FAQs 

1. What is the function of the fuel vapor canister vent hose in a BMW?
This hose links the fuel tank to the charcoal (or vapor) canister, allowing fuel vapors to be stored and then routed back into the engine for combustion. It helps maintain correct pressure in your EVAP (evaporative emissions) system.

2. What are the signs that this vent hose may be failing?
Common symptoms include:

• A persistent fuel smell around the vehicle

• A check engine light, especially with EVAP-related fault codes like P0442, P0455, P0456, or P1449

• Difficulty filling the fuel tank (the pump may click off early), due to pressure issues

3. Can a damaged or clogged vent hose affect my car’s performance?
Yes. If this hose leaks or is blocked, it can disrupt the pressure levels in the EVAP system, potentially causing diagnostic trouble codes, and may lead to poor fuel vapour routing.

4. How is a failing vent hose diagnosed?
A common method is a smoke test, where technicians pressurise the EVAP system with smoke to identify leaks in hoses, canisters, or valves.
Additionally, using a scan tool to check for EVAP-system fault codes gives good direction.

5. Will replacing this hose fix a check engine light due to EVAP codes?
If the fault is caused by a leak or damage in the vent hose, then yes — replacing it often clears that type of EVAP error. But if other EVAP components (like the purge valve or the canister itself) are also faulty, further diagnostics may be needed.

6. Is the replacement hose an OEM part?
Yes — part number 16117439919 is the correct specification hose for many BMW models and is designed to match OEM performance and fitment.

7. How do I install this vent hose?
Installation typically involves:

• Locating the fuel vapor hose between the tank and canister

• Removing any clamps or fasteners

• Replacing the old hose with the new one, ensuring secure connections at both ends
  If you’re not confident working with EVAP systems, it’s best to consult a professional mechanic.

8. Can I drive with a damaged vent hose?
It’s not recommended: a leaking or cracked vent hose can let fuel vapour escape, cause EVAP system errors, and potentially impact emissions. Replacing it promptly reduces risk and ensures your evaporative emissions system functions properly.

9. Does this product come with a warranty?
Check with the seller for specific warranty details, but typically, parts like this come with a 12-month or similar manufacturer/retailer warranty.
