Electrical & Diagnostics
Service & Repair.
Factory-level diagnostic tools — BMW ISTA, Audi ODIS, Porsche PIWIS, Mercedes XENTRY — for fast, accurate, root-cause fixes.
European Auto Electrical & Diagnostic Services
Modern European cars have 60+ electronic control units. A check-engine light on a BMW could be a vacuum leak — or a coded fault in the DME that needs adaptation reset. Cheap code readers can't see half of it. We run the same factory-level software as the dealership and pair it with a decade-plus of European-specific experience.

Electrical & Diagnostics questions, answered.
My check engine light is on — can you diagnose it?
Yes. We run a full factory-level scan (not a generic OBD-II reader) and check across every module for the real cause. Most shops charge for parts that don't fix the problem. We diagnose first.
Why do batteries need "coding" on European cars?
BMW/Audi/Mercedes use Intelligent Battery Sensors that track the battery's age and state-of-health. After replacement, the car needs to register the new battery so the charging system and start-stop system work correctly.
Can you add features my car came without?
Many yes — Apple CarPlay, Euro menus, Euro tail lights, cornering lights, video in motion, coding tweaks. Ask us what's possible for your specific VIN.
