P0496 on MINI by model: symptoms, diagnosis and fix
MINI turbo models have documented EVAP purge/vent valve failures that can allow excess fuel vapor into the intake, causing hard starts after refueling, rough idle, and occasional stalling. Owners often report a fuel smell and drivability issues that are worse immediately after filling the tank. This issue is commonly referenced in MINI service literature and owner reports for N18/B48-era vehicles.
Common Symptoms
- Hard start after refueling
- Rough idle or stumbling
- Fuel smell near engine bay
- Occasional stall at idle
- Check Engine Light with EVAP-related codes
How to Fix
Replace the EVAP purge valve (tank vent/purge solenoid as applicable by engine) and inspect EVAP lines for cracks or disconnections. Clear codes and verify proper purge operation with scan-tool activation tests; ensure the fuel cap and filler neck seal correctly.

Frequently asked questions
What does P0496 mean on a MINI?
P0496 stands for "Evaporative Emission System High Purge Flow." P0496 means the evaporative emission (EVAP) system detected high purge flow — fuel vapor is flowing into the engine when it shouldn't, typically because the purge valve is stuck or leaking open. The EVAP system captures fuel vapors in a charcoal canister and meters them into the intake through the purge valve at the correct times; unexpected vapor flow can create a vacuum in the tank and disturb fueling. Symptoms can include rough or stalling idle (especially after refueling), hard starting, or a fuel tank vacuum noise when the cap is removed. On MINI it is documented across 1 model: GP.
What are the most common causes of P0496?
The most common causes of P0496 are: Stuck-open or leaking EVAP purge valve/solenoid, Faulty purge valve electrical control or wiring, Damaged or disconnected purge vacuum hose, Faulty vent valve allowing improper flow, Failed fuel tank pressure sensor, Cracked or pinched EVAP lines, Carbon canister saturation or failure. The specific cause varies by vehicle.
How much does it cost to fix P0496 on a MINI?
Published repair estimates on MINI range from $180 to $650 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.
