P0352 on Peugeot by model: symptoms, diagnosis and fix
The wasted-spark coil pack on the 206's small petrol engines (1.1 KFV, 1.4 KFW and related TU units) is a frequent failure item: one of the two internal coils breaks down, dropping spark on a paired set of cylinders (1/4 or 2/3). Owners report intermittent misfire, rough running, the engine cutting out and refusing to restart until it cools, and the management light flickering. Forum consensus also warns that cheap aftermarket replacement packs often fail repeatedly or seat poorly, causing the fault to return.
Common Symptoms
- Misfire on two cylinders, rough idle
- Intermittent stalling or cutting out, restarts after cooling
- Engine management light flickering or on
- Hesitation and loss of power under acceleration
- Hard or failed starting in damp weather
How to Fix
Replace the coil pack — OEM-quality (Sagem/Valeo/Bosch) units are strongly recommended over cheap aftermarket packs — along with spark plugs if worn. The job is a straightforward DIY or sub-one-hour shop task on these engines.

Frequently asked questions
What does P0352 mean on a Peugeot?
P0352 stands for "Ignition Coil B Primary/Secondary Circuit Malfunction." This is an ignition/engine code. Each ignition coil takes the car's low battery voltage and steps it up into the high-voltage spark that fires a spark plug. P0352 means the engine computer detected a problem in the primary or secondary circuit of ignition coil 'B' — it isn't getting the proper electrical signal back when the coil is commanded to fire. This often causes a misfire, rough running, hesitation or reduced power, and if left unaddressed can lead to unburned fuel damaging the catalytic converter. On Peugeot it is documented across 1 model: 206.
What are the most common causes of P0352?
The most common causes of P0352 are: Failed ignition coil 'B', Damaged wiring or corroded connector at the coil, Open or short in the coil primary/secondary circuit, Worn or fouled spark plug increasing coil stress, Poor power or ground supply to the coil, Faulty ignition control circuit/driver in the ECM (less common). The specific cause varies by vehicle.
How much does it cost to fix P0352 on a Peugeot?
Published repair estimates on Peugeot range from $80 to $250 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
