Hi all

Dropped my car off yesterday to get detailed. I get it back and have a mystery knock from somewhere front left it sounds like. Somewhere under dash/pedals or the engine bay.

It doesn’t seem to be consistent (doesn’t start till car starts moving but doesn’t get louder or quieter depending on speed/acceleration). It also doesn’t consistently happen with accel, it doesn’t seem to have a rhythm to it.

It doesn’t sound like it’s serious or an “oh crap” noise but definitely annoying. I’ve taken a look but hard to locate as it only does this when car is moving. Link to YouTube of the noise.

I can post another video if needed. Any ideas?
