Audi A6 allroad 2002 level control

[Alex789]

Hello.
Audi A6 allroad 2002. Level control unit 4Z7 907 553 E has permanent fault "65535 - Internal Control Module Memory Error". There is MC68HC912D60 0K75F inside.
Has anybody full flash for this unit?
Enclosed is eeprom and seems to be correct.
Thanks.

[Alex789]

Does somebody have such flash?

[tintin2005]

hello my friend

can you tell me where that dump belongs to ?
is it from the xc68hc912 controler? which one ..... the one thats in the uppside or downside?
next to the mc68hc912 in the top side there?s a 8 pin ci TFK28730 that seems to be an external eeprom of the motorola mcu. anybody knows if this is correct? if yes does anybody has a dump for it and wich eeprom it should be?

i would be gratefull.
thanks

[Alex789]

Hello.

Both Motorola CPUs (upside/downside) are used. Each of them contains own internal eeprom (not external). Sorry, I don't have good dumps for these processors.

Regards

[tintin2005]

If you put in both the *** *** 553A and *** *** 553E parts number you get the message:


"dropped on 01/07/2004, please use as replacement"

427 907 553F

So your 553E ill do the same job as the 553A

i know how to repair this unit
contact me on PM

[bgcomp80]

Your PM is full, maybe you can give me a hint on where to start .

[bgcomp80]

There are two MCU`s XC68HC912D60, one on front side and the other on the rear side .

You can repair the suspension module by writing the flash and the eeprom in both MCU`s.

I attached the last software 4Z7 907 553 F .

The module used was 4Z7 907 553 A and now works with 4Z7 907 553 F software and works perfect .

Enjoy .

You need to put +12V to pin 71 in qfp80 processor, then you can operate flash.

Hi,
Does anyone know reason why some of this ecus cause battery drain? :hmmmm:

[maucontacto]

Hi,
I'm new to this forum, but not new to Allroad's...
I've seen several of these controllerd fail with the 65535 memory error code.
And I have a buch of these.
After what I see here, there are a possibility to gove the controller "new" life"?
Can any one confirm this, and maybe even give an old Viking an explanation of the procedure?
Thanks,
-Roy

thanks for the file! great job

[Telectroboy]

Hello guys!
I have the same problem with an Audi AllRoad. I have few tools to read and write even Xprog.
I hope to be able to solve it thanks to your help [Crossing fingers]

Thanks a lot. I'll tell you the result.

:)

[Telectroboy]

Hello Guys!

This is the values of EEPROM I have read with Xprog...
What do you think about that?

The module doesn't work and display 65535 in VAGCOM.

Thanks alot.

I will have to fix an audi a6 suspension control unit 4Z7907553A but I have XC5113c1cfu8 processors


do you have solutions?

[blazeBG]

I have same issues (error in memory) with module 4Z7 907 553 F.
I have "A" module from a friend, it is as mentioned with different microcontrollers.
I ve tested it, but got an error with controll buttons as far as i press some.
Seems like the "A" module is incomplatible with "F" , unless you reprogram it!.

I need files for "F" module, but the link on previous page is down. Can someone share the files again?

EDIT: LINKS WORK, BUT FILE GOT DOWNLOADED AS 4Z7 907 553 F.rar.zip

Solution: Simply delete .zip from the name of the file.

[roy001]

How did this turn out for you?
I have several ECU's to reprogram...
