H.A.H.N.S

Hardware, Advisories, Highlights, & Navigation Specialist (mascot: "Hahns")

A no-install browser helper for VW technicians. It reads the repair procedure you already have open in ELSA2GO and lists the things you need for the job — torque specs, one-time-use parts, fluids & capacities, special tools, and critical warnings.

It ships as a bookmarklet (just a bookmark) so there's nothing to install.

Get it / share it

Live setup page: https://flatratelabs.github.io/hahns/

Send techs that link. They open it, drag the H.A.H.N.S button to their bookmarks bar, and they're done — nothing installs.

Shipping an update

After initial install, Hahns will check automatically for an update once a day. Go to settings(gear icon) to manually check for updates

Changelog

What changed in each version, newest first: CHANGELOG.md.

It's also shown on the setup page (under "Current version") and pops up once in the panel after a tech updates to a new version.

Privacy by design

• Runs entirely in your browser. No server, no network calls(except once daily update check), no analytics.
• Only reads text ELSA has already displayed to you.
• Saves no files.

Using it

1. Open https://flatratelabs.github.io/hahns in Chrome, Edge, or Safari.
2. Drag the H.A.H.N.S wrench button onto your bookmarks bar.
3. On any ELSA2GO procedure page, click the bookmark — the HAHNS panel appears.

5. Navigate to the Overview for Rear brakes and select the correct overview for your vehicle
6. Click Scan Page

9. You can manually edit each component populated by Hahns to any name you wish

11. If Hahns has added something you do not wish to have or do not need, simply click the trash can to right of the component to delete it
12. Navigate to any other pages you may need. I suggest going to the removal page for the job you are doing. Example Remove Rear Brake Pads
