Most common problems, symptoms & fixes for the UNCI engine.
Engine UNCI, a 1.5L EcoBoost, commonly faces issues like carbon buildup on intake valves due to direct injection, causing rough idling and reduced performance. Diagnosis involves a smoke test and inspection via a borescope. Prevention includes using high-quality fuel and periodic intake cleaning. Another frequent problem is turbocharger wear, leading to loss of boost pressure; monitor boost levels and listen for unusual noises. Regular oil changes with manufacturer-recommended synthetic oil help prevent turbo damage. Additionally, the dual-mass flywheel may wear prematurely, causing vibrations; replacement is the fix. Timely maintenance and addressing warning signs early ensure engine longevity.
