The service centre has probably put to much engine oil in. Check on your dipstick with the car on level ground and if near to the top mark or over drain some engine oil out. With the diesel that can collect in the sump this will give a rise that once over a certain level triggers the message. Always check the oil level after a service on the dipstick as the electronic message can take some mileage to give a true reading and clean oil shows it has been changed.
