r53obd

r53obd is a diagnostics, logging, and coding app built specifically for the first-generation MINI Cooper — the R50 hatch, R52 convertible, and R53 Cooper S. 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.
