Hello, I’m new here and with the help of your search already found out that my Omega has a problem with the throttle valve (error code P 1555 Text: throttle valve setting motor is / should position is not consistent or similar)) and that probably should help a cleaning. Now I have not had much experience with the self-balancing on the car besides braking and changing wheels 😛 (am still quite young and apparently I learned the wrong handwork 😉 ) therefore I am now looking for a detailed and serious guide on how to extend and clean the whole and if something special is to be taken into consideration also reinstalled. Thank you for your help. lg
