6. Turbocharger Damage. With a blockage in the exhaust system, you must also consider the health of the turbocharger. When the gas flow is hindered or slowed down, the temperatures can quickly rise. When the problem isn’t resolved promptly, the turbine housing also gets hotter. Left unchecked, the turbocharger becomes damaged.
Make sure you have an in-depth background about turbochargers and superchargers if you plan to diagnose or fix P0238 yourself.. A Closer Look at the Boost Pressure Sensor. The boost sensor is a feedback signal giving the ECM/PCM information on manifold pressure for the purpose of preventing over-boost and to add data for the fuel injection and timing algorithms during boost.In this guide, I discuss each of these common 2.0 EcoBoost engine problems, symptoms, fixes, and reliability. Ford 2.0 EcoBoost Common Problems. Some of the most common Ford 2.0 EcoBoost engine problems include: Coolant Intrusion; Cracked Exhaust Manifold; Turbo/Boost Control Solenoid Failure; Low-Pressure Fuel Pump Failure (LPFP) Carbon Build-up

I'd suggest it's the exhaust side of the turbo you should be checking, along with the VNT vanes. Not sure how easy it is to access on the Mondeo but one possibility is that the vanes got stuck closed and overboosted the turbo. You should get a warning light and fault code appear if that was happening though so that's not a definite. It suffered failures of the electronics and sensors as well as the control module and, in some cases, failure of the mechanical parts including clutch-packs. Symptoms include harsh shifting, a loss of drive, noises and, as you’ve noted, failure to select some gears. XUPNW0.
