APR v2.2 occasionally going into limp mode

[Arin@APR]

So past 2 days it's been in the 20's at night and in the morning I get an imediate EPC light as soon as the car turns on. A few weeks back I switched to the stock map for a week or so and still got it. Not so sure its even the APR tune. Any Giac, Revo, or stock guys experiencing this?

You're now getting this in the stock map too?

[apexit1]

yea i can try and make a video one morning switching to stock map and then turning it on. Of course with my luck nothing will happen

stock map on a flashed ECU is likely not the same as a reflash to stock. I went back to stock for 3 weeks in cool weather and had no issues. The first cold start (parked in work garage in ~40-45* weather all day and instant EPC. Going to reflash to stock when I get a chance and try to repeat but I'd wager good money it won't happen on a reflash to stock.

Interesting, Time to change the title of this thread!

[Arin@APR]

Cold start had nothing to do with it. I just had a report from a customer getting cold start reenabled - nothing changed. Looking into it further at the moment.

[staticuxo]

i'm very curious about this as i recently traded in my B8 for a B8.5 and will be looking to go stage 2 in the near future.

swank, easy to say just re flash this reflash that. half hour of labor at my shop is 50 never mind the time. Took me like 4 weeks just to find the time to go. I'd prefer something more scientific rather than shooting the dark.

The shouldn't be charging you for doing all this. It should be on their or APR's dime. They can keep track of it, but until they can prove that it's not their tune, I wouldn't charge you. You flat out said it doesn't happen on stock tune or calibration. WTF else can it be. Hey, maybe I'm wrong, but whatever. Arin's "searching" for an answer but he's been doing that for a while and still nothing yet. I'm making conversation... not like he's going to follow what I said anyway. Remember, I'm the guy shooting in the dark and not knowing what I'm talking about.


All I know is this... there's a reason why I haven't flashed my car with anything yet. The last car I had was flashed at 10k miles and I sold it at over 100k miles. For all those miles, not a single peep out of it. Engine was strong, no bullshit CELs about anything and it was trouble-free. It seems around here not everyone with OTS flashes for anyone is CEL or EPC light free 100% of the time for years on end. That's all...

[Arin@APR]

He said he can repeat it on the stock tune.

Actually, I haven't. I was waiting to hear back from people.

[saxon]

I tthink Arinn is doing the right thing and truly trying to fix this

What I think part of the problem is the fact the customer had to pay for flash back to stock or a modified file....

Apr is supposed to be the King of audi so make a solution that allows customers to have control, even if it's not a full tuning suite allow some end user adjustability or power to flash back to stock

[Arin@APR]

I guess I should have stuck with my first response on page one.

All I can say is I hate when people speculate so much.

[apexit1]

Arin INSISTS it's the very same map audi gives your specific car. They save it to their data base before the flash is even loaded to the car.

[paul]

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.

[apexit1]

When Arin and I first got in touch I looked at my post history. I think it was like march '12 that I made the first mention of EPC on the forums. Started off happening occassionally and slowly got to where I am now, I can count on there being a light when I start the car.

[paul]

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.

[apexit1]

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!

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.

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.

[sirsycott]

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

[apexit1]

great news arin, thanks for the update

[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! : )

[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.

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?
