VIKINGNZ 14 Report post Posted December 10, 2021 (edited) Good Morning All, I bought a F30 BMW320D 2016 the mileage is 59000km. As per the service history everything all consumables has been changed on regular basis. Once already the break liquid has been changed. My question is when do I need to change the cooling liquid, the oil of the gear box, the oil of the differential etc etc. I would appreciate your thoughts and assistance please. Thank you in advance.
