914 Builders,
I've been going through the final install and have a question about the
wastgate servo. When I switch on the TCU and it cycles the wastegate the
panel lights(red & yellow) both come on the go off as expected but the servo
does this huming sound like it is trying to do something. Is this normal?
thanks for all advice in advance,
craig ellison
