About MyT1N

This site started because of one specific 2006 Sprinter T1N — a high-mileage diesel van I named Pat. Every time Pat hit a new problem, the answer existed somewhere — on Sprinter-Source, in a workshop manual, in a Florida Van Man video — but finding it meant skimming twenty-year-old forum threads, comparing conflicting advice, and trying to reconcile it with what the manual actually said.

So I built the tool I wished existed: a chat that pulls from the entire body of T1N material at once, asks the kind of follow-up questions a competent mechanic would ask, and commits to ranked hypotheses with citations back to the source. Every claim links back to the original document or thread it came from — torque specs, fault codes, diagnostic steps — so the answers are checkable, not invented.

The corpus took a while to assemble: every T1N PDF I could find, the full Sprinter-Source archive (paginated, with thread-level tagging), and the two YouTube channels owners actually trust.

Once it worked well for Pat, I kept using it. Then I built a browseable catalog and dedicated issue pages so other T1N owners could explore without having to phrase every question as a chat prompt. The trusted-shops directory is the same instinct — when a job genuinely needs professional hands, point owners at the people the community actually trusts.

It's a deliberately narrow tool. One platform, one community, sources that are real and limited. That constraint is what makes it work.
