Hello guys,
Tried flashing a map to this ecu  8N0 906 018 H - Audi BAM
Started with MPPS V18 - GENERAL REJECT on 100%
Tried Recovery with Kess v2 - an error occured during the writing - on 100% full
Then went Bootmode with MPPS V18 - Programming Error on 100% ...

HW: 0261206795
SW: 1037360313

Bootmode says following: Micro C167 ID = C5
Eprom ID = FFEFFFFEF
AM29F800BT

Can anyone suggest a solution, what shall I do?

It was straighforward, just resolder, solder and put back the modified map?
Thanks

Hi,
the open source boot tool should be able to switch between BB and BT chips automatically .

I made no difference in Flash driver between bb and bt, the python tool decides which sectors to erase and knows the sector size.
@Marty: should be easy to implement in your suite.

Had this long time ago, not even in boot I was able to flash...  Ended buying new ECU

Question: I saw Ktag can read processor, flash and eeprom... there is some way, let´s say messing with processor to get something like this ?
