Obviously too late to help the original enquirer in March , but someone else may appreciate it, I do Nullarbor & in WA regularly in Motorhomes etc & I have been using Paul from Van Master Repairs in Malaga just off the freeway since 2009 he originally was Mobile in a Sprinter Van in early days but nowadays great workshop & he has Mercedes Fiat Renault VW in there always , his knowledge on them would be hard to beat
