Something's not right here and I'm hoping to find an answer. I just noticed today while waiting in the parking lot for my wife, with the car on my idle RPM was at 0. Yes, zero. Car feels fine, no issues at all with the car vibrating or shaking like some people have wrote about who has had idling questions. However, those threads never mentioned idling at zero RPM either.

Any else experience this issue? See the attached picture, and yes the car is turned on!

Thanks,
Erik

 

Never seen this before. Does the car drive normally as well? When you come to a full stop does it go straight back to zero? Maybe you can try resetting your ECU see if that solves anything.

 

Does the needle move during normal driving? You probably need the gauge cluster replaced, which is a warranty issue.

 

wow. Idle at 0 RPM. You just got the finest motor from the future which saves lots of gas.
hehehe
just kidding. If your gauge still reading the correct rpm while driving then maybe the reading is wrong at low rpm (probably caused by software). In the case that the needle doesn't move at all, maybe the signal wire got loose or shot at some point.
Good luck.

 

Interesting...Seems like I'm the only one having this kinda of a issue. FYI the needle moves just fine when the car is moving. The needle drops to 0 when I come to a complete stop when in Drive or in Neutral. I'm out of my warranty period, but I'm hoping that my dealer will take care of what it is due to the low mileage of the car, and my loyalty to the dealer which has taken care of the car since day 1.

I wonder if this is like BMW's start/stop technology in the M3 lol :-)

 

Your car's the prototype, they just didn't tell you lol

 

I dropped the car off this morning to have the dealer look into the issue. I just heard back and they informed me that they performed a ECU update. I was charged a diagnostic fee of $120. If this fixes the issue, then the $120 was well spent. If not, I'll be back at the dealer to complain!

 

$120 is a cheap fix, considering a new gauge cluster/labor would have been $$$$

 

got the car back and the RPM doesnt drop to zero any more. problem solved.

BUT! I noticed with the updated ECU the car feels a bit different, in a not so good way. It feels like I lost power with this flash, the car just doesn't seem to have the get-up-and-go feel to it like it did before the flash.

 

The car will eventually learn fueling trims, etc etc over a long period of driving. It should feel back to normal after a few hundred miles of driving.

 

Could be that the new flash updated the twitchy pedal feel we all know and love

 

It's good to hear. So it confirmed my thought that it could be software issue in the first place.
The ECU reflash meant to save gas and gives drivers smoother ride. I remember they came up with the ECU update on late 2008. I have that too and don't like it. The gas saving is non-noticeable.

 

All, thanks for the input.

Phalanx, I'm not aware of the ECU reflash's purpose, is it to solve my idle issue or what you said, save gas and give drivers a smoother ride? I'm a bit confused here. All my service advisor told me was that they confirmed my RPM did in fact drop to 0 when my car's engine is running and is completely stopped so they applied a ECU update to fix that. Does the reflash also tweak the gas and throttle sensitivity?

 

At the time I did my ECU reflash, it was for the throttle control, nothing more than that. I am not sure if they updated another version of the ECU. In your case, reflash the ECU is the first step in troubleshooting the idle issue. If that didn't work out, I bet they will try to replace a new instrument cluster. Those are troubleshooting protocol that they would do. But fortunately, reflashing the ECU fixed the problem

 

I'm sorry, but it seems like they pwned you

It was no need to do the throttle sensitivity ITB, as there is another service calibration procedure for the gauge needles (which should fix your problem). And they just flashed your ECU with the new revision of it (with the reduced sensitivity), which might had correct calibration for the needles...

And now, the only way to have your touchy throttle back is to do Uprev tune (or buy Sprintbooster).

p.s. I still miss mine throttle sensitivity, since I did this useless ITB (but soon going to tune )!
