Since this is after the transmission,

Any change in differential ratio will set a gear ratio error code, placing the transmission in limp mode. The only way to correct, coding TCM and ECM with the new ratio.
Hey Steve i'm edging closer to the quaife.

BTW guys the mkd diff is like 4900 euros! wow i didn't remember it being this much.

You need to jump at least 0.50 of a gear ratio to notice a real world change. That being said, you really CAN'T do it with a simple tire change. You will need to drop the overall diameter more than 2" do accomplish this. At that point the car would be dragging on the ground, okay, almost dragging.

See yeah
You're spot on my friend.

I had a Kleeman dealer install my quaife and the never mentioned needing any ECU changes. I haven't had any issues.
