BMW E90 320d no start

**rrr500** · 13th May, 2012, 11:32 PM

Hi everyone!
I have a problem again.
I tried to repair a BMW E90 320d 2007 03 month

The owner said: The battery discharged.
They tried to charge the battery,but later when charged up,the car won't start.
The owner towed the car to a BMW dealer.
The dealer tried to update the CAS and DDE software,but no luck.
(I don't know why not tried to resync it first...)

Now,the owner brought the car to me.
I try to resync the CAS-DDE but no luck...
Inpa is no read the DDE.It says: identification error.
I realised the dealer updated the DDE and the CAS and do a fault in the DDE Eeprom and flash.
When i put the key on the fob,and press start/stop button,ignition is OK,but no ECU light,and the information display is shows many errors.
EDC,EGS,Tire detection.etc. fault.

I bought a second hand DDE ecu from a same car.
I put it in,car crank but won't start because the CAS-DDE not in sync.
I tried to sync it each other but no luck.
I read out the fault memory with DIS, and only one fault in the DDE fault memory:
EWS Tampering.

I read here before,if someone update the software to 2012 version (like this) or newer like original,the CAS will disable the sync function via obd...
So, what can i do now?

Can anyone help me to make a virgin DDE or what?

I attach the original CAS and DDE files and the second hand DDE files too.
Please somebody help me!

Regards

I changed the ECU too,to a second hand.. but i can not sync each other...
I need to virginize the DDE,or I don't know.
This is the thing why I am here,and try to ask someone,who is smarter than me.

Nobody can help me?
How can i resync the second-hand DDE and the original CAS?
I have BMW DASH 2.2,INPA,DIS,SSS...etc.
INPA can not read the ecu,because it says: identification error.
I think it is because no identification file of this module.
Any idea?
Regards

you have to match ISN password in the second hand DDE.
Read ISN from CAS and write it to the second hand ECU.
After you can resynch.

Ok i see.
But HOW can is read cas ISN and HOW can i read/write ECU ISN.
Or i ask you another way.
Where can i find ISN in the dump,in the ECU eeprom,and the CAS?

maybe somebody will do it for you, just ask, because as I think you don't have calculator for it. I think INPA can read ISN from DDE or CAS but only read and not all models.

INPA will not read ISN from this car. rrr500 try helping some other people on the forum and you will get a better response.

**rrr500** · 15th May, 2012, 01:26 AM

OK ...
So,can anybody help me to read out the ISN from my CAS,
and program it to the second-hand DDE ecu!?
I attached the files in my first post.
Regards

i think your ecu eeprom is 95640, if so, just put this dump and resync as virgin ecu.

good luck

Hi Mate . Think i have same problem here .

I cannot get diagnostics with the old ecu (Think data is corrupted ...)

Reprogrammed the second ecu with isis as far as i could be allowed ..

Can you give me good dump for 95640 .

I attach dumps from old and second ecu as well .

On the second ecu 95640 are all fffff's and could not get to program it with isis .

Thanks
