Platform 1974 – 1993

240

Rear-wheel drive, overbuilt, and gloriously analogue. There is no data bus to decode because there is no data bus — every reading is a voltage, a resistance or a switch. Which makes it the honest way to learn a car.

Project Gothenburg.

A modern Volvo-style digital driver display for a 1987 244 DL — a Raspberry Pi 5 driving a 12.3″ 1920×720 panel inside a 3D-printed cluster shell. The 240 has no factory CAN bus, so every reading is earned: each gauge is wired from a real sensor rather than decoded off a bus.

The CarPlay-style app hub — Claude, browser, media, all on the 12.3″ panel

240 Spoiler.

A proper rear spoiler for the 240 — adapting the classic 850R wing to the 240's boot with a 3D-printed adapter bracket, plus a printed bumper cooling insert to finish the look. Designed to be sold: this is the first Volvo World part heading for a storefront at 240spoiler.com.

  • 850R-to-240 spoiler adapter bracket, modelled parametrically and printed
  • Matching 240 bumper cooling insert to complete the front-to-back look
  • Being productised for sale — 240spoiler.com is ours and waiting
  • Next step: a large filament batch (Alibaba) so we can print to sell
Status

The design is done and printing. The storefront domain — 240spoiler.com — is ours and waiting. The one thing between here and selling units is a big batch of filament (sourcing from Alibaba); that’s a job for another day.

Factory data, queryable

VIDA, Unlocked

Volvo's dealer workshop system stores its entire service library in a SQL database. Reading it directly instead of clicking through the application turned a three-and-a-half-minute lookup into a sub-second query — and made the whole library searchable at once.

A format nobody could open

Exploded-Plate Decoder

The parts catalogue's exploded diagrams are stored in a binary vector format that no standard tool would open — and the reason why turned out to be a trap: the files claim to be vector graphics, but the actual picture is a single bitonal raster tile hidden inside. Decoding the grid as one continuous strip produces convincing noise; finding the tile boundary produces a perfect diagram.

The junkyard advantage

YardBrain

A private junkyard cross-referencing engine. Point it at a part and it works out every other vehicle that part was fitted to — so a trip to the yard stops being a guessing game. It reads the interchange data the pros use, flags cars that were filed under the wrong VIN, and scores which donor is worth the walk.
