Greetings Members

I have a Volvo S40 with blue immobox
Part # 30620876 Immo 3
eeprom 93C66

I have read the eeprom several times, and cleaned the eeprom. when I load on tango, Tag key tool and TM100 key makers it says unknown version. Can you please advise what solution can I use to get the car started. I have attached the Immo Dump, and help will would much appreciated. Thank you in advance

Hi Kiszka

Thank you for your reply, I always read the eeprom the same way when I do the Volvo S40.

The story behind this car is that the battery terminals were swapped(reverse polarity) and the vehicle never started anymore. It flashes a car with a cross on the cluster.

If the immo is dead, can I use another good dump that I read from similar vehicle? Any suggestion of how can i get the vehicle started?

he can use another dump immo only
you will have to do synchro ecu
but you could have killed the immobox, check another immobox

Which tool can I use to do syncro on ecu?
