WUQ BM500 Car Electronics Accessory

BMW MINI Diagnostics & Battery Registration Tool

The ANCEL BM500 is an OBD2 scanner built exclusively for BMW, MINI and Rolls-Royce models from 1996 onward. It reads and clears fault codes across all major control modules including engine, ABS, SRS, transmission and SAS systems. The tool also performs battery registration after replacement and resets service items such as oil, EPB, ETC, CBS and PCM adaptations. It suits owners and independent workshops that need dealer-level functions without dealer pricing.

Thermals Noise and Power Draw

The scanner draws its operating power directly from the vehicle OBD2 port so no external supply or internal battery is required. It runs silently with no fan or moving parts and generates negligible heat during normal diagnostic sessions. Typical current draw is low enough that it will not affect vehicle battery voltage while the ignition is on and the engine is off.

Model Coverage and Reset Scope

Supported chassis codes include 1 Series E81 E82, 2 Series F22 F23, 3 Series E90 E93, 4 Series F32 F33, 5 Series E60 E61, 6 Series E65 E66, 7 Series E38 E65 and 8 Series G14 G15. Reset availability varies by specific model and year so not every service function works on every vehicle. Buyers who need coverage for brands outside the BMW group or who require bi-directional control and coding capabilities should look elsewhere.
