my engine light came on with "turbocharger underboost error". did some research and found that diverter valve is most likely the cause. i got the old one replaced (the seal was torn) and can feel the difference so i think i did the install correctly. it was pretty easy repair in fact. now i understand that engine light could stay on for a while but will clear itself after a while if the problem is resolved. it has been over 2 weeks, dayly driving, the light is still on. does it need to be turned off manually?
