I own Jeep J8 2010 2.8 CRD. I'M facing a technical issue. Once i drive the car for 10 to 30 minutes the check engine light come on and car stop accelerating. By switching the ignition key off and on the car gose back in normal and drive for another 5 to 10 minutes and issue show again. Which I figure that Ecu goes in limp mode and once reset the Ecu or the car ignition key everything goes back to normal. The car Ecu is showing the code of P0234 turbocharger overboost condition and P0299 Turbocharger underboost. New turbocharger with electric actuator control units replaced. New MAF replaced , New Boost pressure sensor replaced. Full leak test done.
