[Matthew mk2 TT]

Morning guys and girls hope your well. New to the page and was wondering if you can help me. My TT mk2 has intermittent Quattro issues what can this be ? I've heard normally it's the controller? Is the blue upgraded one the one to go for and where and how much can I get it for ? Thanks in advance!!!!
