APR v2.2 occasionally going into limp mode

[SwankPeRFection]

Not saying that the map is different, but the content on the ECU differs... 1 program vs 3-4 programs. I'm speculating of course but I haven't ever tripped this code until I flashed first with 2.1, then with the cold start delete 2.2, and now the cold start re-enabled 2.2.

Does this mean you had no issues while on 2.1 version? If so and the new flash you have now is just a revised 2.2, then something else was introduced in 2.2 along with cold start delete that could be doing it. They should have flashed you back to 2.1 NOT an edited 2.2.

2.1 had the problem... 2.2 had the problem and the latest 2.2 has the problem. No issue on stock reflash that I encountered. Car was stock 9 months since I originally purchased it. Flash and cold weather has the start up limp mode issue.

OK, cool. Thanks for clarifying that.

so last night after work I tried to get the EPC straight from start up and got nothing. It had been parked in ~30* weather for about 8 hours. This morning the temp gauge said 20* and it had been parked in that for about 13 hours. Nothing right at start up but when I turned the wheel the EPC light came on, never touched the throttle. I switch to stock map before turning the car on. Arin PM me if you want my VIN again to confirm map one is stock. Programs should be stock, 93, 100, 104.

When you park and change maps, have you ever tried it with the steering wheel perfectly centered and not cocked to one side. Also, after you key on and change maps, have you tried turning key off and then starting the car as normal after that last cycle? It may not be necessary, but I always make it a habit of cycling the ignition like that whenever I make changes with VAGCOM, so if I was APR'd, I'd make the changes and then do one final cycle so that when it's key'd on, the ECU starts up fresh already under the right program as opposed to booting up in one program and then changing programs and then not rebooting again under the new program. Hope this makes sense as to what I'm trying to say.

[apexit1]

Pretty sure I got what you mean. When we spoke via PM a while back I was on the stock map for a week or so and had gotten it a few times in the time.

[Arin@APR]

I spoke to engineering about the code a little further and they've traced back conditions that can throw it. It's pretty tricky and should only happen a really low load levels. We'll be looking into this a little more next week and hopefully we can get a solution pumped out soon.

Thank you!

[apexit1]

great news arin, thanks for the update

Why didn't it happen in 2.1? Were there other calibrations made to 2.2 aside from the cold start disable?

2.1 had the problem...

Swank, I appreciate the outside help but please let us diagnose this properly on our own.

don't worry , APR will give it's customers v2.3 soon along with more horse power.... just like the non-existant FSI K04 v2.0 file that was promised on golfmkv.com

Hey, I'm one who likes to know the details behind the problem and the fix. I'm not one of the people on here who are just fine with you saying "Oh, don't worry about what it was, it's fixed now." But then again, at first you were like "Oh, this isn't a problem with our software because it doesn't happen on my car." Well, obviously it is, so why does it happen, is it really tied to colder weather conditions, and if it is due to "low load conditions" as you put it, why did it still go off when the engine wasn't running and the steering wheel was just turned as it was posted in that video? Yes, enquiring minds wants to know. It's interesting, that's why I'm all questions. Cuz I'm curious.

You aren't paying for their intellectual property, but you are paying for their off the shelf tune.
I honestly think that Arin gives out quite a bit of information on 'good faith', and I don't think he owes you anything but to fix the issue and say "Here, it's fixed now."
If you don't like that, then you are in a tough spot and either need to start working for APR, or make your own tuning company so that you can change things yourself. I am sure one day something like Maestro will come out for this vehicle, but I think that day is a long ways away (5+years).


^ Don't take that the wrong way, it just seems like you feel Arin owes you all the information APR has gathered, and from a third person standpoint, I just thought I'd let you know that it doesn't look like he does.

[paul]

why did it still go off when the engine wasn't running and the steering wheel was just turned as it was posted in that video?

Swank I'm not defending APR here or anything but in the video the engine was on... the steering wheel is power assist/hydraulic and will put a load on the engine when in use. The same is true with the brakes. once the EPC / Limp kicks in, it's like the car doesn't have control of the throttle body to maintain RPM. If you steer or hit the brakes, the RPMs drop in limp which is what I'm guessing triggered apexit's EPC with the steering change.

Swank,

You're not helping and you're making everything worse. Please stop. I want to help my customers, not argue with you. I don't appreciate you making up lies by falsely quoting me either.

[paul]

Arin can you please let me know when the next version is out I'll work with my shop to get flashed to test it.

[Arin@APR]

Yes Paul. I'll keep you and everyone updated. Thank you! : )

[SwankPeRFection]

Nothing. It doesn't do it on my car, and no customers have reported back on files with cold start enabled.

Swank,

You're not helping and you're making everything worse. Please stop. I want to help my customers, not argue with you. I don't appreciate you making up lies by falsely quoting me either.

No one is misquoting you. You said yours isn't doing it. Other posts you made also lead to the understanding that this was probably something else causing it. It's in this thread or another about the same issue. I'm not going to go dig it up just to remind you of what you said, but you did kind of shrug it off until a bunch of people raised their hand about the problem that's supposedly been happening for a while but not brought to your attention for some strange reason. I guess people just dealt with it.

[Arin@APR]

No one is misquoting you.

Swank, you ARE misquoting me.

Here is the misquote, all from this thread:

But then again, at first you were like "Oh, this isn't a problem with our software because it doesn't happen on my car."

Here is what I said. First, in an attempt to help out I suggested switching back to stock. If the problem stays it's probably hardware. If the problem goes away, it may be our software.

Let me say that last part again.

If the problem goes away, it may be our software.

I have nothing to hide. I want to help. If there's a problem, I want to fix it. Period.

...I would expect moving to stock mode would result in it staying if it's hardware or going away if it's software...

And later when you asked me what I've found out so far, I responded with this:

Nothing. It doesn't do it on my car, and no customers have reported back on files with cold start enabled.

So again, please stop misquoting me and stop acting as if I'm shrugging off our customers.

[integroid]

Dang swank, go away and let them fix it. They are obviously trying to help their customers and you are obviously trolling and trying to bring them down. We get it...you dont like APR. Can we just move on?

[apexit1]

Wonder if swank really has an agenda or is one of those awkward people

[chevelle71]

Today was very cold and my car did not want to start with the 93 tune. I put it on stock mode and it started without any problems. I think i'm going to stay stock until this cold weather problem gets resolved.

[adbender]

Thanks for responding to this Arin.

Im staying in stock mode for time being too....

I will miss the TQ but it may also keep my car out of the ditch.

Are you getting it while driving? I only get it in the first few seconds of startup. Given like a minute of so and I have no issues.

[saxon]

I think they meant that not having the extra power will keep them out of the ditch

[Arin@APR]

I'm not sure if this will help at all, but I'd like to collect some more data for engineering over the weekend, just I case it helps them at all. Let me know the following:

Vehicle model year
Transmission
Ecu box code
Ecu revision
APR stage
APR version
APR octane
Pulley
Intake (note style, like open or closed filter)
Exhaust catback section
Exhaust catalyst section
Exhaust header section
Exhaust o2 sensor spacers used?

I think that should do it. I don't think there are any other mods that would really alter airflow.

Thank you guys!

[apexit1]

via PM on on here? How do we know the ecu box code?

Update: We tried something up North at one of our dealers and it worked. I'd like to give it a day or so more testing before assuming it's corrected and releasing an update.

[Deckdout2]

Looking forward to it. Getting more annoying as it gets colder here in North Kakalaky.....

[ILL3ST]

Hope it all works out

out of curiosity, do these kind of updates get rolled out across the other 3.0tfsi platform's tunes like a b8.5 s4, c7, or 3.0 q5.
I'd imagine there are a lot fewer stage 2 Q5's than s4's and even fewer that would be in the same cold conditions to experience this issue so may not get flagged as an issue but potential customers from the “polar vortex” (myself) might bit unclear if they are getting all the “learnings”

[Arin@APR]

If it's a global change that would be an issue on other models, we'll usually issue a change to everything.

[adbender]

great news Arin...

So on my way in I got the pleasure of experiencing my car go into limp mode again…….this time on the highway……at 70mph. Caught off guard for sure, had to coast to the side 3 lanes over through traffic and shut her down and restart. This can not keep happening, and was the first time it's happened on the highway like that. I "dealt" with it in the mornings when my car was cold, so I just got use to expecting it. While I'm driving at any rate of speed for it to do that is a big no no, and obviously not safe.

Arin - Can you tell me how close we are to a solution on this?

Scan it and see if it's the same code just to make sure it's not something else. I've never had it occur outside of the initial minute or two.

This. Make sure it isn't a different problem. May not be tune-related at all.

Arin,
On Jan. 2 GMP Performance in Charlotte NC did an APR pulley and ECU upgrade on my 2014 S4. Zero problems so far, about 400 miles on the work.
