The Ford Focus has been one of the most popular used cars in Ireland for two decades and this generation is no different. Sharp handling, strong economy and a massive parts network make it an attractive buy. But the 1.5 TDCi has two specific issues every buyer needs to understand before committing — one under the bonnet, one in the gearbox tunnel.
Overview
The 2015 facelift Focus brought a cleaner exterior, updated infotainment and the new 1.5-litre TDCi engine replacing the older 1.6. It sits in a competitive segment alongside the VW Golf and Skoda Octavia but typically undercuts both on price while offering comparable equipment. For Irish buyers it represents excellent value — provided you know what to look for.
Engine & Gearbox
The 1.5 TDCi produces 95hp or 120hp depending on spec. The 120hp version is the better choice for motorway commuting — more relaxed at cruise and no less economical. The vast majority of Irish examples are paired with a 6-speed manual, which is the only gearbox to consider. Some higher-spec models came with Ford's PowerShift dual-clutch automatic — a dry-clutch unit with a poor reliability record on this engine. Shuddering at low speed, hesitation on pull-away and expensive control module failures are well documented. Stick firmly to the manual.
Known Faults
Degas bottle failure is the headline issue on this generation. The plastic coolant expansion bottle is prone to cracking, causing rapid coolant loss. When it fails without warning and the driver misses the temperature gauge climbing, the result can be catastrophic engine overheating. Replacements are inexpensive but the consequences of ignoring the failure are not. This is the first thing you check at any viewing.
Coolant system leaks more broadly are a pattern on this engine — not just the degas bottle. Coolant pipes and hoses should be inspected carefully on any higher-mileage example. Any sign of dried white or brown residue around hose connections warrants investigation before purchase.
PowerShift transmission failures have been well documented across multiple Ford models using the dry-clutch dual-clutch unit. Shuddering and hesitation at low speed are the early symptoms. Left unaddressed, the clutch pack and transmission control module can fail — expensive repairs that often exceed the car's value on older examples. Only consider a PowerShift example if the transmission has been recently serviced and you have documentation to prove it.
SYNC 2 infotainment freezing and screen blanking is a common complaint on 2015–2016 models. Not a mechanical issue but worth checking thoroughly on the test drive — a replacement unit is an avoidable cost.
What to Check on Inspection
Open the bonnet immediately and inspect the degas bottle. Look for cracks, discolouration or any signs of leaking around the cap and base. Check the coolant level and condition — it should be clean and at the correct mark. Any sign of brown sludge in the coolant suggests a head gasket concern.
If the car is a PowerShift automatic, walk away unless you have full transmission service documentation. Test drive a manual example instead.
On the test drive, run the SYNC infotainment through its paces — navigation, radio, Bluetooth. Screen freezing or blanking under use is common on early examples and worth flagging before you agree a price.
Ask for evidence of cam belt and water pump replacement. Most Irish specialists recommend changing both together every 5 years or 120,000km on this engine.
"Check the degas bottle before you do anything else. It is a five-minute check that could save you an engine."
NCT Watch Points
Rear suspension bushings and emissions failures from a clogged DPF are the most common NCT failure points on this generation of Focus. The DPF issue is most common on cars used mainly for short urban journeys — ask about typical usage before viewing. Front lower arm bushings are also worth checking on higher-mileage examples.
Running Costs
Road tax is approximately €200–€210 per year depending on the specific engine variant. Real-world fuel economy is 50–55 MPG on a mixed cycle for the manual. Parts availability is excellent and independent garage labour rates are very competitive on the Focus — one of the cheaper diesels to maintain in this class.
What to Pay in Ireland
Budget between €9,500 and €14,000 depending on spec, mileage and year. ST-Line and Titanium models with full service history push toward the upper end. Avoid anything priced significantly below market on a manual — the degas bottle history will usually be the reason.
Verdict
Buy — manual only, with service history. The Focus 1.5 TDCi is a genuinely good used car when the coolant system has been maintained and the gearbox is the six-speed manual. The degas bottle is a known quantity and a cheap fix when caught early. What you want to avoid is a neglected example or anything with a PowerShift badge. Get the manual, check the coolant, and this is one of the better used buys in Ireland at this price point.
Frequently Asked Questions
The plastic coolant expansion bottle is prone to cracking on this generation, causing rapid coolant loss. If missed, the engine can overheat catastrophically. Inspect the bottle carefully at every viewing — it is the most important check on this car.
No — avoid the PowerShift on the 1.5 TDCi. The dry-clutch unit is prone to shuddering, hesitation and expensive control module failure. The 6-speed manual is the only safe choice on this engine.
The manual version with a full service history is a solid used buy. The degas bottle and coolant system are the main concerns — both are manageable if caught early. Avoid any example with a history of overheating or a neglected coolant system.
Between €9,500 and €14,000 depending on spec, mileage and year. ST-Line and Titanium models with full service history command the upper end. Be cautious of anything priced well below market.
