Known Peugeot 307 faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01AL4 4-speed automatic gearbox failure (jerky shifts, limp mode)
CriticalCommonTransmission $1,500–$4,500 to fix
The 307's optional AL4 (DPO) 4-speed automatic is a classic PSA weak point: the pressure-regulation solenoids and worn valve body cause harsh or delayed shifts, the Sport/Snow lights flash and the box drops into a limp 'fault' mode. It is very sensitive to fluid condition and the 'sealed for life' myth kills them, as they really need a fluid change around every 60,000km. Repairs mean a valve-body overhaul or replacement box, often more than the car is worth.
Symptoms to notice
Jerky, harsh or delayed gear changes
Sport and Snow lights flashing
'Gearbox faulty' message and limp mode (stuck in one gear)
Flaring revs / slipping between shifts
What to check
On the test drive, from cold and warm, the auto should shift smoothly through all four gears with no jerks, slips or flaring. Watch for the Sport/Snow lights flashing or a gearbox warning. Ask for proof the ATF has been changed (Dexron III, ~every 60,000km); a car with no fluid history is high risk.
Where to look: AL4 automatic transaxle (front of the car, behind the engine)
Ask the seller
“Has the automatic fluid ever been changed, with invoices?”
“Does it ever jerk, slip or go into limp mode?”
“Has the valve body or gearbox been overhauled?”
02DW10 2.0 HDi EGR Valve Fouling and Failure
MajorCommonEngine $490–$980 to fix
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.
Symptoms to notice
Blue or white smoke from exhaust
Difficult cold start or unstable idle
What to check
Check for oil leaks around valve covers, sump and gaskets. Inspect coolant condition and level. Listen for timing chain noise on cold start. The EGR valve on the DW10 diesel accumulates heavy carbon deposits from exhaust ...
