I have a 2015 dart 1.4 turbo. The car has 203K on it. It’s the wife’s car she was driving down the highway when she said she lost power and the car wouldn’t shift right. I towed it home and got to looking at it. First I noticed that the AOS box is leaking. Next I noticed that the main hose off the air filter housing was loose on the turbo but also noticed that there was oil in the hose. I tightened up the hose and car still does same thing no power. I do have the p2262 code and have found no other air leaks. I read about the wastegate adjustment but wasn’t sure if I should bother seeing as the turbo doesn’t even act like it’s working. Is there anything else I can do? Tests? Checks? Before I take it to the dealer and get a new turbo?
