Lack of power with the engine warning light and P0299 / P0234 on the 1.6 EcoBoost: wastegate solenoidInjection / turbo

Engine / equipment: 1.6 EcoBoost direct injection: Focus, C-Max, Kuga, Fiesta ST, Mondeo and Transit Connect
Period mentioned: 2013–2016
Symptoms: The engine loses power and the engine warning light comes on. The computer stores codes P0234 (turbo overboost), P0245 or P0246 (wastegate solenoid circuit) or P0299 (turbo underboost).
Possible cause described: Ford bulletin 15-0162 (October 2015) for the 1.6 EcoBoost of the Escape, Fiesta ST and Fusion says to check the charge-air-cooler pipes and vacuum lines first; if they are fine, the cause is the solenoid valve that regulates the turbo wastegate, and it is replaced.
Check for the garage: Read the codes. Check that the charge-air-cooler pipes and vacuum lines are not split or loose; if they are fine, test the wastegate solenoid (under the engine) and make sure its hoses are fully fitted before replacing the turbo.
