I have raised the issue with the other moderators/admins of X5world.
My personal opinion is that we would then have to consider addressing each engine specifically, not just the diesel. While I sympathize with your situation I think that diligent use of the search function and original posts with clear post titles effectively provide those with 3.0d issues access to previous posts. I have been seeing more old posts being resurrected lately which tells me that the search function is working to help find previous posts on same topics.
Perhaps a compiled list of known or common 3.0d engine issues and solutions could be created and posted on the X5world homepage as an article for permanent reference. Hint, hint.
