Leon Cupra ST 5F “First oil change… several questions….???

Hello dear FAN – municipality. Use your help or your experience! The following conditions: Leon ST Cupra 5F – first registration 01.04.2015 (day registration/exhibitor) Date of purchase 01.06.2015 2 questions to you: 1. Onboard computer showed me 30 days ago: “Oil change in 30 days”. According to my knowledge first oil change after a year or 20,000 km. My km stand: 4600!!! So: neither the year is full nor the 20,000 km and that at LongLife oil!!! I called the workshop. It was there today. There would be no mistake. Could be because I drive extremely short distance / Cupra mode. Drive the car but normal (first time in). So it would have to be changed oil and filter to get factory warranty. Then asked politely if I would drive to the Nordschleife in the summer, if he would have to change oil every 1000 km!!! That can’t be possible! 8 months and (as of today) 5400 km … and this with Longlife Oil! What can you tell me, or when did the model show you the first oil change/filter? 2. The bill! 58.60 € Wage – 5.7 L LongLife Oil – Filter = 258 € After what I read, 182 € to 210 €. What did you pay for the first oil change with filter? The same or did I end up in a “Hugo Boss” luxury workshop? I would be very pleased about your answers or experiences!!! Greeting Guido
