Hi,
So when driving today I went through a deep puddle (might just be a coincidence) and the coil light started flashing and I lost all turbo. The car drives fine, its just got no turbo, revs normally so not in limp mode. When you start the car it takes about 30-45 seconds for the coil light to come on (whether driving or idling) and for that time the turbo works fine, no smoking or anything. Did a fault scan when I got home

Before clearing the codes it also had code 9127 Actuator for Turbocharger 1 P00AF 00 [237] - Stuck
I have looked on Ross Tech for 9127 and 7934 but they do not show anything. Any ideas? is it time for a new turbo?
