a bit confusing,

Instead of creating another post, I've decided to ask here. I'm looking to adding DAB Retrofit Kit to my 2017 US Golf, but I'm not sure if my unit supports it. Can anybody tell me if it does? Back of the unit (sorry for the bad picture, didn't want to pull out all the cables for a better one), Top of the unit (serial....) |

grbac : here's a picture that you might find interesting - it's the rear of an OEM MIB:
Your picture of the back of your MIB looks a tad different - but it does appear to have the DAB aerial plug - which appears to have the DAB coax wire already connected!
The coax wire suggests (emphasis on "suggests") that this car has been built with DAB capabilities. If so, it's odd that DAB hasn't been enabled!! What's the back story for this car?
What country ? Post-up the long-code string for this MIB

Hi DV52,
the car it's been exported from US to EU, it's a Composition Media with SiriusXM (don't know how to remove it from the options like you can with AM band). I already tried enabling it with OBD11, Byte 10, Bits 00010010, but the DAB option doesn't appear after the "Hold On/Offbutton for 10 seconds" with the "Incorrectly coded" fault.

grbac: Hmm......... OK. If you are attempting to make a "Yankee" MIB operate on a DAB transmission band - I'm not surprised that it ain't working!!. The ONLY digital radio that has been approved in USA is what they call "HD radio" (officially known as NRSC-5) - which is entirely different to DAB/DAB+. Technically, it can be argued that the US form of digital radio is more superior - but this distinction is academic because the majority of the rest-of-the world has adopted various versions of DAB! So, MIB units that are installed in North America Region (NAR) vehicles that use a MQB platform build have a Component label that is something like MU-E--US. However, the component label for MIB units that are installed in EU cars is something like MU-S--ER. I'm not sure of the exact difference between the 2 x MIBs - but DAB capability is one of the distinguishing features!!
There is absolutely NO reason why NAR MIBs should have the DAB function because the underlying radio protocol isn't used in USA - alas.
The fact that the long-code string on NAR MIBs still have DAB software-switches doesn't matter - I suspect that this is a relic of the MIB standard operating system)!

So what you're saying, in sort terms is that I can't enable/retrofit DAB unless I swap the glovebox unit to an european one?

grbac : Yes, at the very least - you will need a new (non NAR) MIB unit to get DAB - which must have the DAB plug as shown in my diagram. However, I'm also not sure about the DAB aerial/amplifier set-up (see my earlier posts above about this item). Because I live way down in the Southern hemisphere, I don't get to see many NAR model cars (in fact I don't see ANY) - but I can't imagine that a NAR Golf will have a factory fitted DAB arial set-up as installed in EU model cars. Here's a copy of my wiring diagram from my earlier post My hunch is that the NAR set-up is like the diagram on the left (i.e. "Only models with no digital radio") because these cars don't use DAB. I suggest that you pull-out the existing MIB from this car - does it have the DAB plug? My strong suspicion is that you will also need to swap the "Left aerial module" (R108) with a DAB version of this aerial. Also, I suspect that you will need to install a "Digital radio aerial" (R183) and the second coaxial cable that terminates between R108 and J794 (which is the DAB plug shown in my first reply to your post) Finally, you should also understand that the MIB has Component Protection. CP means that when a new MIB is retrofitted into a car - it must be "authorized" to the VIN or else a CP error will be generated which will mute ALL audio. To officially delete CP errors, you will need to take the car to a dealer. It is possible to buy a hacked MIB unit to avoid the CP error effect (most hacked MIBs still have CP errors - but they don't mute the sound). Don

Don, us radios are satellite
Also depends on how it’s “hacked” but sometimes the reason everything is enabled on them is because you can’t use tools like vcds or obdeleven on the unit, and you can never upgrade the firmware without problems, but it’s been a while since I’ve played with any of this
