Ford Fiesta ST 200
147 kW top version of the 1.6L EcoBoost — 18 hp and 50 Nm more than the standard ST, shorter final drive (4.07 vs 3.82) and more direct steering. Limited Edition with only 500 examples for the 40th Fiesta anniversary in 2016. Overboost briefly releases an additional 15 hp and 30 Nm, peak torque 290 Nm. Structurally identical to the JTJA block, same coolant sensor weakness in the early JA8. The higher boost pressure demands meticulous oil change discipline and consistent turbo cool-down periods.
500 Examples, a Legend
Noticeably better than the standard ST, but no quantum leap — the value lies in the feeling: shorter gearing, more direct steering, the knowledge of its rarity. 0–100 in 6.7 seconds, top speed 230 km/h. Whoever finds one buys it — and keeps it.
Engine Weaknesses 6
Fragments of the clutch pressure plate can be ejected and strike engine components, causing smoke and fire in the engine bay. 1.0/1.5/1.6 EcoBoost with manual gearbox affected.
Symptoms: Smoke development, sudden power loss, in extreme cases engine bay fire.
With the missing coolant warning (Recall 17S09), the engine can overheat without warning. The cylinder head cracks on the Fiesta ST even after a shorter overheating episode due to its high-performance design.
Symptoms: White smoke from exhaust, coolant loss, power drop, engine seizure.
The oil feed line to the turbocharger is prone to leaks. Oil starvation causes bearing damage in the turbo. Typical failure pattern: shaft seal failed, oil enters the intercooler.
Symptoms: Blue smoke on acceleration; oil film in intake tract or intercooler; increased oil consumption; power loss at higher revs.
Ford recalled approximately 56,000 vehicles with the 1.6 EcoBoost (2010–2014). The missing coolant level warning allowed engine operation with insufficient coolant, causing cylinder head cracks. Retrofit: sensor plus software update.
Symptoms: No warning on coolant loss, engine overheats unnoticed, white smoke, power loss, in worst case irreparable engine damage
The 1.6 EcoBoost (Focus, Kuga) suffered piston ring fractures and cylinder bore scoring, in some cases under 110,000 km. The downsized design places high stress on components; the cause is often a combination of overheating and oil starvation.
Symptoms: Zero compression in one cylinder, severe misfiring, no power build-up, engine beyond repair, replacement engine cost £5,500–£7,500
GDI without port wash — carbon deposits on inlet valves. Particularly relevant with ST-typical sporty use combined with frequent short trips.
Symptoms: Hesitation on cold start, power loss, increased consumption.
Vehicle Weaknesses 6
Brake lines and fuel lines corrode faster than comparable competitors. TÜV inspection failures due to brake line corrosion are common. Leaking lines are a safety-critical issue.
Brake lines corrode faster than on comparable competitors. On older vehicles there is a risk of line fractures, which can cause complete brake failure. Check thoroughly before buying.
Rear springs break through corrosion at the lowest coil, similar to the predecessor. Shock absorbers leak prematurely and ride quality deteriorates.
A defective auxiliary heater relay results in inadequate cabin warming. The heater blows little or no warm air in cold temperatures. Solution: relay replacement per TSI 70/2010.
Window regulator mechanisms fail and the glass refuses to move or sticks. Steering column stalk (indicators/wipers) responds unreliably or fails completely.
Worn driveshafts create vibrations when accelerating and cornering. Common on vehicles over 100,000 km. Driveshaft bearings and CV boots wear prematurely.
