Diagnostics are free for everyone, on every control unit, high-voltage battery included. Unlock your own cars for good with a car licence, cover every car that comes through the door with the workshop plan, and program any car with a programming pass.
See everything that is wrong with the car, on every supported Porsche.
Every diagnostic and coding function on your own cars, for as long as you own them.
Programming needs a programming pass (€49 per car, 7 days). Each car is assigned from the app when it is connected, within a year of purchase. A licence never transfers if you sell the car.
Get STEUER14Every car that comes through the door.
Software updates on one car: every control unit, every container and every retry for 7 days. Buy it in the app with the car connected, before programming starts. Included in the workshop plan. A dealer charges €200–400 for one software update.
You pay for the car, never for single control units. Diagnosis is free on every unit; everything that changes the car comes with a car licence or the workshop plan.
