Definitive answer on getting TD1 flagging after flashing back to stock...

[Innovator]

No, I don't have a definitive answer, but I'd like one. Does anybody know for sure if flashing back to full stock will prevent TD1 status?

[13S4]

1) Please only people with S4's Answer....

2) The real question should be if you've had repairs done after flashing back to stock. This would mean they would actually scan your vehicle, and note that it is fine. Not having the flag after an oil change doesn't guarantee you will be covered when you need it.

To answer OP, I have had two services done (CEL/Ebrake light, scan showed passenger seat airbag sensor bad and oil consumption update) after being flashed back to stock. I have not been flagged TD1. That does not mean that AoA will not figure out a different way to run the scan in the future and check a different way for ECU changes.

13S4, Yes, I have an A4, so there might be a different answer, but I don't see why I flash back to stock on the A4 would really yield a different answer than the S4.

The long EPC thread indicates that flashing back to stock is detectable. He however was flagged as "T23". There have been a couple of other thread that also indicate that flashing back to stock after ECU tampering is detectable. I would love to hear from others that have gotten service say after April 1st when this got more attention.

Before someone freaks out I'll say to do a quick search. I asked the same and learned within an hour of reading dozens of threads.

The ECU has to be opened to be flashed. If they wanted to, they could just look at the ECU and see that the seal was broken. Dead giveaway.

jesus, another thread on this [facepalm]


NO

Seriously Innovator. That's worse than "whats a TD1" post. [facepalm] At least noobs don't know any better.

I just posted in the other thread and like I said there, this will be my only post on this thread.

True. For sure. You must take your pulley off too if you have one, careful not to bake the paint on your stock pulley or mar it when putting it back on. Take anything easy to remove off the car and go back to stock. If you have the will, make the whole car stock if you have the time and the dealer issue is important enough. Make sure you don't leave telltale marks on bolts, CLEAN YOUR TOOLS before and during work on your car. Make sure you aren't missing any bolts and replace the ones that look wrenched. Order new shear bolts for the ECU chastity belt and put it back on, if you had one in the first place. And when they ask you, 'is your car flashed?', they will usually say 'chipped', say 'no', and nothing else. Practice this in the mirror or with a friend if you can't keep a straight face. Most can't. If you can't, and be honest with yourself, get your wife to drive the car in, they likely won't ask her. Seriously.

Got it? Okay.

EDIT:

Even if your flash count is greater than zero, if you present to them a stock car, and do not crumble under questions from them, you will be fine. It's the finer details that usually matter (see above) and can give them evidence to present back to you and then ask if you've been tuned.

You will compromise your credibility severely if your small pulley is STILL on the car, or if you leave the APR ECMS manual and authorization code in the glovebox, timeslips from the strip in the armrest, missing chastity belt or one that has dremelled bolts (new shear bolts are cheap), etc.

Clear your codes too. Any stored fault can and will show parameters outside of stock, but there is NO OTHER mystery log. It is within your right to clear your codes, you can simply say you let a friend do it.

Do NOT leave your VCDS cable in the car, and do NOT chat about your VCDS mods - reverse them if you've done any.

This is very much like anything else in life - if you are lazy or careless, or simply just feel entitled and think you shouldn't have to put in the effort, you will lose.

The answer is really simple. Look at the cars ECU as a computer. Anything that you do to it will be logged somewhere. APR even said themselves in one of the threads that even if it was flashed back to stock it is detectable that it was done.
The definitive answer is yes it is detectable no matter what you do.

How the F is an hour a "quick" search? I PM'd a few people who have asked to be unnamed here (which makes perfect sense), and NO, Audi cannot detect if the car has been reflashed back to stock. Major drivetrain service work has been done with no flag.

This is the same in the Corvette world as well. If you go back to a completely stock BIN, they cannot deny service for having been tuned.

Now the cat and mouse game can go on forever just like any other form of security, but as long as you only play the game when the hackers have the upper hand, you'll be fine, you just don't want to be the person who finds out the cat has taken control again.

[cNEGOTIATOR]

Previous answered were great, thank you guys. Was just wondering if there are any updates or changes to this info? Anyone flashed back to stock and have been flagged ever since?
