Motorcycle VIN decoding: entering a bike VIN (full 17 characters or the last 7) now finds the bike — the ranges were in the data all along but a build bug made them unreachable. The same fix gives motorcycles production dates: build-date filtering works on bike diagrams, and bikes show real year ranges in Compatible vehicles on part pages.
Diagrams inside Compatible vehicles: on part pages, each model under a compatible chassis expands to the diagrams that show the part for that model, linking straight to them. Clicking a chassis now opens its model list in place instead of jumping to a chassis page.

Diagram breadcrumbs name the group and diagram — "11 Engine › 11_1478 Waterpump - Thermostat" instead of bare numbers.

Diagrams for your vehicle on part pages: with a vehicle selected, a part page now lists the diagrams where that part appears on your vehicle (respecting its build date), each linking straight to the diagram. Part links across the site keep your vehicle selection as you browse.

List prices: parts now show a list price in US dollars, converted from BMW's August 2019 German (EUR) price list — the last column of diagram tables and search results, and on part pages, where exchange parts also show their core charge. Period prices matching the dataset's era; current prices differ.

The vehicle picker pre-selects the USA market as soon as you choose a chassis, so the model list appears right away. Pick a different market from the dropdown to change it.
The transmission dropdown in the vehicle picker greys out when the vehicle offers no choice (automatic only, or the catalog doesn't distinguish), instead of looking like a broken control.

Compatible vehicles on part pages: every chassis a part fits, labeled with the part's own usage years rather than the chassis build range, each row expanding to its models with per-model year windows. (Replaces the "Used in diagrams" list.)
Phone header fixed: no more sideways scroll — compact square logo on small screens, and pages with a vehicle chip get a two-row header with a full-width search.
Vehicle picker survives back/forward: when the browser restores your previous selections, the dependent dropdowns now reload instead of leaving the form stuck.
Clearer chassis picker: facelift catalogs read "E60 LCI (2005-2010)" instead of "E60N", every entry shows production years, and the body style appears when the chassis has just one ("E90 … — Sedan").
Copy buttons next to every part number on part and diagram pages.
Diagram tables show a dim "Not applicable" row for callouts drawn on the image that don't apply to the selected vehicle, instead of skipping them silently.

Conjunction wire: parts usable "only in conjunction with" each other are bracketed by an amber wire with arrows on the diagram table; hovering any row highlights the whole group.
