BimmerLight Pro

Your check-engine light just came on — now what? BimmerLight Pro turns your phone and a cheap ELM327 Bluetooth adapter into a BMW diagnostic tool that actually tells you what's wrong, in plain English.

Plug an OBD-II adapter into your car, pair it once, and read the same fault codes a shop charges you to see — then clear them and reset the light yourself.

WHAT YOU CAN DO

• Read fault codes — stored and pending trouble codes, pulled straight from the ECU

• Understand them — each code comes with a plain-English meaning and the most likely causes

• See freeze-frame data — the RPM, load, coolant temp and speed captured when the fault stored

• Clear codes & reset the light — with an honest heads-up about what that does

• Watch live data — real-time gauges for RPM, speed, coolant, intake air, load, throttle and voltage

• Check your vehicle — decoded VIN, protocol and adapter info at a glance
