What miles has it done, & what was FULLY Serviced, was the Pollen Filter changed, was the brake fluid changed according to the Skoda Schedule now, @ 2 years? VW / Skoda converted km to miles and got 15,000 km to 9,300 with VW,s and for Skoda's 9,400 miles. Then a year and a week from a PDI, allowing for holidays maybe 372 days not 12 months. Variable 24 months / 18,000-20,000. Major / Minor was a decade back, then Interim / Major. Now Oil & Inspection Service and that with Extended Scope each 3 years. The Garage will know what the car needs and when for your usage surely. If you want it,s oil and filter changed at 12,000 miles, or 15,000 then have that done. It could have been left on Variable servicing and not reset to Fixed, 9,400 miles / 1 year (1 year and a week.) PS, Spark Plugs changed 4 years / 40,000 miles or sooner. Air filter checked each service, not as per Skoda / VW, 60,000 miles / 6 years.
