Interesting, several people report good results from fitting one to a DSG car - page 2 of this threadhttp://www.golfgtiforum.co.uk/index.php?topic=276185.msg2524427#new
Yes, with some more digging there are reports of people with DSG Rs fitting them and then removing them after having sensitivity issues.This is a shame as I hate the initial dead feel of the Rs throttle and am seeking a solution.
I'm sure if it doesn't work DTUK will take it back.They have a good customer service.
But several people are using it with DSG so its not as if you re throwing your money out the window. If it doesn't work there is nothing lost but time.
