Fehlercodes
Um Fehler aus dem Dachsteuergerät auslesen zu können wird eine Diagnose-Hardware benötigt die Fehler über ein CAN Protokoll auslesen kann.
TECH2
Das TECH2 steht oft nur Werkstätten zur verfügung und ist auch sehr teuer in der Anschaffung.
OP-Com
Die OP-Com Diagnosegeräte gibt es oft auch als Clone und eignen sich hervorragend zum Fehler auslesen
oder sogar programmieren. Empfohlen wird der "Bulgaren Clone" da dieser stabil läuft und eine deutsche Software hat. Kostenpunkt ca 90€. Wer nur Fehler auslesen will wird aber auch mit dem "China Clone" für 20€ glücklich.
Happy Blue Delta Modul
Das HBD Modul verfügt über eine Bluetooth Schnittstelle wodurch Fehler sehr bequem über eine Smartphone-App ausgelesen werden kann. Natürlich ist das noch nicht Alles. Man kann Live-Daten vom Motor anzeigen und gewisse Komfort Funktionen freischalten. Kostenpunkt gebraucht ca 60€
