ECM Software Recall 2016-09-21

[SwankP3RF3ct10n]

My B8 doesn't have this listed per that Audi site lookup tool. Just FYI.

[Mat@1975]

Got my car back, I did noticed that my car runs hotter after the ECM update. Before it usually at around 202F, today it reaches 215F..driving condition is the same. I meant engine oil temperature.

Hello,

Right ! I also noticed this rise in oïl temp after 24CO.
However, i would not be too concerned about this because it's the dash displayed oïl temp, which is, in my opinion, not a mesured oïl temperature (see in VCDS/Vag Com, the label is "calculated oïl temperature").
Maybe the changes afected how oïl temp is estimated, but not real oïl temp. Furthermore, i think that our oïl loop is not regulated in any way, so i don't see how software could allow for oïl temp changes.
Lastly, if this temp rise is real, i don't see it as a concern, since it could fight carbon build up in a more effective way.

What do you think guys ??


Best regards,

Mat

I just picked my car up after they did the update. All the vag mods are still there.
It's like you flash your car, the vag mods don't get changed.

Just a heads up that this wasn't the case with me. I keep noticing more and more vagcom mods that are gone.

- Windows up/down with remote
- Lap Timer / Oil temp
- Steering assist disable

I'm sure there are more I haven't noticed, yet.

VIM stayed intact, as did no warnings when inputting GPS address while moving. Also the gear display stayed intact. (S1, S2, D1, D2, etc)

For what it's worth , when they updated the climate control module on my wifes Q5, it erased every single VagCom mod we had in place.

She was not happy. But it's an excuse for me to buy my own VAGCom and not borrow a friends. :)

Another important note is for all of us living in California. If you read the back of the notice it says this update is REQUIRED for all people in CA and you need to submit proof to the DMV to get your registration. So I guess I have to do it eventually. Hopefully it doesn't screw up flashing back to APR Stage 2 after the new software is installed.

this is usually based on the dealer tech that runs through the modules on your car when it's hooked up
the VAS tool will give them popups for every module it scans and say "incorrect factory coding" "re-adjust to defaults?" if they click yes, you lose your vagcom mods for whatever module it was in

i usually ask the service adviser to kindly remind the service technician to skip the scan altogether, if it's unavoidable, i just ask him not to change revert the coding for specific modules

2nd that.

Just get the carista app.. and redo the Vag options with simple yes and no clicks

What OBD2 device are you using with it? Does it work with other BT OBD2 devices or just the native one?

[Tanner]

I've had this one for probably three years now at least initially for the torque app. No issues with the Carista app.

[bmoreS4]

So you can use BT or wifi adapters with it?

I bit the bullet myself and ordered the Carista OBD2 adapter of amazon for $39.99. maybe could've saved a few bucks, but since ill likely use the carista app, figured I may as well have their hardware. probably not necessary.

Good advice. Thanks.

Was at the dealer today for the 35K service. They wanted to do the update. I asked if the update would wipe out my Vag mods like the one's you have.
The SA asked the tech who works on my car. They said it would definitely wipe them out. I declined the update.

No they are not, I can still see engine oil temp after this update. Certain update did wipe out them though.

Thanks for the info! I'm not too concern about it either :) It helps burn out all those moisture and gas in motor oil if it did increase anyway.

[Sean@APR]

Im going to go APR stage 1 tomorrow. Do you think this update might interfere with flashing to stage 1?

i received this update last week.

You're in the states, so it shouldn't be an issue. When they update the file, we extract one and build the performance file, no big deal.

Mat, who did you talk to over there? I don't recall hearing about this from the EU.

Hello Sean,

Thanks for geting involved. I will answerd you by MP

So my check engine light actually went off for this very reason at the track last month....it turned itself off randomly the next day but when I did a VCDS fault code check it was for this issue. I have a Stage 2 tune, do I risk bringing it in? Or not worry about it

[jygesq]

add me to the recall 2015 S4 . It showed up on my audi page, Confirmed with AOA and dealer. Appointment Saturday AM 1 1/2 hours
car is bone stock except for dipstick upgrade. No written notification from Audi yet

[Hy Octane]

Just FYI.. If the dealer does flag your car with a TD1 you might not know about it for weeks or until you go in for any warranty repair.. The mechanics dont always know what is found by the scan immediately as the results go to a server out there somewhere and floats around until somebody sees it and enters it into the system. Anyway, if you have reverted to stock for this update, the tune company will have to update their files before it can be reapplied to your car.

[FWP!]

Got the notice in the mail the other day, I'll get it scheduled for next week.

Tune company as in APR or the dealer that does the tune? So to get re-flashed back they need an update from APR?

[waxxonMTL]

got the letter.. from what i can see. this update brings me nothing good just potential problems with TD1 or my tune. Or am i missing something here ? I will just ignore this recall. ( not to mention, i never got the warning and I don't need to pass an emission test over here)

I'm feeling the same way....are we really going to mess our cars up if we don't get this software update?

Thanks
Paolo

[wangshuo1989]

Update, I got another issue after getting this recall. My engine oil temp will fluctuate (like goes to 170 and immediately goes back to 168, then goes to 170 again, and it happens all the way to 200), that's something I've never seen before. Car drives normal though.

[Siopao]

Hey Wang,

So does that mean don't do it???

Thanks,
Paolo

[Dr GP]

Got this today for my 2014 6MT that I no longer have . It specifically states, IMPORTANT! Please note: that if the ECM in your vehicle has been "chipped," "tuned," or otherwise modified from original factory specifications with aftermarket components and/or software, work needed to repair, replace or return the ECM to original factory specifications is NOT covered under this action" Certain Model year 2102-2016 MY Audi 3.0L TFSI Engine Vehicles. So it would include both B8 and B8.5 cars

^ I Think everyone saw that on the pic of the letter

I haven't got the letter yet but I need it done. Im waiting too to see the outcome.

Hey Sean, I just got this recall letter in the mail a couple of days ago. I have APR Stage II tune. So, are your saying it's okay for me to flash back to stock, do the ECM update, and then flash my Stage II back without any issue? Thx!

[yeuchau]

Just FYI, for those that concerns about flashing back to stage 2, I had no issue on this.
Flash back to GIAC stage 2 without any issues.

[FWP!]

I'm really confused as to how this update would affect oil temps. Maybe they have leaned out the a/f mixture some, causing higher EGT's and a warmer engine overall?

Agreed ,,it's supposed to do with diagnostic thresholds for the cats. Maybe the temp stays the same but is being calculated differently.

I'll put more miles on it and see if it goes away. If not, I wish I didn't do this update...

That's a possibility, can someone log their car please and post?

That's good to know! After reading Mat@1975 post about his issue, I was a little concerned.

This worries me. Sounds like the programming change is substantial and may affect performance. If it were just a change of a threshold to a more permissive value, why would DMV care? The fact that some people see higher oil temperatures after the ECU update, if true, confirms that the programming change affects engine operation significantly.

Because it has to do with the emissions system in the car and we all know how Cali is about them apples.

A catback and intake shouldn't be a problem?
