Read your keys do they have a value or logic?(chips inside key can be wipe clean or damage.

Check the ariel around the ignition if it is not power up the coil your key won't send the data.

If data from key is written to a EEPROM where does it go if battery goes dead? IT is still there but your monitor are dead Sence your battery has no power. On a vw key needs be turn to on position for 15 min. I have reprogram keys before to jump start the monitor.

Hi , keys are okk

here are photo from ecu
i can see flash and mpc but i can't see any eepom for readin
I can not see the backpart of this ecu as i think it is conected with board...
I don't know how to read via bdm ...

Any help to start this car ??

try to read via BDM and if eeprom is present, you necessarily will see it.
i think, external eeprom on back side of ECU
connection as standart Bosch EDC16 (first 10pins is used)

ECU has ST95160 on other side of board you can read with BDM ...

Thanks kev

any of you have bdm conection for clone bdm 100
as i can not find any bdm conection for my type of ecu
If anyone can help me with connection and explain me exactly becouse i have never read via bdm

Thanks

have you checked the fuses under the bonnet i had the same problem last month a 20 amp fuse and it was perfect

[kaToo]

yes i have checked ... all is OK
the only problem that i can see is sync IMMO(dashboard) - ECU
I try sync with diagnostic but the ecu is giviming me the outcode all 0000 ... so i could'nt calculate incode to make sync...

All i need is BDM connection using BDM clone... or any help how can i open this ecu in the back side...

Thanks

ALL EDC16 ECU`s HAVE A SAME BDM CONNECTIONS (12PINS CONNECTOR ON BOARD, ONLY FIRST 10 PINS IS USED)

in attached PDF (BDM100 connections for many ECUs,for clone) search connection for EDC16/MED9X
