i would have thought if the box was out it would be no problem did he need vag.com for that job? as id think if you need it to change the oil
you would need it to have the box out
To change the oil,you need oil and the sockets to open the drain and filler bungs , oh and some oil. Thats about it, i would be worried about a garage that gave you such an excuse tbh....GULP!
