So i swapped my engine 96 AHU 90bhp tdi with an AFN 110bhp tdi. swapped ecu aswell thinking the immobilizer was just in the clocks but it must still communicate with the ecu as im getting the immobilizer flashing light. After a bit of research i think if i find the white immobilizer box under the dash and swap it with the AFN one then i will also have to use the AFN barrel, locks etc, using the AFN key.

Will this work or am i goin to have to get a recode?

Thanks in advance
