Vehicle goes in to "limp home" following codes set:17705 pressure drop between turbo & throttle :17545 fuel trim system to rich I think if i could find the pressure drop (17705) that might take care of the 17545. i have no external leaks of the pipe work from turbo to throttle body,i was going to look at the many no return valves,and other pipe work next.codes has not set with us wile road testing but set with customer after about 4 -5 days,and i dont think she drives it very hard. The only other symptom we have is engine seems flat after cold start.
