P0496 on MINI
Evaporative Emission System High Purge Flow
P0496 on MINI vehicles indicates evaporative emission system high purge flow. Au7o has documented this code across 1 MINI model — most commonly on GP. 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. Typical repair costs on MINI range from $180 to $650, depending on the specific model and root cause.
Common Causes of P0496
- •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
P0496 on MINI by Model
MINI GP(1 issue)
- EVAP Purge Valve (Tank Vent Valve) Stuck Open Causing Rough Start and Fuel Smell2013-2021
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.
