Sorry for the late reply, I haven't logged into this forum in a while. Most techs won't make a big deal out of it. But if its something you can do relatively easy I would do it. If you do happen to get that 1 ******* technician who makes a deal out of it, they can possibly note it in the infiniti database and you may have a hard time trying to squeeze things under warranty. Its a small chance, but why risk it if the task is simple for youMay I ask ' Do you think I should take my OCC out ? It was just in for the 30k service and they didn't say anything about it .
