I’m in process of swapping a 02q into my alh mk4. So similar but different.
I got the speedo working by representing the cluster to use abs instead of vss. Got the cruise control working by reprogramming the ecu to pull vehicle speed from the abs instead of vss sensor.
I never did get any dtc though so that’s different. Can you delete (hard remove) those dtcs from your ecu bin?
Yeah you can remove dtcs from ecu or tcu
