2012 Volkswagen Golf Gti 155Kw

VW Golf 2.0 GTI Great little car. Comfortable, Serviced. New WOF, rego Few scuffs as expected for a car of this age. Selling as is! Seems once warm there is an intermitant fault with the gearing, guessing it could be the mechatronic unit. Doesnt do it all the time. Could be an easy fix for somone with the know how.
