2011 M56x Throttle Body issue

[magnusbeck]

Has anyone come across a problem with the electronics in the throttle bodies? My dealer is telling me one of mine has gone bad and they want to replace both throttle bodies since the electronics are inherent to the part. They're telling me infinti is "willing to help out" by paying for the parts, which over $2k, but that leaves me paying for the labor.

Have them buy the parts and take them home to swap them yourself. Not hard with a ratchet and a screw driver. Should take a lay man about an hour and a half.

Replace your PCV valves at the same time.

I second ArmedAviator's comment, procedure is not hard at all (including the PCV valves), just take your time.
Look at the FSM (in Ilya's signature line)
You're probably gonna need to do the following after changing your throttle bodies:
ECU accelerator pedal relearning, throttle valve position learning, and throttle position learning procedure (eg. the dance steps) see: reset-ecu-accelerator-throttle-idle-t595740.html

If you don't, you may notice your idle RPMs are too high (supposed to be +/- 650)

Only posting so you can see my signature line, per Doc's post lol.

Do one at a time, it's more often than not the drivers side throttle body. What's it doing? Starting and dying?
