Unfortunately you are quoting Ford's explanation for the code.
VAG (VW/Audi/Skoda/Seat) have a different description.
See: 18048/P1640/005696 - Ross-Tech Wiki

Like I explained in another thread, P1 codes can differ for different manufacturers.

Hi Thank you for interest

I've done full scan of all controllers and there is no any other problems.

Which eeprom content is faulty? 93C56?
Is anybody have a virgin file for this ECU?

I don't wont to do immo off because half electronic stop working after that.

Can I use file from other car get, immo pin and reprogram with VCDS?

Hi I write eeprom and plug ECU today.
That error is clear but there is another one

18020 - Engine Control Module Incorrectly Coded
P1612 - 000 - - - MIL ON
Freeze Frame
RPM: 0 /min
Torque: -98.0 Nm
Speed: 0.0 km/h
Load: 0.0 %
Voltage: 12.92 V
Bin. Bits: 00001100
Bin. Bits: 0
(no units): 0.0

I try do do coding using VCDS 10.6 but it is no possible to change anything in ECU. I can recode any other modules but not ECU

car start no problem, but glow plug warning light flashing.
when I clear that fault light go off till next engine start.

Any idea what is wrong?

Thank you for help

If your desperate to get it through a taxi test, put black tape over the lights till you figure out the problem, they will let it pass as long as they cant see the light, obviously if your desperate till it goes for its taxi test
