I work for Toyota and the injection flush is really not needed on a 10k... It's just fuel and cleaning additives that's hooked up to the fuel line off the top of the fuel filter and run the car until the can is empty... We charge something like $90 per service... It's not Toyota that sells it, it's another company that has reps at dealers that ring all the customers and bull**** to the customers that "Your service advisor has requested that you have the flush done" and stuff like that... There is no need to get it on a service at all... When the car has a lot more kms on the clock, and you can feel that the injectors are clogged, then try a flush... If they are still clogged, then take them out and get them professionally cleaned in an injector cleaning machine... And back to the topic, the only parts needed for a 10,000km service on a Rolla is an oil filter and the sump plug washer...
