knocking noise when pulling away !!fixed!!

Over the last six weeks I noticed a knocking noise when pulling away and heavy braking, I done the usual checks, suspension, drive train shockers, loose panels/wheel arches and started scratching my head so I found a quiet car park and opened the door and stuck my head outside to get a clearer indication of where the noise is coming from so I pulled away and no noise, on closer inspection I noticed the the door was proud of about 2mm, I adjusted the door receiver and hey presto the noise has gone,

now the tratter boys would not like that as they believe they fall off.
