Edc17C46 car wont start after flash

[carmageddon]

kess dont make full backup...as first you MUST to make backup with ktag, i have full flash from frf but need to compare with full flash from ktag....then you must read it and place here the readout.

Full backup is only possible using KTAG But you always make risk if you're using clone tools :P

here is my backup from ktag https://files.fm/f/uxnvm3qxr

it was 9981

and micro and eeprom read separately https://files.fm/f/dz56zxh6p

here is my backup from ktag https://files.fm/f/uxnvm3qxr

it was 9981

and micro and eeprom read separately https://files.fm/f/dz56zxh6p

write this two files with ktag without touching nothing on it and test

[al70]

i assume he read with kess and bootloader module which read tricore ok

[remix1992]

i do it now.

[remix1992]

should i write it with restore function or with micro and eeprom seperatly?

when i do this with restore function it says incorrupt backup file.

when i write this seperatly it goes.

[carmageddon]

write simply separately, not as restore

car doesn't start

vcds says : old women (2)-001.jpgold women (2)-002.jpgold women (2)-003.jpgold women (2)-003.jpg

then i have flashed it with a original frf file . ( FL_03L906018HH_9981.frf) with vcp 5.5

but car doesnt run.

my old neighbor (owner) and I are already despairing


I paid €250 to a company yesterday and still nothing works :/

Actually I just wanted to help her to save the workshop costs because of the defective Adblue system (workshop wants 2500 €)


is it not possible to reset the control unit to factory settings and then teach it with vcds?

before i was at the ecu with ktag and kess. there were no other errors apart from the scr errors

I read the dash too
maybe that will help... : sharan service mode.JPG

You'd bricked you ECU Find other same ECU and clone it

[immoneard]

Possible when you open ECU you rip off some components , it happens many times . Try to find same Board and compare it.

Just don't panic. Try what the other forum members said and don't spend even more money.
It is possible that you've damaged the ecu by opening it.
I personally would buy the exactly same ecu (with same engine year, same everything), and would try to read it by obd, and try it just as it is. If the engine starts for just a second and gives a little bit of life, I would do a immo off and try it again. The vin doesn't match but at least the engine is running.

But I never had this problem before. This is just what I personally would do in your situation. I hope you get away with it and please never do this again. If it's your own car it's your thing, but this way you've killed a foreign car and spend senseless money.

In case I'm convinced that my bdm backup from the old one is okay, I would open the new ecu, make a new backup and flash the original ecu backup to it. This way you clone the old one and it's like nothing happened.

Whatever you do don't do this, it does not work that way with your ECU, it is not clonable that way!

I bet, since you dont have experince, that you damaged your ecu while opening it, buy new one with same hw number, open it CAREFULLY , read it and post here

[carmageddon]

at this point i think that you damage ecu while opening because the files are ok

[bobolin4o]

Of course he damage the ECU...
Now he have only errors about injectors!
