I have a m52b28 MS41.0 (1 429 373) ECU.

Partial/full READS are working perfectly each time.

Writes are working according to the flashing tool, but INPA still has "Number of SG-Progs" as the same number than before the flash.
Also the EWS is still giving an error message, even though I flashed a partial file with deactivated EWS.

I have a lab power supply an do the flashing on the bench, my connections are the following:
- Pin 60 - 14V
- Pin 26 - 14V
- Pin 28 - 14V
- Pin 49 - 14V
- Pin 88 - K-Line from MaxDiag Adapter

I tried multiple times, even with different flashers but always get the same result. I would be very happy if you could help me.

that seems to be an ecu version that is not flashable. If it doesnt say index xx on the siemens label, then its not flashable.

Thank you for your reply, but Are you sure it's not flashable?
This is my ECU:

Why I think it could be flashable:
- on the openms41 website, the part numer is not among those deemed "unflashable". https://ibb.co/B6jvnWm
- the board has the 28f200 FLASH chip https://ibb.co/xXz8XK8

If it is confirmed that it is non-flashable, what can be done?
Can the flash be written after unsoldering the component?

Best regards

1429373 is flashable.

Number of programs will stay the same as long as you aren't doing a WinKFP flash with AIF updating.

What EWS DTC number are you receiving? and what is byte 8 of your partial?
