Hi so my volvo V40 2004 over night just suddenly started throwing like 10 codes,(comes back after erasing) and i think the ecu is toast.

so now i replaced the Ecu, Immo, And key chip. And it dosent start, it just acts as if theres no power on the batteri.

-if i switch to the old immobilizer it cranks all the way but no start.

is it nessecary to replace ignition switch.

i did this on a bmw once, and it was enough to swap ecu, immo, and chip
