Hi all seem to fix one problem and another comes up like whack a mole on my 4.2!

Any idea what this noise is - no faults sound a bit like a misfire but more of a thud?

Weird I record it on my phone hear it clear as day uploaded to YouTube and I can’t hear the noise! Hopefully you can my YouTube is maxing our playback to 480p you will want it best quality Hs you can to hear Current stable:
