Didn't see it for myself but told following 1000 mile service that there was debris on the BB's magnetic drain plug. Not unusual apparently and was told my box is a relatively quiet one, so not too worried. Dealer was happy to re-fill box with the Redline Shockproof heavy I supplied.
Must admit that a 140 mile drive yesterday whilst wearing crash helmet, earplugs and further helped with some sound proofing I fitted, was an absolute pleasure.
Problem is the quieter one noise becomes, the better you hear others - sometimes you just can't win
