Ford Focus 1.5 TDCi Mk3

The Focus Mk3 uses an electric power-assisted steering rack with an integrated motor and control module. This is a well-documented weak point on 2011-2015 models, though facelift cars from 2014 onwards have a lower failure rate thanks to improved sealing. Failure modes include complete loss of power assistance without warning, intermittent assistance on startup, or the message 'Power Steering Fault Service Required' on the dashboard. Water ingress through the column side of the rack corrodes internal electronics. The EPAS control unit and rack are matched at the factory and cannot be separated, so the entire rack assembly must be replaced. A remanufactured unit costs 600-1,200 euros, with 3-5 hours of labour since the subframe must be partially lowered. Total repair at an independent garage runs 1,200-1,800 euros, rising to 2,500 euros at a Ford dealer with a new OEM rack.

In December 2024, Ford issued a global recall affecting approximately 768,000 diesel vehicles including the Focus 1.5 TDCi, covering production years 2014-2023. The DPF filter material develops hairline cracks over time from repeated regeneration cycles, allowing particulate matter to bypass the filter. This results in failed emissions tests and elevated exhaust particle output. Ford's fix involves a software calibration update and, if necessary, DPF replacement free of charge. Owners who previously paid for DPF replacement can claim reimbursement with proof of payment. Newly installed filters under this recall carry a 10-year or 160,000 km warranty. Verify with your VIN whether this recall has been completed. If you are purchasing a car that has not had this recall done and the DPF is already damaged beyond software repair, replacement costs 800-1,500 euros if done outside the recall programme.

Independent of the recall above, the DPF requires sustained driving at motorway speeds for 15-20 minutes to reach the temperatures needed for passive regeneration. Cars used primarily for short urban trips accumulate soot faster than it can be burned off. Each incomplete active regeneration attempt dumps unburned diesel into the engine oil, raising the oil level and diluting lubrication. Symptoms include the DPF warning light, loss of power, and limp mode. A forced regeneration at a garage costs 100-150 euros. Professional DPF cleaning costs 300-500 euros. A new aftermarket DPF costs 500-800 euros fitted. In severe cases where oil has been heavily diluted, an oil flush and change are also necessary. Check the oil level carefully before purchase: significantly above the maximum mark indicates diesel contamination from failed regeneration cycles.

Ford recall 16B42 covers approximately 8,500 engines with the 1.5 TDCi built between October 2014 and April 2015. The camshaft sprocket can develop cracks, and if it fractures the timing belt loses synchronisation, causing piston-to-valve contact and catastrophic engine damage. The recall repair takes approximately 4 hours and replaces the sprocket and timing belt. This is critical to verify before purchasing any early 1.5 TDCi Focus. If the recall was never performed and the sprocket has already failed, engine replacement costs 3,000-3,500 euros. Even on later production cars not covered by this recall, it is prudent to inspect the sprocket condition when the timing belt is replaced.

The electronically controlled EGR valve accumulates carbon deposits from recirculated exhaust gases. Urban driving and short trips accelerate the problem. Symptoms include rough idle, hesitation on acceleration, increased smoke, and fault codes related to EGR position or intake airflow. Cleaning the EGR valve costs 150-250 euros at a garage. A new valve with programming costs 400-700 euros at an independent specialist. Regular motorway driving at higher RPMs helps keep the valve clearer. Some owners find that cleaning is needed every 40,000-60,000 km in urban-heavy use. The EGR cooler on this engine can also develop internal cracks in rare cases, mixing coolant with the intake air.

The 1.5 TDCi uses either a Mitsubishi TD02H2 or Garrett GTD1244VZ turbocharger depending on power output. Turbo failure is less common than on the older 1.6 TDCi because the oil feed design is improved and the injector seal carbon issue is less pronounced. However, the vacuum-operated wastegate actuator can stick from carbon deposits, particularly on gently driven cars, causing boost pressure faults and limp mode. In some cases, small cracks develop in the vacuum tubing, preventing proper actuator operation. Check all vacuum lines before replacing the turbo. Actual turbo bearing failure is relatively rare and usually caused by oil starvation from neglected maintenance. A replacement turbo fitted at an independent specialist costs 1,200-1,800 euros. At a Ford dealer, expect up to 2,200 euros.

The dual mass flywheel absorbs the torsional vibration of the diesel engine. Typical failure occurs between 130,000-180,000 km depending on driving style. Symptoms include metallic rattling at idle, vibration through the pedals, and difficulty engaging gears smoothly. When replacing the DMF, the clutch disc, pressure plate, and concentric slave cylinder should be replaced simultaneously since the gearbox must be removed anyway. Parts (DMF + clutch kit + CSC) cost 400-700 euros. Labour adds 500-800 euros. Total at an independent garage is 900-1,400 euros; at a Ford dealer, 1,500-1,800 euros. Urban stop-start driving and towing accelerate DMF wear.

If your Focus 1.5 TDCi has the Powershift automatic, it uses the problematic DPS6 dry-clutch dual-clutch transmission. This gearbox has been subject to class-action lawsuits in several countries due to premature clutch wear, input shaft seal leaks contaminating the dry clutches, jerky shifts, and stalling at junctions. Symptoms typically appear between 40,000-80,000 km. Ford has offered some goodwill repairs, but many cars are now outside any warranty or goodwill period. Clutch pack replacement costs 1,200-1,800 euros. If the mechatronic unit is also damaged, costs rise to 2,000-2,500 euros. Manual gearbox models are significantly more reliable. Before buying any Powershift-equipped Focus, test-drive for at least 20 minutes in urban traffic to reveal any jerking or hesitation.

The thermostat housing is made of plastic and can deform over time from heat cycling, developing coolant leaks. If the leak goes unnoticed, coolant loss can lead to overheating. The 1.5 TDCi aluminium head is sensitive to overheating, so even brief temperature spikes can cause damage. The thermostat housing and seal replacement costs 300-600 euros depending on whether the water pump is also replaced at the same time (recommended if the car is over 100,000 km). Regular coolant level checks are essential.
