What to look out for
Costly issue
Check for oil leaks around valve covers, sump and gaskets.
AL4 Automatic Gearbox Valve Body Solenoid Failure
The ZF/PSA AL4 4-speed automatic fitted to EW10-engined 307s is known for solenoid and valve body failures causing harsh or delayed gear changes, slipping between ratios, and failure to select certain gears. The fault is worsened by infrequent fluid changes; PSA initially listed the fluid as lifetime but extended service intervals are documented as the primary failure driver. Valve body replacement or rebuild resolves the fault; full gearbox replacement is rarely necessary if caught early.
What you would notice
Costly issue
Press firmly on both front carpets and lift the mats to feel for damp.
BSI water ingress from blocked scuttle drains (footwell flooding, electrical chaos)
The 307's scuttle and windscreen-base drains block with leaves, so rainwater backs up and floods the front footwells and reaches the BSI body-computer and fuse box, which are poorly sealed on pre-2005 cars. Corrosion then causes wild electrical faults: dead wipers, central-locking and dash-warning gremlins, and sometimes a total electrical shutdown. Wet carpets are the tell-tale sign.
What you would notice
Costly issue
Inspect the inner edges of the rear tyres for feathering or bald strips.
Rear torsion-beam axle bearing wear
Like the 206, the 307's rear torsion-beam axle wears its internal bearings, giving a knock over bumps, a vague rear end and uneven rear-tyre wear as the geometry drifts. It usually needs a reconditioned or replacement beam rather than just bearings. It is one of the most common WOF-time surprises on these cars.

Can't confirm for this car
Can't confirm for this car
The EW10 2.0 petrol uses a hydraulic timing belt tensioner. The tensioner loses hydraulic pressure through internal seal wear, reducing belt tension below specification. A slack timing belt causes ignition timing to retard, reducing power and fuel efficiency, and can allow the belt to jump or shed under load. The hydraulic tensioner must be replaced with the belt and all associated pulleys. The Citroën C5 EW10 application carries the same fault.

04DW10 2.0 HDi EGR Valve Fouling and Failure
Can't confirm for this car
Can't confirm for this car
The EGR valve on the DW10 diesel accumulates heavy carbon deposits from exhaust gas recirculation. The valve sticks open or closed, causing excessive black smoke, poor cold-start performance, increased fuel consumption, and intake manifold carbon restriction. Common in stop-start urban driving patterns typical of NZ city use. Cleaning extends valve life; replacement is required once the valve body is scored.

Peugeot 307 buyer questions
Is the Peugeot 307 reliable?
Like any used car, it depends on the specific example and its service history. Across the 8 documented faults for the Peugeot 307, the recurring problem areas are electrical, engine, and suspension. A Peugeot 307 with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.
What are the most common problems with a used Peugeot 307?
We've catalogued 8 known faults for the Peugeot 307, covering electrical, engine, and suspension. All 8 are written out in full on this page, with the symptoms to notice, what to inspect, and typical repair costs for each. Free to read, no account needed.
How much do repairs cost on a Peugeot 307?

Should I get a pre-purchase inspection on a Peugeot 307?
Yes. A Peugeot 307 inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $24.90 far less than the cost of missing one of the faults on this page.
