Intermitttent car horn

[TOM.C]

Hi guys, currently I am facing a problem of my F30 intermittent car horn issue. Previously when its still under warranty, I bought it down to PML for rectification & was told that it was some contact issue, problem do went off for a short while & came back just after my warranty ended.. Headache.... Guys any good & reasonable price workshop & mechanic to recommend.. Thanks..
