Second Hand Peugeot 307 Coil Pack

It depends on the engine. The 307's petrol engines — such as the 1.4 and 1.6 eight-valve units — typically use a single coil pack covering all cylinders, while some later or higher-output petrol engines use individual pencil coils, one per cylinder. Diesel engines (HDi) use glow plugs rather than any ignition coil at all, so if your 307 is diesel, a coil pack is not the part you need. Check your engine code on your V5 or a VIN check to confirm which ignition system your exact engine uses before ordering.

The 307 received a facelift in 2005, but coil pack fitment is driven by the engine code rather than the facelift year, so a pre-facelift and post-facelift car running the same engine code can use the same coil pack. However, there were mid-production running changes to ancillary components and mounting arrangements that you cannot confirm from the year alone, so you should give the breaker your full engine code and registration to verify the part matches before buying.

No — trim level (S, SE, XT, XSi, and so on) has no bearing on coil pack fitment whatsoever. What matters is the engine code, which can be shared across all trim levels regardless of badge. Tell the breaker your engine code rather than your trim name, and the cosmetic differences between trims will be irrelevant.

Body style makes no difference to coil pack fitment — the ignition system is determined entirely by the engine, not the shape of the car. A coil pack from a 307 SW estate with the same engine code as your hatchback is mechanically identical for this purpose. Focus on matching the engine code and fuel type, and ignore body style completely.

The 1.6 petrol 307 was offered with several engine codes across its production run, and while some share the same coil pack, others do not — for example, the eight-valve TU5 family generally uses a single coil pack, whereas the sixteen-valve engines may use a different ignition arrangement. Confirm your exact engine code (stamped on the engine block and listed on your V5) and supply it to the breaker, who can then cross-reference the part number and confirm compatibility before you commit to buying.

Physically fitting a replacement coil pack is generally a straightforward job that many competent home mechanics tackle on petrol 307s. However, whether any ECU pairing or immobiliser coding is required in your specific case is something you should confirm with the breaker or a trusted auto-electrician against your registration, as this can vary and is not something that can be stated as fact across all variants.
