More questions
Do I need to run adaptations after fitting?
Often, yes. Many gearboxes need clutch or shift adaptations after any control unit change. That is normal and is done in the car with a diagnostic tool.
Can you clone a mechatronic unit with oil in it?
Please drain and wipe it and seal it in a plastic bag. We work on the electronics only.
