Ford Focus DAW
Weaknesses, engine ratings and buying advice
The Focus I (1998–2004, chassis DAW/DBW) was Ford’s quantum leap from the forgettable Escort to the most dynamic compact of its era. Legendary chassis, progressive styling — and rust is the nemesis.
Most important: sills and rear wheel arches rust from the inside out. Pre-2000 cars are almost universally affected; Ford improved cavity sealing from 2000. Sill repair costs €400–1,200.
Engine choice: The FYDA (1.6L Zetec-SE, 100 PS) is the most reliable — timing chain, 250,000+ km with basic maintenance. The HXDA (1.8L Zetec-E, 115 PS) has more torque. Diesel: F9DA (1.8 TDCi, 100 PS) is solid but turbo oil line can coke. Avoid the BHDB (1.8 TDDi) — expensive Bosch VP30 pump.
Electrics: Central locking actuators fail (€150). Window regulator clips break (€80–150). Water ingress through pollen filter seal.
Test-drive: Underside torch check (rust?), heater on max (blower?), all windows, cold diesel start (smoke?), central locking.
2026 market: From €1,500–4,000. ST170 €7,000–12,000. RS €15,000–28,000.
Insider pick: FYDA 1.6 Zetec manual, 2001–2003 — post cavity-sealing fix, simplest engine, cheapest entry to real driving fun.

Ford 1.8L Duratorq TDCi (common rail) 100 hp (74 kW) and 115 hp (85 kW). Focus I and II. Long-lived with regular maintenance — DPF issues at higher mileage.
- !! Injector seal: "Black Death" failure from 120,000 km
The copper sealing washers at the injector seat fail under pressure and heat. Combustion gases blow past the injector and bake black, tar-like carbon onto the injector boss. Seized injectors require specialist tools for removal; the cylinder head sealing face can be damaged.
Symptoms: Black deposits around injectors, diesel smell, rough running, cylinder pressure loss - !! Turbocharger failure from 150,000 km
Turbocharger damage from oil starvation due to blocked oil supply passages, or from soot ingress via leaking injector seals. Repair costs are significant, as the sump and cooler must also be cleaned in addition to the turbo.
Symptoms: Whistling or grinding from the turbo area, severe power loss, oil entering the intake tract, blue exhaust smoke - !! High-pressure pump failure from 180,000 km
The high-pressure pump on the 1.8 TDCi frequently fails between 150,000 and 220,000 km. Metal wear particles contaminate the fuel system and injectors, often requiring the entire common-rail system to be renewed.
Symptoms: Engine cuts out suddenly, flashing glow plug light, poor throttle response, engine will not restart, blue smoke

Ford 1.4L Zetec-SE 16V 75 hp used in Focus I hatchback 1999-2005.
- !! Timing belt — engine damage on failure from 120,000 km
The Zetec-SE is an interference engine: if the timing belt snaps, pistons meet valves. Ford's specified change interval is 150,000 km; 100,000 km is the recommended practice. Replace all idlers and the tensioner at the same time.
Symptoms: Sudden engine shutdown without warning, loud bang on failure, severe engine damage - !! Individual ignition coil failure — misfires from 110,000 km
Individual ignition coils (pencil coils) of the Zetec-SE/Sigma block fail at higher mileages. Symptoms often appear at 1,500–2,500 rpm under load. BERU aftermarket coils are more reliable than some OEM options.
Symptoms: Stumbling and torque loss at 1,500–2,500 rpm, engine control fault code P030x, rough idle - !! VCT filter clogged from 90,000 km
The 1.4 Zetec-SE with variable cam timing suffers from contamination of the non-replaceable integrated VCT filter in the cylinder head. Metal particles from the valvetrain block the filter, causing cold-start misfiring.
Symptoms: Judder and power loss on cold start, engine warning light, rough running until operating temperature
+ 3 more engine weaknesses + vehicle weaknesses

Symptoms: Sudden engine shutdown, power loss after timing belt replacement if incorrectly fitted, loud bang - !! Timing belt tensioner failure from 120,000 km
The timing belt tensioner on the 1.8L Zetec-E can fail before the official replacement interval of 160,000 km. Tensioner wear leads to belt skipping and engine damage. Replace preventatively every 120,000 km or after 9 years.
Symptoms: Rustling/clattering from the timing belt area, power loss, in extreme cases a loud crack as the engine fails - !! Ignition coil failure — misfires from 130,000 km
The twin ignition coil (coil pack) of the Zetec-E is prone to failure at high mileages. Misfires on cylinder 4 (P0304) are frequently the first sign. Replace HT leads and spark plugs at the same time.
Symptoms: Misfires (fault code P030x), rough idle, power drop, fuel smell in the exhaust
+ 3 more engine weaknesses + vehicle weaknesses
2.0L four-cylinder naturally aspirated 1988cc. Duratec HE in the Ford Focus FLH (Mk1) 2001-2005. 170 hp. Base engine of the first Focus generation.
- !! Intake Throttle Plate Problem (Early Build Dates) from 80,000 km
The 2.0L Duratec HE in the late Mondeo MK3/Facelift can still have the early intake manifold type with throttle plate risk. Must be checked on vehicles before 2003.
Symptoms: Rattling from the intake, possible engine damage - !! Increased Oil Consumption from 160,000 km
At mileages above 150,000 km the 2.0 Duratec HE shows increased oil consumption. The engine is fundamentally robust, but valve stem seals and piston rings wear.
Symptoms: Bluish smoke, oil level dropping, oil traces at exhaust - !! Chain Tensioner Wear from 160,000 km
The chain tensioner on the 2.0 Duratec HE in the late Mondeo variant wears prematurely at long oil intervals. Cold-start rattling at 150,000+ km is typical.
Symptoms: Brief rattle on cold start, stops after warm-up
+ 3 more engine weaknesses + vehicle weaknesses
2.0L Duratec Turbo, 215 hp — the original Focus RS and pioneer of the super-hatch genre. Front-wheel drive with a Quaife limited-slip diff: the steering wheel pulls noticeably under full throttle, torque steer is a character trait, not a bug. Above 3,500 rpm the turbo growl swallows the wastegate hiss. Only 4,501 examples built, all in Imperial Blue. Engine is known as tough and modification-friendly — Stage 1 delivers 260+ hp. Driveshafts and turbo oil supply are the main concerns at high mileage. Cam belt every 100,000 km. The car looks better with age, not worse — the design doesn't date. Holds its value well: prices rarely drop below market level.
- !! Timing Belt — Engine Destruction on Snap from 120,000 km
The 1.8 Zetec-E is an interference engine requiring precise timing belt tension. Special tools are needed for correct installation; wrong positioning causes immediate power loss. Replacement every 100,000 km recommended.
Symptoms: Sudden engine cutout, power loss after timing belt change if incorrectly fitted, loud bang - !! Timing Belt Tensioner Premature Wear from 120,000 km
The timing belt tensioner on the 2.0L Zetec-E tends to fail before the recommended replacement interval of 160,000 km. If the tensioner fails, the belt jumps and causes massive valve damage. Preventive replacement every 120,000 km is recommended.
Symptoms: Rattling noise from the timing cover, in the worst case engine failure without warning - !! Ignition Coils Failed — Misfires from 130,000 km
The dual ignition coil (coil pack) on the Zetec-E is prone to failure at high mileages. Misfires on cylinder 4 (P0304) are often the first sign. Replace ignition leads and plugs at the same time.

Holds its value well: prices rarely drop below market level.
- !! Chargecooler Water Pump Fails — Heat Damage Possible from 70,000 km
The electric pump in the water chargecooler fails — coolant boils, charge air gets hot enough to melt spark plugs or damage pistons. Regular functional checks are mandatory.
Symptoms: Noticeable power drop under boost, MIL, in worst case pinging or knocking - !! Chargecooler Hoses and Metal Pipe Corroded from 60,000 km
The metal pipe in the chargecooler circuit inside the wheel arch corrodes and leaks. Original rubber hoses collapse with age. Aluminium replacement parts are significantly more durable but hard to source.
Symptoms: Coolant loss in the chargecooler circuit, damp patches in the wheel arch, power loss from reduced flow - !! Wastegate Sticking — Boost Spikes from 60,000 km
The wastegate actuator on the Garrett GT2560LS sticks after periods of inactivity. Overboost or lack of boost build-up results. Particularly known on vehicles with long periods between use.
Symptoms: Irregular boost build-up, power drop or boost spikes, whistling from the turbo

2.0L Duratec ST 16V naturally aspirated with 127 kW at 7,000 rpm — the first Focus ST, entirely without turbocharging. Equal-length stainless steel headers produce a distinctive, full-bodied resonant exhaust note. 85% of peak torque (196 Nm) available from 2,200 rpm — remarkably broad for a high-revving naturally aspirated unit. Above 5,000 rpm it comes alive, spinning to 7,350 rpm at the limiter. Mechanical bucket tappets instead of hydraulic — valve clearance check every 40,000 km recommended. Long-lived with consistent servicing: owners report over 177,000 km without issues.
- !! Timing Belt — Engine Destruction on Snap from 120,000 km
The 1.8 Zetec-E is an interference engine requiring precise timing belt tension. Special tools are needed for correct installation; wrong positioning causes immediate power loss. Replacement every 100,000 km recommended.
Symptoms: Sudden engine cutout, power loss after timing belt change if incorrectly fitted, loud bang - !! Extremely Thin Piston Rings — Oil Maintenance Critical from 130,000 km
