BMW E90 EWS Tampering ISN MATCH

**JFR-Tuning** · 24th February, 2021, 07:26 PM

I have a E90 in my garage.
I change damaged EDV16C35

I read ISN in cas and DDE
WITH ABRITES AND CGDI
it is Short 4 byte one
I Write Theater DDE ISN in cas
I read it and Looks fine

But i cant Match the STARTWERT DDE WITH CAS3
I have in the DDE EWS tampering
Key is Fine
Kl15 is on

I cant Change Short or Long vin in the DDE

Any idea what is the metter?

Zwo Werks before i do Same on X6 it works fine

Friend. And the old driver starts? Because if so, lose eeprom. And you have the problem. If you have Bdm, it's no problem and why play with programming

A Part of your answer i dont understand
I dont open the new Donner ecu. I have bdm nur them org ecu is death read with success

As on the old controller, the car starts. Then make a copy of the eeprom and that's it. Few minutes of work. Faster than programming and ISN submission

Ok i Must Open the ECU

But for the futeres, where is the problem of this. I Need to understand the Problem for the next ecu change

Clone ECU with BDM tool, copy over all files including eeprom. Then sync EWS-DME with diag tool

Thnx Member,

I have a org ECU with damaged dump in flash
So First way whas this way to clone BDM ( KTAG CLONE)
But it dont work if y use org eeprom and from new used Donner MCU & Flash . By read flash i get error CKS
THIS CAR COME FRIM OTHER GARAGE and they work a Lot off bad

And

I Write i will understand the reason why i can change in Same ecu edc16C35 a few weeks before - Other project- the VIN in ECU and Match ISN with AVDI ( old stand Alone) and now Not

Take lose only eeprom alone. Leave ori in the new driver.

Post OLD and NEW EEPROM (engine ECU) here

thnx m8

what y mean with

ori in the new driver. ?

**elektronik325** · 26th February, 2021, 08:47 AM

Yes. Writte Ori eeprom in the new Ecu. Flash left the Ori from new ecu. Must work

yes i thought the same. I think I do it like this in past. But if you do it it shows in AVDI the old VIN from Donner car. In eeprom I have new vin. I think that’s the reason I can not match

after I put org EEPROM DUMP in new Donner ECU EDC16C35 and Write ISN I get from read org Cas with ISN editor ( It can not do EDC16C35 ) the match will done with AVDI and DTC tampering go away. But car doesn’t start. In ista D it show me again that it is a Donner ECU from other car and will not work. If I read with CGDI AND AVDI I have two different ISN in CAS and DDE.

i get yesterday VVDI2 .

i think with bench connection can read isn in DME and CAS.

BUT NOT WORK ....VVDI2 CAN NOT READ EDC16C35 not on bench not by OBD ~~~~ing tool

so a result..

i post all dumps here for a M8 will help and compare it, but I don’t understand where is the Problem

and I Must Buy Autohex

AVDI , CGDI AND VVDI2 do Not well the Job. All isn reading with them say the same isn in CAS3++ and in DME Edc16C35
but if you will COMPARE start value i got answer different ISN

~~~~ING ....

So for all members here a help for ISN on EDC16CP35 with Cas3 +

The ISN is in EDC16C35 locatet on 3 Pos.
0x0042-43 >>>> CKS is on Pos 0x005E-5F
0x0082-83 >>>> CKS is on Pos 0x009E-9F
0x00C2-C3 >>>> CKS is on Pos 0x00DE-DF

the CKS is also on 3 Pos to calc use
0x0040 to 0x005D
0x0080 to 0x009D
0x00C0 to 0x00DD

COPY each of that Line to ( little program for free )
http://tunya.de/public/res/getsum.html

and y get the CKS for EDC16C35

For Cas ISN is in Pos

0x0002 to 0x0003 >>>> CKS is 0x0004

If you change ECU y have wrong VIN . Solved with WINK FP . The VIN is also in Flash

at last you must make a match for start bit between DDE and Cas with Inpa AVDI or other tools

have Fun and start the Car

thx will be fine
