What's new
This site ships fast — sometimes an integrator asks for a feature on a Thursday and it exists by Saturday. Here's what's landed recently, and below that, everything OLP does in one list.
The codes cheap scanners spit out that generic sites can't translate — BMW internal hex faults (2A87, 29E0…) and the full CC-ID dashboard message library — now resolve right here, each with its OBD equivalent, symptoms, causes, and what to check first. VAG 5-digit codes too.
Look up a code →Every generic OBD-II range is now complete, plus deep manufacturer-specific fills (P1, body, chassis, network) for 15 brand families. Every code carries symptoms, ranked causes, and ordered diagnostic steps — not just a name.
Browse DTC codes →Fuel, ignition, charging, starting, cooling, transmission, body electrical and more — each with a symptom table, the diagnostic order that prevents parts-cannon spending, the classic mistakes, and that system's codes. Written for techs and serious DIYers.
Pick a system →Every manifold gauge scenario as a visual chart — both low, both high, needles converging, low side in vacuum, rapid cycling — with causes ranked and next checks. Tap any scenario to enlarge it right at the workbench.
Read the gauges →One factory engine code (CJXA, CCTA…) returns labor data for every vehicle sharing that engine across VW, Audi, SEAT and Škoda — because they're the same machines wearing different badges. API: labor-times?engine_code=CCTA.
API docs →SEAT Leon, Alhambra and Toledo, VW Polo, T-Roc, Touran, Sharan and ID.3, Škoda Yeti, Rapid and Enyaq, and more — built from their platform twins with diesel variants included and fuel-aware data (no spark plugs on a TDI).
Find your car →Send a VIN and a plain-text job ("brake pads") and skip slug lookups entirely. Trim-suffixed models auto-correct, near-miss engine slugs resolve, non-US regions fall back to US data, and every 404 tells you what IS available. Every assist is reported in the response.
See what changed →The complete Lamborghini, Ferrari, McLaren, Aston, Bentley, Rolls-Royce, Maserati and Lotus catalogs went through a full precision audit calibrated against real exotic-shop invoices — over 60,000 times corrected, and 38 special-series submodels added (Huracán STO, 488 Pista, F12tdf, the Black Badge family…).
Browse the exotics →Roughly 1.5 million entries for parts vehicles never had — leaf springs on unibody sedans, kickdown cables on modern automatics, VVT on carbureted classics — removed catalog-wide. If a job is listed on your car now, your car actually has that part.
How our data works →Dealer techs told us the same thing: pulling a book time on their phone beats the walk to the OEM terminal. The honest arithmetic, what fits (and what doesn't), and three rollout paths — starting with "it's free, bookmark it."
The dealer page →Every time now wears its confidence: Verified, Calibrated, or Book-style estimate — with a one-tap way to flag anything that looks off. Corrections get reviewed by a human and propagate to sibling vehicles.
See it on any labor page →Which windshield, bumper or mirror jobs on 2016+ vehicles require ADAS calibration — every entry individually verified before it shows. Rolling out across 838 models and counting.
On the labor pages →Everything OLP does
The full toolbox — every one free unless marked.
