Indicator relay weirdness

On the Audi .
All bulbs working and OK ,all work when on hazard .The relay was buzzing and no lights when indicating left but ok when indicating right .
Have put a new relay in and it's still the same
Where's a Mechanically Trained person when you need one

mechanically or electrically trained?

A relay is both isn't it It's fixed itself now anyway

Your right, a relay is both, and can be fixed in both respects..

You can either fix it mechanically (by wacking it) or electrically (by stabbing an electrical screwdriver in the side and waggling it around a bit)
