Why California customers mail in battery bms repair / reset

California has roughly 31 million registered vehicles, and European luxury (BMW, Mercedes, Audi) make up much of what Los Angeles-area shops and owners mail us. Battery BMS Repair / Reset is a bench job most Los Angeles shops don't keep equipment for, so owners and trade shops across California ship it to a specialist. Cross-country west — about 2-3 days each way.

Is there a battery bms repair / reset shop in Los Angeles I should use instead?

Does California vehicle inspection or emissions testing affect this service?
California requires a biennial Smog Check emissions inspection in most counties through the BAR program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all California and federal requirements.
Do I need proof of ownership for this?
No — a BMS repair isn't security or immobilizer work, so there's no proof-of-ownership gate on this service. The only thing we ask you to do first is verify your exact unit: send a photo of the battery/BMS label and your symptoms so a technician can confirm we cover it and that the fault looks like electronics rather than dead cells before you ship.
How much is it and how does the mail-in work?
It is $250 flat. After a technician confirms we cover your unit from your label photo and symptoms, you ship the battery or BMS module to Auto Module Lab in Arlington, TX. We repair and reset on the bench, test that it charges and communicates, and ship it back with tracking — return speed your choice at checkout (Standard $29.95, UPS 2-Day $54.95, or UPS overnight $94.95).
