P0441 on BMW: Causes, Symptoms and Fix Cost
Quick Answer
Safe to drive (short-term)
P0441 on a BMW means the engine control unit detected that the evaporative emission system is not purging fuel vapour at the rate it commanded. The ECU opens the purge valve and expects a specific flow of stored vapour from the charcoal canister into the intake. When the measured flow is too high or too low, this code sets. The cause is almost always a purge valve that is stuck or not opening, or a vacuum line that is cracked or disconnected.

The Quick Answer above is the generic definition. What follows is the model-specific detail for the BMW models that log P0441.
BMW 3 Series
2005-2013
On the N52 the tank vent valve (BMW's name for the purge valve) is fitted at the bottom of the intake air manifold, with a plug and hoses attached. Check those hoses and the plug as well as the valve.

What causes P0441 on a BMW?
Beyond the generic causes listed on the main P0441 page, these are the patterns noted for BMW models:
Tank vent (purge) valve not flowing as commanded on the N52
: BMW 3 Series
Loose or cracked hose at the tank vent valve or intake manifold
: BMW 3 Series
How to diagnose P0441 on a BMW with OBD2
- Read the freeze frame data stored with the code. Note the engine load, coolant temperature, and fuel level at the moment P0441 set. This tells you whether the fault appears during a specific purge phase, which narrows down the valve versus a flow restriction
- Inspect the purge vacuum line from the valve to the intake manifold. Look for cracks, a disconnected or split end, or a collapsed section. A disconnected line is one of the most common causes and is quick to spot
- Perform a smoke test on the EVAP system to confirm the hoses and canister are sealed and routed correctly. This rules out a leak or blockage before you condemn the valve
- Command the purge valve open and closed with a bidirectional scan tool and watch the flow. The valve should click and pass vapour when commanded open and seal fully when commanded closed. A valve that does not open, or one that stays partly open, will set P0441
- Inspect the charcoal canister and vent valve. A saturated or restricted canister, or a vent valve that will not let air in during purge, prevents the commanded flow and produces the same code
