Hi. I have a Mazda 3 sport 2.2l diesel 2014. I took my Mazda into Mazda coz of power loss. They said oil wasn’t getting into the turbo so I need a new engine and turbo costing £10,500. I paid £7500 a year ago. Please help. Anything I can do. Won’t a carbon clean clean it out? I’m not a car mechanic so I don’t know too much.
