Ford Focus
Ford 1.8L Endura-DI turbodiesel 90 hp. Focus I TDi. Also BHDB.
Diesel Too Weak
90 hp diesel in the estate is the worst combination. Loaded it becomes a chore.
Engine Weaknesses 6
The injection pump on the 1.8 TDDi/Endura-DI commonly fails around 150,000 km. The engine starts with increasing difficulty or won't start at all. High-pressure pump failure is typical for older distributor-type injection pumps of this type.
Symptoms: Difficult starting, insufficient pressure build-up, engine stalls shortly after running, unable to restart
The Endura-DI 1.8 TDI with Delphi direct injection pump shows pressure control valve problems that manifest as a flashing glow light and engine cutout. Repair via a Bosch service centre is cheaper than new parts.
Symptoms: Glow indicator flashes during driving; engine suddenly loses power; vehicle will not restart after cutout.
Faulty camshaft position sensors are a known problem on 1.8 TDCi derivatives of the Endura family. The engine cuts out abruptly or won't start. The sensor is awkwardly positioned and exposed to temperature and oil contamination.
Symptoms: Sudden engine cutout while driving, poor cold starting, check engine light
The turbocharger on the 1.8 TDCi Endura is prone to premature wear. Irregular oil change intervals and short trips accelerate coking of the oil feed lines. Power loss sets in gradually.
Symptoms: Declining engine power, whistling, increased oil consumption
The turbocharger wastegate valve on the 1.8L Endura-DI Turbo wears from around 120,000 km. Boost pressure swings and reduced power result. Oil change residue can further impair turbo performance.
Symptoms: Boost pressure swings, reduced power especially under load, possibly a puff of soot when changing up
Like the Endura-D, glow plugs in the Endura-DI rust in and snap when removed. Mainly affects vehicles with low mileages or long periods of inactivity.
Symptoms: Extended cranking at low temperatures; whitish smoke on cold start; rough running for the first few minutes after cold start.
Vehicle Weaknesses 7
Sills and rear wheel arches rust from the inside out. Vehicles from approximately 150,000 km often have widespread corrosion. Always check with a magnet before buying.
Door lower edges and tailgate frequently show early rust spots, particularly at seal contact areas. Water collects in the folds and attacks the metal.
Water enters through a faulty windscreen seal on the passenger side. The pollen filter box can overflow and the passenger footwell carpet becomes wet. Risk of mould.
Rear brake callipers or drum brakes tend to seize, especially after extended periods standing. Brake discs and pads wear unevenly.
Door lock actuators fail frequently; doors lock and unlock sporadically. Plastic window regulator mechanism breaks; window sticks or drops into the door.
Anti-roll bar drop links and control arm bushes wear prematurely. Rear wheel bearings fail without visible play and only become noticeable through noise.
Window regulator motors fail frequently, often due to broken plastic in the drive mechanism. All four doors affected, especially the driver's side. Parts are cheap, but removal is time-consuming.
