The owner of the V70 replaced the key antena and made a new key and had it programmed by volvo. He said the car start for 2 days and then lost programming. Will it help if I test my S70 ecu and immobiliser in his car and hold my key close to his key antena? Is there a way to bypass his immobiliser?

Thanks for the reply. My friend bought a 1998 V70 T5 that wont start. We tested Crank and cam sensor in my S70 and it worked. We tested the wiring to ecu and wiring from coil module. We tested his coil and module in my S70. We even put his immobiliser in my S70 and it started. His car dont get spark...

Hi All, How do i identify my ECU ? On the label there is a large number 3.2 on it. Any help please?
