Certain components on your Porsche require coding when they are replaced and PIWIS is needed for this. Examples are engine control modules, headlight control modules, spoiler control modules and so on. To make matters worse, some of these are linked to the car’s immobiliser. For security reasons there is an extra layer of coding and, to code these, Porsche require sight of the log book and a letter from the owner allowing them to release codes to us. The Porsche PIWIS tester enables us to do this coding without you having to take your car to Porsche.
