Golf 7 RCD330 (280b) - 5F error U101400 Apr 1, 2022 17:25:31 GMT

I've recently bought a RCD330 for my Mk7 Gti which had the very limited MIB1 installed.

After Installing the unit I'm impressed but have various issues which I believe are coded related, but I have limited experience in coding.

My unit came with the latest software 5532 so ruling out firmware updates etc.

I've long coded 5F

02 73 00 00 FF 00 00 00 00 55 00 01 01 0D 00 00 2F 01 00 C4 00 00 01 00 02

But have the following error

5F Multimedia

System description: MU-G--CN

Software number: 5GD035280B

Software version: 5532

Hardware number: 5GD035280A

Hardware version: 541

Serial number: VWZZZ4R5302594

ODX name: EV_MUGlb4CGen25TPWR

ODX version: 001001

Long coding: 02730000FF00000000550001010D00002F0100C40000010002

Trouble codes:

U101400 - Control module incorrectly coded

Hi Don,

I’m not sure of the old MIB coding or how to get it? Any ideas? Is it worth putting it back in?

As for the protection there is no security on the new radio and the car accepts it without issue so I believe it’s been hacked.

Thanks
Steve

Steve: So here's the thing: if your count the number of digits in the long-code string on your "radio" (it's called a "MIB") - you will find that it has 50 x digits.

This means that the MIB has 25 x Bytes - and this also means that the MIB has 25 x 8 = 200 different software switches, each of which can be the cause of your "incorrectly coded" error message.

Plus, your MIB also has somewhere around 1,100 separate adaptation channels, again also each of which could be the cause of the error.

So, - simply posting-up the error message from the MIB isn't really of much help in solving an "incorrectly coded" fault in a module.

The correct method that you need to use in this type of fault is to make a back-up of the old and the new modules. Then, you should compare the long code string values AND if the error isn't fixed, also compare the settings on EACH of the adaptation channels for both units.

Yes, it's a tedious process when done manually, but alas this is what's needed with these retrofit projects

whataboutthis: le4dsoldier if you have a pre 2024 VAG motor that is supported and you have the Pro or Ultimate license you can code Adaptions and long Coding but after 2024 SFD2 STOPS YOU. SFD Can be unlocked but basic plan only allows you to use OCA Nov 21, 2024 16:52:53 GMT

whataboutthis: fliew you need to share more info, car year have you coded in obd11 or vcds etc there is no magic button to revert to factory setting you have to undo all your changes manually in Adaptions and Long Coding you can copy/paste if you have backup Nov 21, 2024 16:54:18 GMT
