[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.

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

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.

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

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?

[maucontacto]

How did you read this processor???
I can read with UPA but just one of them. I use xprog, etl and rosfar but none of them can comunicate.
