My friend sent her 2009 Jazz to USJ1 Honda for a 40000kms service, they told her that at 40000kms, they have to clean the throttle body @ rm288, and they have to clean all the injectors for rm168, although it is not in the service booklet. I have never heard of such a thing from any of the other manufacturers. Is Honda so high tech now that they have to have this done? Anyone in this forum heard of this or had their car done?
