The Peugeot 207 replaced the hugely successful 206 and sold well across Europe as an affordable supermini. The 1.4 HDi diesel uses the PSA DV4 engine family, a compact and generally durable unit that delivers excellent fuel economy. With proper maintenance, the engine can exceed 200,000 km without major issues. The main ownership concerns are electrical faults (particularly ECU water damage and power steering failure), turbo wear from oil starvation on neglected examples, and DPF clogging on post-2010 models used for short trips.

Common Problems
Coolant contamination travels via wiring harness into the ECU, corroding internal circuits · more· less
A very common failure on Peugeot 207 models built between 2007 and 2011. Engine coolant can enter the wiring harness and travel via capillary action up to the ECU connector, corroding the terminals inside. Symptoms include anti-pollution fault messages, engine misfires, failure to start, cutting out at idle, and temperature gauge malfunctions. The problem is often initially misdiagnosed as sensor faults (throttle position, coolant temperature, injector circuits) because the corroded ECU produces misleading fault codes, leading to unnecessary sensor replacements before the real cause is identified. ECU repair services cost approximately €250-350. A replacement ECU from a dealer costs €600-800 including coding. Used units require dealer-level diagnostics to match the key coding.
Power steering motor driver board fails, causing progressive then total loss of assistance · more· less
The Peugeot 207 uses an electric power steering system that is known to fail across all engine variants. The failure typically starts intermittently — steering becomes heavy briefly then returns to normal — before progressing to a permanent loss of power assistance. The root cause is a failing driver PCB (printed circuit board) on the power steering motor. Repair by a specialist (replacing the circuit board) costs approximately €120-250. A full replacement unit costs €300-450 at an independent garage. Dealer repair runs €400-600. Peugeot has covered this repair for free on some vehicles — it is worth contacting Peugeot customer care before paying, as goodwill contributions have been granted due to the widespread nature of this defect.
Carbon deposits block the turbo oil feed pipe, starving the turbo bearings of lubrication · more· less
The 1.4 HDi turbo can fail due to oil starvation when carbon deposits block the oil feed pipe. This is less common on the 1.4 than the 1.6 HDi (which has a well-documented epidemic of this issue), but it still occurs on neglected examples. Long oil change intervals allow carbon to build up in the oil, which deposits in the fine gauze filter of the turbo oil feed pipe. Once oil flow is restricted, the turbo bearings overheat and fail. Symptoms include loss of power, excessive exhaust smoke, and whining or grinding noises from the turbo area. A replacement turbo costs approximately €600-1,000 for the part (new or refurbished) plus €200-400 labor. The oil feed pipe should be replaced or cleaned at the same time. Prevention: change oil every 10,000-12,000 km with the correct specification, not the maximum 20,000 km interval Peugeot allows.
Carbon deposits block the EGR valve, causing rough running, loss of power, and anti-pollution faults · more· less
The EGR valve on the 1.4 HDi gradually accumulates carbon deposits, especially on cars used predominantly for short urban trips where the engine never reaches optimal operating temperature. A clogged EGR causes rough idling, hesitation under acceleration, anti-pollution fault messages, and sometimes stalling. Cleaning the EGR valve costs approximately €100-150 at a workshop. If the valve is damaged beyond cleaning, replacement costs €200-500 depending on whether an OEM or aftermarket part is used. Some owners fit EGR blanking plates as a budget fix, though this is not road-legal in many EU countries and will cause MOT/TUV failures.
Diesel particulate filter clogs on cars driven mainly on short urban trips, unable to regenerate · more· less
Peugeot 207 models from late 2010 onwards were fitted with a DPF. The 1.4 HDi engine runs relatively cool, making it particularly difficult for the DPF to reach the temperature needed for regeneration during short trips. If the DPF cannot regenerate, soot accumulates until the engine enters limp mode with a warning light. The DPF also uses Eolys additive fluid stored in a bag under the car — if this bag leaks or runs empty, regeneration cannot occur regardless of driving pattern. Professional DPF cleaning costs €200-400. DPF replacement costs €500-1,000 for the part plus labor. Eolys additive refill costs approximately €150-250 including labor. Pre-2010 models without DPF do not have this issue.
Alternator fails, typically after 100,000-150,000 km, causing battery warning light and electrical issues · more· less
The Peugeot 207 is known for alternator problems, particularly on earlier models (2006-2008). Symptoms include the battery warning light illuminating, electronic devices losing power intermittently, and eventually the engine cutting out as the battery drains completely. Early models (April 2006 to May 2007 production for the 1.4) were subject to a recall for alternator defects. Even outside the recall, alternator replacement is a common repair on higher-mileage examples. A replacement alternator costs €100-200 for the part plus approximately €100-150 labor at an independent garage. Dealer costs are approximately €350-500 total.
Affordable diesel with electrical weak points
The 1.4 HDi engine itself is fundamentally robust and can exceed 200,000 km with regular servicing. The main ownership risks are electrical: ECU water damage, power steering motor failure, and alternator faults are more common than on competitors. Turbo failure from oil starvation is less prevalent on the 1.4 than the 1.6 HDi but still occurs on neglected cars. Post-2010 models add DPF concerns for short-trip drivers. Buy a well-maintained example with documented oil changes and verify there are no warning lights on the dashboard.

Verify completed
Seat heater cable harness fire risk (June 2009 to May 2015 production)
Verify completed
Battery earth cable failure causing engine shutdown (2010-2011 production)
Verify completed
Rear brake hose abrasion from contact with suspension spring
Verify completed
Contact a Peugeot dealer with the VIN to verify all recalls have been completed. The seat heater recall is particularly important as it involves fire risk even when the car is parked.
Warranty Status
Factory warranty (2 years)
Expired on all used 207s
Rust perforation warranty (12 years)
May still apply to 2014 models
All Peugeot 207 models are well outside their original 2-year factory warranty. The 12-year rust perforation warranty may still apply to the newest examples (2014 production). Extended warranty options are available through independent warranty providers but verify coverage for ECU and power steering issues, as these are often excluded as known faults.
