Porsche Regeneration Valve from Throttle Body for Fuel Vapor System - 99611012906 - Genuine Porsche

Will not start after refuelling.

Fixed the no start after refueling problemWas able to snake it in with out removing the manifold. have to connect under the car near left rear wheel.Cut old pipe by manifold then easy to remove vacuum hose clamp.

Good part, overpriced

This part solves a common problem with Boxters having hard starting after refueling and showing fault code P0446. It's a little bit of a challenge replacing due to its location under the intake manifold and the long pipe that has to be threaded down through the pipes and engine accessories to properly attach, but it's doable. Overall, pleased with the part except it's about 50% overpriced.

If you cannot start car after fueling

If you can't restart after fueling this is the part you need to replace, It controls fuel vapor during refueling.
