Hello everyone new here and hope someone can help . On way to work friday morning in is 250 . Put foot down to overtake tractor and at about 6000 rpm there was a horrible grinding sound , dashboard lights came on and engine cut out . Wouldn't restart so rang greenflag . Put on diagnostic and read no faults . Took to garage and they got engine to restart but at 2500 rpm engine is making a horrible tapping and clanking sound and cuts out . Been to 2 garages now and both cant diagnose the problem ?? Has anyone any inkling of what this could be or have had the same problem? Thanks in advance.
