The following paragraph is from the Office of Fair Trading
Maintenance schedule, Vehicles under warranty Whether new or second-hand, your car or motor cycle should have come with a logbook or owners handbook that sets out when the vehicle should be serviced and what maintenance needs to be done. To keep your motor vehicle in top condition and to avoid the possibility of breakdown or expensive repairs in the future, you should follow the maintenance schedule. If the vehicle is still under warranty and you dont have it serviced to the manufacturers maintenance schedule, you may void your warranty. As long as the service is carried out in accordance with the manufacturers specifications, any licensed repairer can do it, not just the dealer from whom you purchased the vehicle.
