Volkswagen engine ECU cloneOn-car software step — remote ODIS, $250
Some cars still want an on-car step after a module swap: a software version management (SVM) update, coding, or a basic-settings adaptation. Plug a J2534 pass-thru interface into the car and we run the factory ODIS software on it from our bench — no dealer visit. The same session covers coding after any other VW or Audi module replacement.
