Hi all,
i really need some help with this code P0638
This says its (throttle actuator control range/performance bank 1)
has anyone seen this before ?
can the throttle body be repaired or is it a case of a new one?
if i have to pay for a new one i will but if its not the problem would be one hell of a waste of money?

any help and advice welcome

tried so far
remove throttle body and cleaned it
replace air sensor

all with no joy
