Does the ‘640 mod’ work on our cars?

I did it on my RS4 and had it removed for a couple of years. Only put the relay back in when I sold it.

What’s the biggest difference you noticed? Over standard.

I liked the extra weight it gave to the feel of the steering. I do a lot of road trips to the Alps, Wales etc and I felt that the steering was a little too light for my liking.

Give it a go - takes 5 mins and is easily reversible if you don't like it.
