Thank you.

If you have bench tool to connect Vag-Com and go to adaptation ch 91 :
Immo off = 1
Immo on = 4

Hello, all I try my file ,but when i go into instrument cluster to me write what : Engine ecu are blocked .
How this need understand ? I immo off ,but car dont start.

[Shmortz]

your immo off is correct, is there error 'engine start blocked by immobiliser' in engine ECU, if not engine must start without a problem, if no error and no starting, there is other problem...
... if engine startt is blocked by immo it must start for one second...

[DjRomeoR]

Thank you for repley in engine ecu are 2 errors: ABS ecu can comunication, Engine ecu disabled.
I writed immo of my file ,when I try start car for one second car on and off , and after what nothink . After what i turn off key wait 2-3sec and try again
start car but same for 1sec on and after what nothink :/

[Shmortz]

hm, post DTC numbers here...
did someone change the pump on that engine?

[DjRomeoR]

Yes pump customer say what change and after what he dont saw car runing :)))) But i check number of ecu A6 2.5TDI 114KW.

ecu faults code: 463A
4689
05A2
Instrument faults : 0303
0232
0522

Thank you for help

[Shmortz]

EDIT:

05A2 say that fuel level in fuel pump housing is low, check fuel level or fuel transfer pump... in tank

and what is that engine code, what year, thread is A4 2004 EDC15VM+, now you write that it is A6 114KW which is 1994-1997year?

[DjRomeoR]

sorry my fault my car A6 2.5TDI mechanical gear, 2004year 114KW , engine code: AYM

And i cheked fuel all ok ,I put in tank 10L .

[Shmortz]

if fuel injection pump VP44 is changed, must be paired with engine ECU, because it have immo function, this is easy if you have VAG-COM or VCDS...

[DjRomeoR]

VCDS i dont have .
Yes it's VP44 and was changed , but i think only i can in ECU immo off and all will be ok cat start.
If it's was changed other car need synchronize with ECU ?
And if i buy VCDS how i can synch... VP44?

[yugo45]

On this car Immo offf does not work if pump was replaced.
You much adopt pump to car.

Immobilizer III Injection Pump Swapping - Ross-Tech Wiki (http://wiki.ross-tech.com/wiki/index.php/Immobilizer_III_Injection_Pump_Swapping)

[DjRomeoR]

So to me need pin code and with VCDS rewrite?
Sorry for stupidity.. but i have old pin car code 7664 and this code need rewrite in ECU with VCDS?

If I buy Vag Can Comander 5.5 + pin reader > can I do with him this car?

[Shmortz]

you need only VCDS or vag-com, I think simple KKL interface and vag-com 409.1 version will be enough to make it work, pin code from your ECU dump is 7664

here is procedure:

Injection Pump Swapping


Prerequisites:
? The NEW Injection Pump is installed in the car.
? Battery voltage at least 12.5 V.
? Make sure to have the Immobilizer PIN, for the Engine Control Unit (ECU).

[Select]
[01 - Engine]

[Login - 11]
? 4-digit PIN
? The PIN needs to be entered as 5-digit number. For example, if your PIN is 1234, enter 01234. in this case 07664
[Save]
[Do it!]

[Adaptation - 10]
Enter 050 in "Channel Number".
[Read]
? 4-digit PIN
? The PIN needs to be entered as 5-digit number. For example, if your PIN is 1234, enter 01234.
[Done, Go Back]
[Close Controller, Go Back - 06]

? Switch OFF the ignition and let the car sit for ~1 minute, then switch ON the ignition again.
? Start the Engine to verify the adaptation was successful.


GOOD LUCK!

Dont need any pin rewriting only need rewrite my file immo of
and from dashboard take off green immo coil wiring and car start's.

Thank you all for help.
