Low Power - Help with codes

[Juke42690]

Hi all, 

Looking for some assistance. Recently encountered an issue with my 17 plate juke tekna where the power drops off in gears 4, 5 & 6 when trying to reach above 45mph - eventually reaches 60-70mph but have to feather the acceleration pedal and when foot is slammed to the ground and going uphill the revs start to drop and the car slows down as if there’s no power

first instance the amber engine management light came on but didn’t have the OBD2 reader to scan and check. Car has since had a major service and fault cleared but has returned with no engine management light

OBD2 reader showing fault P0380(glow plug/heater circuit A) and P1453(manufacturer control)

assuming manufacturer control is limp mode? But surely any fault that drops the car into limp mode would throw up other lights on the dash

attached pics of OBD2 codes

any help would be appreciated, cheers
