Driving at 30mph recently and just started to accelerate, heard what sounded like 'running over a cattle grid' sound together with a puff of white smoke from exhaust. No "fault" signals on dash and continued to drive slowly for another half mile. AA mechanic suspected 'timing chain' or 'diesel injectors', but both checked by my regular garage and no evidence of failure found. Left with 'scratching head'! Any advice welcomed. Thanks.
