[wully]

The obvious thing to check for is there an air leak ?

[MINI William]

I would say an air leak somewhere in the system

It'll be a vacuum leak somewhere but if there isn't any fuel leaking anywhere then I'd say it could perhaps be the non return check valve. Sounds like you may need to find a better garage if they're struggling with problems like this.
