In this video, we demonstrate how to diagnose error code 126800. The Y77/1 boost pressure positioner for the turbocharger is faulty. We check the boost pressure positioner while the engine is idle and show how it displays its position percentage during rapid throttle changes. Note that no repairs are performed in this video - it only shows how to check the position adjustment of the boost pressure positioner. The diagnostic process was performed using a Launch X431 but can also be done with similar tools like Thinkdiag. To ensure that the boost pressure positioner or boost pressure controller, responsible for the VTG control on the turbocharger, is indeed faulty, follow our step-by-step guide. Follow our guide to better understand your vehicle!
