Hello guys, I have been the owner of a new C1 for a good month Now my question to you: From which KM stand should I make the first oil change? I have such a number of 2500 km in mind, but don’t know if this is true. and my 2nd request – where can I have the oil change made? Do I have to go to the contract workshop because of warranty ect. or does it work at ATU – the currently oil change offer for 1 € + oil costs? Thank you for your help and reviews! M atthias
