Trouble soon after filling up...

[adm333]

I have recently had several occurrences where soon after filling up, the "restricted performance" warning comes on with varying degrees of actual restricted performance.

in my other car, I had similar issues when a fuel tank breather valve was playing up. All problems went away after replacing it.

so my question: does the SDV6 have any kind of fuel tank pressure release valve or similar breather valve that is prone to failure ?

any insights appreciated

Thanks

Bumping this thread.

When I open the fuel cap on my L320 I notice the sound of air sucking into fill pipe. This tells me the fuel tank breather isn't functioning correctly.

Has anyone experienced the same and come up with a fix?
