i tried to use aetool solution, eeprom+flash, but after chaging flash ecu didnt answer and car wont start. With corrected flash ecu only answers in boot mode, but cant write original flash in boot, so used flash programmer. 
And need immo off because of chaging pump vp44, cant adapt.

here is original files

this car don't have immo in the pump, i was owner of the same car. I have changed the pump with second hand ..no immo adaptation..it work for a month..and then change with brand new one no immo adaptation needed

[MeMpHiSj]

no, you wrong. Tell me then why we cant adopt second hand pump? here pump is a part of immo.
this is edc15vm+

[loki954]

no i am not wrong this audi don't have immo in the pump. If you use the same pump there is no need to adapt anything. as i told you : first i change my pump with second hand. it fail ...and the i go to bosch and buy a brand new. same thing plug and play. you are doing something wrong. or the pump is from a newer car that have immo in the pump or a older car that pump dont have CAN.

Check if it is immo3 (ross tech wiki)..immo3 needs adapt fuel pump,its easy few minutes of work,read pin from ecu obd (when readed with smok tool fan works on full speed), then with vcds adapt it in 2 minutes..Done it few times,no need to complicate life with immo off 
If you will install the pump with different numbers or not compatible your pump will be with sound "bzzzzzz" with ignition and you will newer managed to start the car even with immo off
So,dont trust your customer that all pump are the same, you will lost your time as I am with the first audi

it is immo3 but the pump don't have immo in it   I OWNED THE SAME CAR AND CHANGE THE PUMP with second hand and a mouth later with brand new from bosch no immo adaptation. in my experience with vp44 through the years(i change a lot of them). there is two kind one till 2000 with only k-line. This one till 2003/2004(give or take) with CAN and no immo and around 2005(give or take) with immo in it+ CAN. I have change many of them and the are compatible. only have to find the same KIND of pump....immo...no immo...can...k-line..
Post error codes to see what is the problem with your car.

VCDS channel 50 adaptacion with pin code from your dump/ecu eeprom/car will start.

immo 3 ....150hp has not immo into pump (no need adaptation) but 179 HP has immo..!! In that case, make adaptation CH50 instead 32000 put the correct PIN like @zoro1 said. Also, the new pimp must be same like old, same mechanic and electronic part No..in other way will not comunicate with ECu on properly way..so adaptation is not possible.
