where is stored HWEL number in KOMBI??? (FSERIES) - ruben_17non - 05-12-2023
hello
just i buy one 6WB kombi of F10 but not work comes from flood car.
Im looking and PCB of signal are "same" as my other kombi of f10 M5, only any connectors and other components are different but not is difficult swap.
i want flash M5 6wa PCB as 6WB is possible?
In 160WT eeprom or in near soic8 have HWEL number or this is in MCU???

Yes HWEL number it's inside MCU.
I attach the reading of an MCU Fxx

You read with vvdiprog?
Have pinout of MCU in pcb?
This mcu can be read but write maybe not?

Desoldered chip, I haven’t pinout for PCB

6wa can be written without problems

I have a pinout. I have backups of delivery speedometers. A programmed speedometer has a software lock. Back then I broke two 6WBs on my project. I won't be sharing the pinout any time soon

You need to identify the MCU type
Search for it in vvdi MCUs
If you are lucky it should be there
Trace the points from mcu legs to nearest pcb soldering points. (If its non bga)
Try to read.
If its ok to handle losses you are good to go, if not, don’t touch it
I understand why some people don’t share these schemes, because it really takes alot of time and effort.
Sometime you work alot and u don’t reach anything, or end up with non profitable or non interesting findings.

Can you replace 35160 if you restore backup of a new 6wb?

Yes!
Is MB91F467D
i found all soldering points PADS.
but MD0,MD1,MD2 are really necesary??, its extrange in my PCB are all in gnd
In my case i buy 6WB from flooder and other broken 6WA of M5, and i want with these two repair 6wb and put in my F26. i not want make profit im personal use
im not sure about pin 70,71,72 in PCB are in GND
