Need some help I've got a 2013 vw golf 1.4tsi with and auto dsg gearbox recently been giving me gearbox warning error. Have scanned car with vcds and it shows transmission in limp mode, gear 1 not selectable, clutch 1 tolerance limit reached, and clutch 1 clearance too small. Also been told the gearbox is nok serviceable as it is a lifetime gearbox. Any idea what could be the problem also when gearbox warning comes up car skips 1st 3rd 5th gear while driving.
