Hello,

Usually the MDS kit will come with instructions. Here is a link so you can go over the job step by step.

You will need to remove the cylinder heads just to let you know. Disconnect the battery and drain the coolant.

Also, you must disable MDS in the tune (otherwise it will try to command MDS and you’ll have problems). Change the oil and filter once the repairs are competed. If you have any issue just upload an image or short video so I can help walk you through the job. Ken
