Hello, I took over a PHAETON 3.0 diesel year 04/2012 at 26.770 km. At this km stand also a service with LongLife oil was carried out. Today, at km 36642 the message on the display appears that after 5100 km another service is due. Then the service interval would have been only 14.972 km. With the models before – same engineization – was always 30,000 km. Does anyone have an explanation? Thank you and many greetings Wollibär
