    VCDS 18.9 Engine Adaptations

    Thanks. It should be a drop down option in adaption channels in engine control module 01. For some reason there is only a few options when I select the channel drop down list. Have tried putting in the security code to access adaptations but it doesn’t work. It has me puzzled..any ideas??

    Anyone advise on how to access full Adaptations list in engine controller on vcds 18.9? Only a few options available even after putting in access code in security. Specifically looking to adjust idle RPM. Thanks
