2016 C7 A6 MM issues/ 5F Module

I have been living a nightmare in regard to my MMI/5F module in my A6. Over a period of time the sound was in and out with a crackling noise. Then the sound wouldn't work at all. A few months ago I was getting some work done on my vehicle and was quoted $4,000 for miscellaneous things, including a new 5F module. I took it to the dealer to get work done because it was winter and honestly... after doing a timing chain job, etc. etc. and correcting all of the mishaps by myself on my B8 A4... I needed a break. The whole 5F module though? I was being cheap and wanted to save $1,300 off of the $4,000... I asked the dealer if I got one on my own, 'would you be able to code it for me'? They said yes. I asked for the part number (I trusted them because they were the dealer so I didn't think to look into it) and obtained a 5f module on my own and installed it. Taking it back to the dealer... they could not take off component protection. They gave me an 'outdated part number' they said and couldn't code it. This Audi dealer is connected to a Hyundai dealer in which they also own... I think the techs have no idea what they are doing. Long story short, I obtained another module (exact part number/supersession) and took my vehicle there a total of 4 more times! On my last visit, my regular advisor wasn't there and in the end I was told they couldn't do anything, they tried everything, and charged me another $179.00 hourly shop fee. I was kind of pissed off to be honest... They called me an hour after that and left and left a voicemail, "I talked to the head of my department and they have other ideas, if you would like to bring it in again, we can try again..." I'm never going back to that dealer. That advisor treated me like I was a clueless person. I didn't even respond, the whole ordeal was just suspicious. It's simple in ODIS, the fact that they "couldn't do it", after they tried and tried... strange. I know they technically don't have to, but they told me yes, then had me come back over and over again...After I left the dealer I immediately took it to an independent audi/vw shop and they took the component protection off in 5 minutes. YAY, SOUND! Finally! However, there was an SVM error on there and the navigation and bluetooth still did not not work. I was supposed to bring it back so I could drop it off for longer... but then the world suddenly changed.

On my own I was able to remove the SVM error by inputting a XOR calculation. The other issues... I still need to somehow figure them out. The only way I can think of is to get coding from a 5f module (if someone has more modules I'd love those to) from a vehicle similar to mine. Not a scan, but a FULL backup. Its also possible I messed up the coding somewhere. I misplaced the backup on an SD card. Why can't I get it off of my other module? Well... I didn't think I would need it and I was getting frustrated (before the component protection was taken off) and I took it apart (roughly) to take off the EEPROM chip from the motherboard and solder it on the other module to attempt to bypass the component protection....lol don't judge me, I was at my wits end... I put it back together, miraculously, but its locked up, it won't even recognize that the vehicle is on, as it states "turn on ignition." I would take my vehicle back to the independent shop, but as we all know, they are closed due to the world situation.

Please Help.

Much love and appreciation!

I have no clue, but my Indy shops around here are open for business, have you checked with them, sounds like a mechanic would be essential

I don't have many options in my area. The only legitimate one, that I went to before, is closed right now. I can do almost everything on my car unless it requires a license (like ODIS)... and with coding it could be the smallest thing... you never know. That's why everyone seems to be stumped and "need more time". I wanted to see if anyone has a similar full backup so I can compare it will the module I have installed before i bite the bullet.

How do you do a full backup? What is the procedure? Vagcom?

What is this xor calculation you speak of?
Also your car will automatically get coded via svm and Odis. I would take it back to that shop again they may be able to do it. I could
do it for you As I have Odis. But I’m in Dallas Texas and not sure how the usb over internet thing works yet.
But svm in all
Audi’s 2013 and newer automatically download from
Germany’s VaG server.

Yes. Or if you have something more simple like a OBDeleven you can do it as well, just go to the control module (5F) and just press backup and it will email it to you or save it.

The component protection is off. I can use the radio and the sound works, but the "navigation data" and the bluetooth is "not activated" and I am unable to use them. The independent shop was actually really interested on what the issue was. He said he was a "geek" and wanted to get down to the bottom of it. He said it might something to do with the coding but it could be anything. The only suggestion was is to get the info off of my old 5F module or somehow get the information from another vehicle like mine. I would bring it back but they are not open at the moment... and I took it to the dealer multiple times and they claimed to not even be able to take the component protection off, hence why I went to an independent shop and they were able to take it off in 5 min.

To remove the SVM error you need to modify value of adaptation 'Confirmation of installation change'. Use this math to calculate new value: "original value" XOR C9D2 = "New value". So let's say you have the SVM error. You go to adaption, confirmation of installation change, and you will see a code. So let's say you see 410a. You do the math 410a XOR C9D2 and it will equal to 88d8. You replace 410a with 88d8 and that removes the SVM error. There are online calculators to do the calculation if you need to. So you would just go on one of those XOR calculation websites and enter 410a as one entry and C9D2 as the other entry and press calculate. Then you will get the code you need to enter in 'confirmation of installation change' to remove the error. Hope that makes sense lol.
