Ford 1.5L Duratorq TDCi 75/95 hp. Used in B-Max and EcoSport II.

• !! Recall Camshaft Sprocket Material Fatigue (16B42)

  Ford recalled approximately 8,400 vehicles (production October 2014 to April 2015) because the camshaft sprocket can fracture due to material fatigue and damage the engine.

• !! EGR Cooler Crack with Coolant Ingestion from 120,000 km

  The EGR cooler develops cracks under extreme thermal cycling. Coolant enters the intake tract and forms black foam in the expansion tank. In the worst case a hydraulic lock results.

  Symptoms: Black or oily foam in the coolant expansion tank, coolant loss with no external leak, white exhaust smoke, tendency to overheat.

• !! DPF Issues from Short-Trip Driving from 80,000 km

  The 1.5 TDCi frequently suffers from DPF clogging. Regeneration temperature is not reached on short trips, resulting in failed regeneration cycles and fuel dilution of the oil. Widely reported as the most common warranty complaint.

  Symptoms: Check engine light, power loss, raised oil level, DPF warning lamp

+ 3 more engine weaknesses + vehicle weaknesses

Award-winning three-cylinder turbo with wet timing belt and integrated exhaust manifold in the head. Light and efficient, but oil quality and change intervals are critical for longevity. Chain-driven from mid-2018.

• !! Wet Timing Belt Dissolves in Wrong or Old Oil from 100,000 km

  The oil-bath timing belt degrades with incorrect oil type or overdue change intervals. Rubber fragments block the oil strainer and endanger the oil pump and connecting-rod bearings.

  Symptoms: Unusual noises from engine bay, engine warning light, in the worst case engine seizure from oil pressure loss.

• !! Degas Hose at Coolant Expansion Tank Fractures from 80,000 km

  The plastic fitting on the turbo coolant hose at the expansion tank becomes brittle and fractures. Rapid coolant loss can overheat the engine in minutes and cause irreparable damage.

  Symptoms: Visible coolant loss, steam rising from engine bay, temperature warning. Coolant level drops rapidly.

• !! Head Gasket Failure from Thermal Stress from 120,000 km

  The integrated exhaust manifold in the cylinder head generates extreme heat. Insufficient cooling (e.g. after degas hose failure) can blow the head gasket.

  Symptoms: White exhaust smoke, oil-milk in expansion tank, coolant loss without visible external leak, power loss.

Ford 1.4L Duratec 16V (Sigma) 90 hp. Used in B-Max 2012-2017.

• !! Timing Belt — Interference Engine with No Warning from 140,000 km

  Sigma/Duratec 16V engines are interference engines with a timing belt. Ford quotes 150,000 km service interval; workshops recommend 100,000 km. A skipped or snapped belt causes total engine destruction.

  Symptoms: No prior warning — sudden engine stall and engine damage if belt snaps without replacement

• !! Ignition Coil Failure — Misfires from 120,000 km

  The pencil ignition coils in the Sigma/Duratec 16V family fail at around 100,000–140,000 km. Problems appear mainly at 1,500–2,500 rpm under load. Aftermarket coils (BERU ZS350) are considered more reliable.

  Symptoms: Hesitation and torque loss in the mid-rev range, fault code P030x, rough engine

• !! Worn Valve Stem Seals from 120,000 km

  The 1.4 Duratec SFDB shows typical oil consumption at higher mileages due to age-hardened valve stem seals. Blue smoke after overrun phases and slight oil consumption are typical signs.

  Symptoms: Blue smoke on cold start or after prolonged overrun, slightly increased oil consumption with no visible leak

Ford 1.6L Duratec Ti-VCT 120 hp (88 kW). Used in Focus III, Focus II facelift and B-Max.

• !! VVT Phaser Failed — Cold Start Rattle from 100,000 km

  The 1.6 Ti-VCT has excessively narrow oil drillings in the cylinder head (pre-2007 production). The phaser becomes oil-starved and rattles on cold start. Ford improved the design from spring 2007; older engines are more frequently affected.

  Symptoms: Diesel-like rattling on cold start that disappears after warm-up; power loss under hard acceleration

• !! Ignition Coil Failed — Misfire from 120,000 km

  The Sigma/Ti-VCT pencil coils fail at around 100,000–140,000 km. Typical failure at 1,500–2,500 rpm under load. Aftermarket coils (BERU) are considered more reliable than cheap own-brand alternatives.

  Symptoms: Hesitation and power loss in the mid rev range, fault code P030x on OBD, rough running

• !! VCT Camshaft Phaser Contaminated from 80,000 km

  The 1.6 Ti-VCT suffers from contamination of the non-replaceable VCT filter in the cylinder head. Metal particles block the filter and restrict oil flow to the VCT solenoids, causing hesitation especially when cold.

  Symptoms: Hesitation and power loss on cold start, rough idle below 2,000 rpm, engine warning light
