I'm trying to get my s5 started and I've currently narrowed it down to the coils not getting the 5v trigger they need.

I've replaced ecu and had it fully coded.

Fuel pump primes, fuel gets to the engine.

We're getting 12v to the coils but no 5v when cranking.

The car was in an accident and hasn't started since. Bit I'm now stumped
