Common Failure
Timing chain tensioner wear and carbon buildup on intake valves are commonly reported issues, typically occurring between 60,000 and 100,000 miles.
The Ford S-Max 2.0 EcoBoost is a powerful and refined performance petrol engine, but high-mileage examples are prone to specific timing chain and carbon buildup issues. The UNBA and UNBB codes dominate replacement demand due to cumulative wear on timing chain tensioners and intake valve deposits. Rebuilt engines supplied through EnginesMarket include upgraded components addressing these original failure points, backed by a minimum 12-month unlimited-mileage warranty.

Vehicle Value Check
Vehicle Value Check
A typical Ford S-Max 2.0 EcoBoost (Mk2) is currently valued between £8,000 and £18,000 depending on year and condition [THIRD-PARTY]. - Vehicle worth under ~£8,000: repair or a used engine typically makes more sense than a full rebuilt unit. - Vehicle worth ~£8,000-£12,000: evaluate both; reconditioned is viable if keeping the car 2+ years. - Vehicle worth ~£12,000-£18,000: reconditioned/rebuilt usually justifies the premium via warranty and reliability. If your Ford S-Max 2.0 EcoBoost is valued under £8,000, a full rebuilt engine replacement cost risks exceeding the vehicle's value. Evaluate scrap or part-exchange value first.
Our Recommendation
Our Recommendation
If the issue is isolated to timing chain rattle without engine damage, a specialist timing chain service is cost-effective. However, if the chain has jumped or caused internal damage, a reconditioned or rebuilt engine is the most financially sound long-term solution.
