Took my car in for rough idle...

[Scarpa]

Sorry to piggyback but I'm looking for the '15 TSB for rough idle. I keep throwing a P000C CEL and it usually correlates with rough idle. Car goes into limp mode for a bit, then it clears itself within 30 miles or so. It's happened enough times that I can predict it when I start seeing the idle go wonky. I've only had the car for a few weeks and am looking to take it into the dealer as soon as I start a new job that I can commute to on my bike.

Can someone please point me at the '15 TSB for rough idle so I can do some research before taking it in? I did check the TSB thread but the link on the front page is for '13 models and I read through the last few pages from '15 on and don't see an updated TSB

I'm just saying to ignore TSB from 2013-2015 and look at your problem as unique.

The more you stick to using previous TSB as guidance, the more you can overlook other, more realistic sources of problems on your car.... but keep insisting on Jalopnic and prior year TSBs as your backup info, and you'll kind of get nowhere fast on diagnosing your problem.

Good luck.

Well homie, sorry I made you upset with all this.

And I can't help but use prior years as a point of reference when all three prior years had the exact same problem. Counterspace Garage even described and posted a video of my exact problem on this forum.

It's the same issue this car has had for three prior years.

Yes, and you are putting dealership(s) in a bind if you use that as basis.

TSB is only useful for the technician to use when it applies to specific VIN that it references. Otherwise, Subaru will just view your case as an individual isolated case of "bad idle" and go from there to diagnose it.

You can reference a TSB all you want, but at the end of the day the dealership can't use that TSB to actually write up a work order, nor use it to perform any repair work. They can write it up almost word for word, but the actual TSB itself can't be used because it doesn't apply to your car.

Just call Toyota first. Mine was out off the year for reflash ECU, I called Toyota, they told me some vehicles post-ECU TSB still had the old ECU software. They called dealership, 20min later I had my ecu reflashed.

OK, here's what my invoice said for my "hesitation" problem:

"Found TSB reprogram for this concern. Out of calibration. Reprogram ECU. TSB0021-15.4"

I don't know if this will help any of you out, but I hope it might send you in the right direction. Again, this is for my 2015 Scion FR-S automatic transmission. Good luck!

I've already said that's not what I'm doing. All I'm doing is exactly what you said to do which is take it to them and tell them what it's doing. I politely told you that a few posts back but you decided to keep at it.

I don't care how it gets fixed. I'm also not the one who will be diagnosing it. On MY end, I can't help but notice how my issue is eerily similar to the issues from 2012. On THEIR end, I couldn't care less how they fix it.

My OP was mainly about how my dealership says they've never heard of this car having any idling issues whatsoever when that's clearly a lie, and if it's not then they're a Subaru dealership with their head in the sand.

This car (to them) could mean 2016 BRZ.

This car (to you) could mean 2013 - 2016 BRZ/FRS/86 worldwide.

The dealership being 1) fully aware of TSB, 2) never experiencing specific customer issues with idle out of cars sold at their dealership, and 3) not having issues on MY 2016 is entirely possible. Just because there's a TSB for a car doesn't mean the TSB will actually be used...

Another example is the taillight condensation issue and the TSB issued for 2013 model year cars. My car was serviced using this. I've heard of 2014+ cars with the same issue, even after the supposed manufacturer fix was put in place at the factory. Those cars were fixed using the same method, but the key part is that the TSB was not used as a means of justifying the warranty reimbursement between dealer and corporate.

As someone else already referenced:

"The reason they don't see any TSBs is because the TSB only applies to 2013 and early 2014 cars. The fixes outlined in the TSBs are already applied to all 2015 and newer cars so they won't find one for your car."

So to say that the dealer is lying based on 3 years prior cars w/ TSB and Jalopnik is all types of wrong information being tossed around... all I am doing is getting people to understand is that if there's no TSB for your car, you can't use a previous model year's TSB as a fix for your car. Conversely, if you have a TSB that may apply to your car and there's no issues, the TSB is useless.

People misunderstand what the purpose of a TSB is and throw it around like it's a fix or solution. Plenty of cases have popped up where a TSB really didn't fix the warranty issue at hand.
