Coding TCU in E46
 

Hi all

So, I have a little problem...

I have a 2002 e46, and 3 years ago I retrofited OEM Sat Nav with Widescreen, tv, mk3 and harman-kardon. I used a wiring harness from a 2005 E46, and this harness have a 54 pin connector. So far, so god...

Some time ago I started thinking about retrofit bluetooth, but, as the ulf are very expensive, I started looking for an alternative. That's when I realized that a TCU can also work, but not 100% guaranteed. In these respect, I have to thank this forum for all the shared information :thumbup:

I bought a used TCU from ebay: eBay - The UK's Online Marketplace

EVEREST IBUS ECE
Part #:6963758
19-02-2006
SW:28 HW:50


So, I connected this to the car, and it didn't work, not even a small signl... and burned the fuse #7.
After that, I realized that, as the navi wiring was retrofited, the TCU had no power or ground ...
Connections made ​​and...it works. :D

Now the real problem. The coding
I used NCS to change the FA, adding $644 (PREPARATION F MOBILE PHONE W BLUETOOTH), $633 (PREPARATION, MOBILE PHONE, BUSINESS), $640 (PREPARATION F TEL.INSTALLATION UNIVERSAL) and $638 (CAR TELEPHONE PROFESSIONAL), one at a time, and then used Progman to code the module. But in progman only appears, in the retrofit menu, the options TEL/ULF, ULF, Professional TEL and BIT, and nothing about TCU or Telematics.
I tried all settings FA/Option that I remembered, and finally got it to work (FA=633 and Option=ULF/TEL). But with a limitation... I can only pair a phone, and has to be about the time when the Progman just encode the TCU. After that the TCU works well but is not found on other phones, so it is impossible to try to pair again.
To pair another phone I have to remove the FAs, and code ALSZ and AKMB, turn off the car and wait, add again the FAs, encode again the AKMB and ALSZ, and recode using the ULF/TEL Option in Progman.

I tried navcoder to pair but gives error.
And one more thing. The VR in this TCU is in German. I tried to code to english with navcoder but without success.

Some of you have any ideas to code this? and to change the VR? :dunno:

Thanks in advance
And sorry if the text isn't very correct. English is not my native language

I can answer one small part...

The TCU VR language is driven by the language selection that the nav computer is using. So, what language is the nav computer set to?

If your nav computer is not German, then are you using a modified OS that has mapped German to something else?

The MK3 is set to english and spanich. And the current OS i'm using isn't modified. But I will try to update the languages through Navcoder or Progman, maybe that way the TCU can load other language.

Early TCUs were locked to one language.
It is possible that your TCU supports German only, and no other language (regardless as to how you code it)

As for how Progman works with your car... well, that's Progman for you ... :-(

Hope it's not the case:( . I'll try loading the languages

I didn't understand what you want to mean by that... :dunno:

I am not sure what your point was regarding Progman

If you were not happy about how Progman works with your E46, well, I cannot help you with that.

That's not the point. I think you didn't understand my post

What I want is some idea on what the correct way to code the TCU to the car, with Progman, NCS, WinKFP, Navcoder or whatever...so I can pair more then one phone at any time.

You do not need to code the TCU to pair multiple phones. You therefore do not need to use Progman, NCS, WinKFP, NavCoder or anything at all.

The pairing of multiple phones is a standard function built into the TCU, and is not coding relevant

If more than one phone has been paired, and both phones are available and active, then it is a real lottery as to which phone pairs with the TCU when the TCU turns on.

Try it to see what happens

But the problem is that the TCU don't recognize any phone when it was supposed to happen (right after turn the ignition on). When I first connected the TCU to the car, I knew she had to go into pairing mode, but that didn't happen. I only managed to pair a phone, when coded it .
And this is the real problem, because whenever I want to pair a phone, I have to code the TCU, and it's very boring, apart from that, it can only have a phone paired at a time.

Maybe I'm coding it the wrong way... I need ideas...

Try this method for pairing the phone. It is a little different, but from my reading, there may be two methods for TCU pairing, depending on the version of the TCU.
