Pump like noise

[mark9208]

Hi forumers,
My c207 developed a “buda buda buda buda” or pumping like noise when on idle after driving. This noise is aggravated when the car is reversing even on a slightly steep slope. Dealership have even changed the fuel pump and charcoal canister but it was no use. I am attaching a video for you to hear and give me any ideas as to what to look for.

Sounds like the clip that holds the parking brake cable away from the propshaft has broken and its rubbing on it.

Thanks for the reply and had that checked but it was all tight. Just want to update my problem in case any other owners are face the same issue; the tech released the gas cap and the noise stopped completely. He said it was due to pressure build up but is unsure how to solve the issue. The cap was changed a year ago. Any ideas?
