How to read ISN BMW Bosch ME 9.2 DME with BDM100 programmer?

This is my personal experience,I have a BMW 318i E46 2005/ Engine N42 Auto,it can’t start once replace the battery and rocker cover gasket. Also Original DME was frie,then i was used BDM100 programmer to solve this issue.

 

Here we are:

Question:

bought a Same serial number used DME. Tried to read dump from old new DME using BDM100 programmer. But I got a error*please check attached images.

 

I have a EWS 3 emulator from “cartools” need to read dump and find the ISN to write it in to EWS emulator!!!

 

 

 

 

 

Solution:

If you ever get a dump, just send the dump to the skilled friend or pay the money and they will virginize it for you, then you sync EWS-dme with ista, INPA, or tool32. No emulators or junk needed.

 

When you get the “ DME FlashVIRGIN” after you read from DME and get a dump,  you use BDM to flash the 1024kb flash, then sync cas-dme with ista (one time procedure for new DME).

 

Steps on how to sync DME-EWS via ISTA? I never tried ISTA for sync:

I would verify the bdm pins and reseat them on the dme, making sure they have good contact.

This tool is kicking our butts.

Once you get it solved,

Off the top of my head, in ISTA go to service functions, engine electronics, look for dme ews, and run the ABL. The ABL will have option for start value reset, or the one time sync for new dme. Run the one time sync function. Sometimes you have to try twice if it doesn’t work first time.

 

PS:

If you get the same question: Please check attached image for DE28F800F3 flash pin data from data sheet. there is a pin for protection called #WP. In the datasheet it said that pin has to be “Logic High” to unblock the lockable blocks. I’m wondering how to make it “logic high”, does that means supply external +5 or +3.3V to Pin 53? Does BDM 100 has any +5V or +3.3V output?

The answer is: You should pull it high with voltage from Vcc pin. 3.6V.

 

So finally, I managed to enable the write function for Flash. It needs to unblock the Write protection via Pin53(I found the test pin which is the same Pin53 behind the pcb, easy to solder) also supply 3.3V from BDM100 adapter. Please check for more clear photos attached. Thanks enabled for helping me out with this issue.

Also I need to follow up regarding EWS 3 reading and sync with DME. Need to learn.
