A bit of oil consumption that early in the cars life isn't that strange by any stretch, everything in the engine is still trying to settle and work itself in. Also need to always remember more often than not your talking to service advisorsso now after reading everything, Sorry for your troubles, when breaking in the engine, I noticed it used more than normal oil and brought it to the dealer - they immediately told me that it COULD be the turbos leaking and they've already done a few turbos. (what?)
Anyways so if you get new turbos, would you have to re-do the entire break in process again? I'm at 900 miles now and this blows that I can't punch it until 1,200 miles. But, i'm following orders.
most of the time not the mechanics. SA's working knowledge and understand are not what I'd call the most reliable source of information.
Get an oil change done at 1K miles (really good to do during break in period), keep an eye on things for the next 3-5K miles. If you still seeing a similar amount of oil consumption then I'd be concerned.
It's probably an Eddy current sensor they are a very dependable way to provide accurate measurements in nasty conditions, a lot of the publications I've seen call it a "Optical Sensor" which when discussing how sensors operate would be incorrect.LOL! There's a turbocharger speed sensor installed on the compressor side of each turbocharger. That's the only cable coming off the turbochargers that I'm aware of.
I'm a little confused as to the term "optical speed sensor" though. The FSM describes the turbocharger speed sensor as being an eddy current sensor, not optical.
But if you were to describe it based on functionality then it somewhat work as a loose description.
"The <Eddy> sensor is observing the operation of the turbo wheel" or at least that's how my poor understanding of grammar works.
I was only referencing to what I read here:
Just got a call from the service manager, Apparently there is a revised turbo that no longer has the exhaust temperature sensor and that an update to the car needs to be performed so that the car no longer takes these readings. This was their discrepancy when they weren't sure why it looked different then the one they removed. Would love some feedback on this... Also the car will get an alignment due the the subframe being dropped with the engine. And I requested it to be waxed! ; )
Okay that actually makes a lot of sense, one of the forum members posted that a revised Turbo charger was showing on the Infiniti parts page when he was skimming through it, it's good to hear they are going to do the alignment (and hopefully waxed!).
Sounds like they are making some progress at long last.
