Manual said I need to do servicing once in every two years or 20k miles...I have started driving as Private Hire and already reached to 10k+..last full servicing was done 3months ago..so shall I consider doing service again or I can wait until 20k..someone advise me please. Thank you.

If your car is on variable servicing it's once every 18k or 2 years, but will tell you in the infotainment under "service" exactly when due. If it's on fixed it's every 10k or a year.

 

Makes sense to go longer with the mileage you do.
