About
560 SL Workshop
A focused troubleshooting tool for the 1987 Mercedes-Benz 560 SL — chassis R107, engine M117.967. Built for owners, weekend mechanics, and indie shop techs who want a fast way to walk a symptom down to a likely cause without trawling four forums and a dusty CD of WIS at the same time.
How the references work
The app indexes the structure of four community sources into its own database: the URLs, page titles, group/section codes, and a short snippet of body text — nothing more. When a leaf in a decision tree cites tonk.ca, mercedessource.com, peachparts.com, or the MBCA Star magazine archive, the link opens that source directly in a new tab. We do not mirror, rehost, or proxy any article content.
Search runs against those titles and snippets, not against full-text scrapes. If the source goes offline, the link goes with it.
How the diagnostics were written
Every decision tree is hand-authored from platform knowledge of the M117.967, R107 chassis, KE-Jetronic (CIS-E) fuel injection, the 722.3 four-speed automatic, the Bosch 2U ABS unit, and the pushbutton ACC climate control. Where a step has a published reference — torque value, voltage spec, vacuum reading — the leaf cites it.
These trees are a diagnostic aid. They are not a manual replacement, and they do not cover every failure mode of a 38-year-old car. When in doubt, defer to the factory service manual.
Parts links
Supplier pills (FCP Euro, AutohausAZ, RockAuto, Pelican Parts) point at pre-filled search URLs on each vendor's site. Clicks route through an internal /api/go redirect so we can log which references actually get used and prune dead links.
Affiliate disclosure
No affiliate programs are active right now. Supplier pills route through /api/go for click logging only — no referral or tracking parameters are appended to the destination URLs, and 560 SL Workshop earns no commission.
