BMW X5 3.0d ECU problem,please help!

[rrr500]

Hi,

I have a problem with a BMW X5 3.0d ecu.
I tried to search on the net,but i found only this for my problem.
My problem is same like this description:

"Common problem causing engine start failure.
This BMW X5 3.0D engine ECU is a very common problem causing complete non start of the engine, normally the fault will begin as intermittent with the engine not starting every no and again. Sometimes cycling the ignition on and off will correct the problem temporarily.
However the fault always returns with time and gets progressively worse until the engine will not start at all, when the ECU fails you will notice that the engine management light will no longer illuminate on the instrument cluster ***8211; and if you are trying to communicate with the ECU to diagnose the problem you will also notice that it does not communicate with your scanner. "



Now my car won't start.
When i plug diag cable on it,i can read the ecu informations,vin,etc.,but when i try to read live data,this message pop up:
Error_ecu_service_not_supported

I think about maybe the Motorola MPC died,or flash failure...
I don't know.
Please help me to find the problem.

Regards!

when did your car lst time went to BMW dealer?

and you could find a used ecu and swap immo.

This car never went to dealer.
I repaired everything on it.
Before it ruined I succesfully synchronised the EWS-DDE,but after i stop the engine,it won't be start again.

I tried to re-flash with winkfp but the ecu does not answered.

I know that if i buy a second hand ecu that is a solution.
But i would like to repair it,not replace it for another one.
This is why i am here,and i try to ask somebody, who smarter than me.

i aksed you becasue the error you got..its due to an BMW update. I gues you updated the ecu with winkfp right?
do you also have any other flash tools?

No,this car never updated.
I tried it now because i think the software damaged.
BUT i can not update,because the ecu does not answer to Winkfp.
I can read the aif data,vin,etc. with inpa,but no live data,no activation.
If i put ignition on,the cluster temperature guage goes to high (like when no ecu connected,or no software on ecu) and the board drops the messages:
Transmission fault,engine injection system fault,etc.

I know it why,because no can-bus messages from ECU.
BUT WHY?
This is a soft/flash problem or the ecu's motorola MPC died?
That is the question.

I have galetto,but galetto not work on EDC16 just EDC15.
I don't have more flasher tools yet,but i can get one anytime from a friend.
I must know before i get a flasher tool,the ecu died,or just the flash chip ruined?

I think you f.u c k.ed the flash memory.
Post ecu serial numbers so we can get you a Ori. to flash back.
If you are lucky you could do it via OBD with Mpps, or magpro(kess) galletto 2.

If not..you need to BDM the file (opening the ecu) for this you need Cmd Bytshooter, galetto 2 or BDM100

I don't know why you misunderstand me continously.
I'm not perfect in english,but....

So let's start again.
Here is this BMW X5.
This car is worked fine day-by-day.
And then on a beautiful day,stop working.
The car wont start,and throw the fault messages on the IKE display,like Transmission fault,etc.
Then I plugged the diagnotic tool up to the car,read the fault memory,and it shows: EWS manipulation.
I cleared it,and then do a re-sync. I switched off the ignition,then switched on,and car started fine.
After i switched off ignition,i tried to start the car again,but no luck because the ike showed the error messages again,temp guage went to the high end..
So i put the diagnostic tool again on the car,and i tried to re-flash/update the ecu software with winkfp.
But before Winkfp tried to start flashing,it throws error messages:
No communication with ecu.
Then i switched back to inpa,and tried to read ecu's fault memory.
But it shows only a fault message:
error_ecu_service_not_supported

BUT i can read vin,and other data from ecu,just no live data,no fault memory,and no activation menu.
Because when i tried to select any of them,it throws that fault message.

So not me f.cked the flash.It f.cked itself,because its a common problem on this ecu.
Now i just wanted to ask someone,who smarter than me,what can i do,which part bad in ecu.
The flash or the processor.......?
Because i think i have a hardware problem,not software. (i think)
I have ori dump for it,just don't have tool to upload it yet.

Bosch code:
0 281 011 414
DDE 7 800 131

Edit:
This fault messages on IKE display like: Transmission,injection system,etc showed up every time when i turn igniton on and the car won't start.
But when not show fault messages,i can read ecu fine,EWS-DDE sync work fine,and car starts.
This fault is came up random,but now stayed on.
So not me broke the flash..

[ominimicu]

Ok i get it. I dunno, but if the MCU was bad, you could have done anything not even connect to see VIN. So i d go for the flash

Yes,our thoughts slowly came closer to each other
So that was my original question.
If MCU is bad,can i connect to the ecu or not?
Or what happened if just the flash broken?
Can i read ecu data,like vin,bmw part number,manufacturing date,etc?

Can i re-flash or update with some tool,if the flash dump broken?
Or just directly on BDM or possible on k-line?
Because Winkfp can't do it,because it throws the communication error.

If MCU is damaged for sure the ECU won't boot and you can't do anything software related. Not connecting, not reading or writing.
If the flash is damaged you can always find an original to flash back.

[ominimicu]

in order to tell you what tool will doit via OBD, i need to know exactly what ecu does your car mount

The ecu looks like this,but my ecu numbers on label is:

0 281 011 414
DDE 7 800 131

I see.
And if MCU just partially damaged,or it just have cold soldering problem,can it work partially?
I mean,the ecu can boot,can i read identification data,but MCU not controls the flash correctly and the software not running?
Because this fault cames randomly time by time and every time getting worst,but now stay on.
So before this fault stays on,i can start car,read ecu fine...
This is why i think on hardware problem,like MCU partially died,or cold soldering,etc..
Like on my first post.
That site is talking about,it is a common problem on this ecu..
Here it again(but i don't want to advertise here someone's business):

What I would personally do is heat the PCB but about MCU better use infrared

[ominimicu]

It must be failin ginternally, but i dont think the MCU...Open it mate..let s see what is wrong inside.
with it opened, you can press the MCU down , while someone cranks th engine. i did that with a bad soldered flash and worked.
