These cars are too old for most modern diagnostic and coding apps, which start at the newer CAN-bus models. r53obd speaks their language. CHOOSE YOUR ADAPTER • OBDLink MX+ (Bluetooth) or OBDLink CX (Bluetooth LE) — the full experience: diagnostics, active tests, and module coding. • Any generic Bluetooth LE adapter (Veepeak and similar) — perfect for the free diagnostics tier: live data, fault codes, and VIN. Module coding and active tests need a coding-capable adapter (MX+ or CX). FREE • Live engine data — RPM, boost/MAP, coolant & intake temps, throttle, fuel trims, lambda, timing, knock, wheel speeds, and more • Read & clear fault codes — in plain English, with MINI-specific detail generic scanners miss • Emissions readiness monitors and VIN • CSV data logging — capture a drive or a full-throttle pull and export it • Guided cooling-fan test — pinpoint the classic first-gen fan/relay failure • Read a module's coding — see exactly how your car is configured before you change anything • Demo mode — explore the whole app with sample data, no adapter required PRO (one-time unlock — no subscriptions, no per-car fees) • Module coding — enable and adjust body and comfort features the factory left off, each change backed up first and read back to verify it took (roll back anytime from Coding backups) • Active tests / actuator controls — relays, fuel pump, A/C clutch, cooling fan, injectors, and more, with safety gating and confirmations • Adaptation resets — clear learned fuel, idle, and knock adaptations after service or parts changes • Service routines — an ABS/DSC brake-bleed cycle, a service-interval (SIA) reset, and instrument-cluster self-tests (needle sweep and warning-lamp check) Built for the enthusiasts and DIYers who want real numbers from the supercharged Cooper S and honest diagnostics across the whole first-gen range. Designed for iPhone and iPad. REQUIRES a compatible adapter (sold separately). A generic Bluetooth LE adapter covers the free diagnostics tier; module coding and active tests need an OBDLink MX+ or CX. For lawful diagnostics and maintenance on a vehicle you own. Airbag/restraint coding is never touched. r53obd is a product of RABRH LLC.

Diagnostics • Improved fault detection across multiple modules for more complete and accurate results. • Enhanced fault clearing with better confirmation when a module accepts or refuses a clear request. • Improved scan reliability to reduce incomplete diagnostic results. • We recommend performing a fresh fault scan after updating to benefit from the latest diagnostics improvements. Coding • Improved Park Distance Control (PDC) coding support. If you created a PDC backup before updating, we recommend saving a new one. (primarily r52 convertible) • Coding option names are now consistently shown in English. • Restore points are now clearly identified before coding changes. Also new • Log filenames are now consistent across all your devices. ### 1.1 — 2026-07-18 • More ways to connect.
