FAULT · ANALYSIS · TRUST
Know what's wrong with your BMW before you pay a mechanic.
Plug in a cheap Bluetooth dongle or just describe the symptom. Get a ranked diagnosis, the parts you actually need, real cost estimates, and trusted local sellers and fitters — so the "German cars are expensive" markup stops at the door.
Read the fault
Dongle codes or plain-language symptoms — the engine handles both, even faults a dongle can't reach.
Get the part number
Each likely cause maps to the exact part, so you never buy the wrong one.
Find local supply
Jump straight to verified sellers who stock it and fitters with transparent quotes.
Built for the BMW fleet
Starting deep on the E46 — the chassis with the largest local parc and the richest fault history — then widening across the E90, E60, F30 and X-series as the knowledge base grows from real outcomes owners report back, market by market.
