I don't know Mark Carter and have never met him, but since joining on here a couple of years back I have come to realize that he is what most of us would accept as a specialist, an expert on diesel systems.

A Bosch instructor, if I am not mistaken and answers posts in a way he would in a course environment I would think.

The printed word is not as personal as the spoken word and sometimes can be misinterpreted in a way that was not intended. This should be kept in mind when, either reading or writing a post.

The old saying goes "it's not what you say, but how you say it" and I sincerely hope nobody see's this as having a go at anyone.
