P0302 on Land Rover by model: symptoms, diagnosis and fix
The Rover KV6 2.5L V6 engine used in the Freelander is notorious for head gasket failure. The V6 design uses two head gaskets (front and rear banks) and the rear bank is particularly prone to failure. The aluminum heads warp from overheating, and the original gaskets deteriorate. Head gasket failure causes coolant and oil mixing, overheating, and eventual engine destruction if not addressed. This is the single most well-known Freelander issue.
Common Symptoms
- Overheating especially in traffic
- White smoke from exhaust
- Milky residue under oil filler cap
- Coolant loss with no visible leak
- Oil in coolant or coolant in oil
- Rough running and misfires
How to Fix
Replace both head gaskets with the updated multi-layer steel (MLS) design. Have both cylinder heads pressure-tested and skimmed for flatness. Replace the head bolts (they are torque-to-yield and cannot be reused). Also replace the thermostat and water pump while the engine is apart. Consider installing an aluminum radiator to prevent future overheating.

Frequently asked questions
What does P0302 mean on a Land Rover?
P0302 stands for "Cylinder 2 Misfire Detected." This code means the engine computer has detected a misfire specifically in cylinder 2, meaning that cylinder isn't completing combustion properly on some firing events. The computer watches tiny variations in crankshaft speed to spot when a cylinder fails to fire, and a misfire means the air-fuel mixture isn't igniting correctly — usually from a spark, fuel, or compression problem in that cylinder. You may feel a stumble, rough idle, shaking, loss of power, or a flashing check-engine light, and persistent misfires can damage the catalytic converter. Because it names a single cylinder, the fault is often a component serving just cylinder 2, like its coil, plug, or injector. On Land Rover it is documented across 1 model: Freelander.
What are the most common causes of P0302?
The most common causes of P0302 are: Worn or fouled spark plug (cylinder 2), Failed ignition coil or coil-on-plug (cylinder 2), Clogged or faulty fuel injector (cylinder 2), Vacuum or intake air leak affecting that cylinder, Low compression (worn rings, burnt/bent valve, head gasket), Damaged spark plug wire or boot (if equipped), Carbon-tracked or cracked coil/plug causing spark loss, Faulty PCM/ECM driver (rare). The specific cause varies by vehicle.
How much does it cost to fix P0302 on a Land Rover?
Published repair estimates on Land Rover range from $1,500 to $3,500 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.
