just found out that my car is TD1

[Roccorace]

I just bought an s7 3 weeks ago and took it into the dealer to have it checked out and serviced. It is a 2014 with 26000 miles on it and the service tech just informed me that the car is TD1.

The question really is, on these cars how much of a panic attack should I be having right now? In addition do I have any recourse on the dealer that sold it to me who specifically cited that the car was not TD1? Finally, and I'm pretty positive I know the answer to this, is there any means of eliminating the TD 1 code by working with Audi USA?

You bought it from an audi dealer... but it wasn't CPO, but they made reference to it being NOT TD1? Am I understanding this properly?

If it wasn't an audi dealer, how would they know?

[agent47]

If it was an Audi dealer and you have paper trails where they mentioned it is not td1, you need a 'conversation' with the dealer. If they dont help, contact AoA Corporate. I do think there was a bulleting out where the code can be removed after AoA authorized ECU flash to stock by the dealer. However, if it was a non-Audi dealer, AoA wont be of much help. If the dealer doesnt help, legal recourse is the only option.

Tough situation. While logically I'd think you should have recourse, given that you have it in writing, it's possible the car may not have not been plugged into Audi's computer/service system while in inventory (or prior to that), and thus the TD1 flag may have just recently appeared when you took it in for service- in which case it will be hard to prove any wrongdoing on their part.

I've seen an internal document stating that TD1 flag may be removed if the vehicle is returned to stock (I think this is done automatically by the computer).

Did you happen to buy this car from Chicago? In particular a VW dealer? I was looking for a White S7 with similar mileage and the TD1 was the first thing that made me avoid the car. Sorry to say this but you should have checked the VIN with an Audi Dealer or another dealer. An Audi without a warranty isn't the end of the world but, from my experience, an out of warranty car repairs end up costing you a lot of $$$$$$.

your car being TD1 can be an easy fix get the dealer to buy a new ecu, it is 2500 and it will clear the td1 and allow you to get all warranty work covered, this will be a new sealed ecu. You can go a step farther and buy your new ecu get a tuner to immo defeat the old ecu and then you can have two ecus so you can swap your tuned ecu out for a stock one at a wimb....

[Sd76]

So td1 basically states that there are aftermarket modifications in your car that void warranty in your car???? I'm not familiar but will google. Are these significant mods like tweaking engine exhaust or as simple as coilovers and wheels. Thanks.

I am also hearing this as well. I think there has been a shift in the way they are dealing with TD1, at least at some dealers.

Immo defeat/off does not work on these ECUs (BOSCH MED 17). The only option is a complete clone. And even then, if the TCU (which is not part of the ECU) or any of the other thousand electrical parts are communicated any info about the 'flashed' ECU and stores it, which it probably does (e.g. a "black box"), then you're still screwed. Far too expensive to possibly still be flagged with TD1, or flagged upon manual review which will happen if you need a significant repair done.

I was putting it in simple terms, Audi has done warranty work for me with this system in the past with no issues, I can only speak from what has worked for me in the past.

TD1 is technically any modification to the engine- but automatic flag only occurs when you have a performance tune . However , even with a simple intake, the tech can manually flag TD1 if he wants to be an asshat.

I do know it was easier probably 10months ago . We could just tell them not to scan the car and it would be ok with them. But now, some dealerships outright deny service if you ask them not to scan. So you really need a very good relationship with rhe service guys to get by. I , for an examply, know the shop foreman at a dealership nearby pretty well. He made sure the car was never scanned. But one tech hooked the car up without the foreman guy knowing. The inevitable happened. Lol. But yes, the internal document does say the flag can be removed after AoA authorizes them to flash the ecu back to stock.

To OP, lets start from the beginning. You bought it from what dealer? Audi? CPO?

[HeelBuff]

I've yet to read about any significant warranty claims on the 4.0TT, with or without a tune. While it's bullshit you got lied to and I hope you get the dealer to own up to this fact, it's probably not the end of the world either way.

[Brooklyn]

My car isn't TD1, but just to give you a flavor of the asspain involved...when I bought my car back in February, the check engine light came on within days of buying the car. It happened after a fill-up, so I gave it a couple of days and it eventually went away. A few weeks later it came back on. Bought a vagcom, pulled the code, and eventually mentioned it to the dealer at my 25k. Got the usual bullshit "could not duplicate" nonsense. It went away for about 10k miles and in that time I got the car tuned, added exhaust, etc. Now the issue has resurfaced. Gracious Audi shop owner here gave me a pretty solid explanation. Sent the dealer a copy of the code and the analysis and asked them whether they had seen this before, possible causes, and whether they would need me to return to the stock tune. Tech's response via the Service Advisor - "It's probably because of the tune." TD1 is a potentially monumental pain. I'm hopeful APR and GIAC see the light and start offering something similar to what Unitronic has done in allowing folks to flash back/forth on their own, rather than having to pay a frigging "authorized dealer" $100 plus each time this needs to be done, because unless you're Daddy Warbucks, you should seriously think twice about risking that flag if you can avoid it. OP, not sure you have much recourse. Did the tech say what caused the flag to be applied?

The tunes are very reliable. I did not face any issues on my 3.0T either for the 25k miles that I had the tune on my car. The engine mounts gave out on my car but after a little talk, they replaced those under warranty.
@Brooklyn - so since you had already mentioned it to the dealer, did they fix the issue for you under warranty? Also, uniconnect is going to he a big hit if it works good. EPL has done the same for B8S4 and people switched to them in hoards. Flash from home is a great tool for people who are not close to the dealers plus when the dealer wants to charge you everytime you go in.

What should really chap the OP's loins is if it's flagged TD1 and it doesn't have the extra ponies.

[Brooklyn]

Just got that response from them on Friday brother. My only comms with them since then was to point out that the problem pre-dates the tune. This particular dealer is new to me. Have only used them for the 35k. May take it back to my original dealer and point out that it's come back. Either way though, I suspect I'll be flashing back to stock shortly.

So how do you find out if the used Audi you are buying has been flagged TD1? Can you find out from other than the Audi dealer? It seems to me that the OP could come back at the seller for misrepresentation (assuming it's a dealer and they indicated it was still under warranty)

[sciblades]

just so every one knows when you are flagged with td1 you still get audi care service and such things the only things that become an issue is major warranty work, If your dealer is willing to work with you typically they can call the regional rep and override the td1 issue and still get the work done. If your service advisor is not willing to go to bat with you just get on the phone to Audi of America they will make it right you just bought a very expensive car.

[SunDevil]

Some thoughts:

1. If original dealership not Audi .... OP could be SOL. Again ... hindsight would have been to investigate the VIN prior to purchase. But even then ... the car could have been modified after it's visit to a dealership capable of detecting the TD1.

2. I've modified and applied tunes to many of my cars in the past. I did so knowing FULL WELL that I would be on the hook for any related issues. Pay to play ... as they say. If you tune .... I wouldn't expect that a dealership or AoA would go to bat for you.

3. If I bought a used car that was flagged TD1. I would be livid. Some are saying just change out the ECU and everything will be fine. I don't agree. Regardless of what anecdotal evidence you may have .... the aftermarket tune or modication "may have" exacted a higher amount of stress on the car.

4. I have no issues with mods or tunes ... as long as I know what they are and who installed them. OP didn't have this option apparently.

I am in fact asking for help. Qualifying that I'm not useless in the space shouldn't be offensive...

I was hoping for someone to say that they were incorrect at the dealer, which having worked at dealers throughout college I know that they often are - especially around matters of modification.

If my response came off as unappreciative, I apologize - I was just trying to get deeper on the subject. I came to the forum for help on this and respect opinions and facts from enthusiasts.

Not CPO. VW dealer sister store to Audi dealer offended by same group.

It has an intake and full Milltek exhaust with cat delete. For that reason it also has a tune but dealer specified it was not black listed td1.

Tech couldn't tell. Just came up when he logged the car in.

I went in my Audi dealer, checked the car in and as soon as he put in the vin he saw the TD1. Not a fun moment.

The original dealer is part of a small chain of dealers including Audi. The sales manager when prompted about the car stated "we had the car run through it Audi dealer and it checks out great, it is not black listed for any reason". Hind sight being 20/20 I should have driven it to the dealer. Carfax doesn't show this as an issue - kind of think they should.

Tune and run 10s

[rottley]

Is possible that the OP's car became TDI'ed when it was hooked up to the system to see if it was?
Just a thought.

When I buy a used car, I don't believe every single word form the seller (person or dealer). I realize there is some risk in not buying new.
Like when I wait for the check engine light to go off, then rush over to carmax to trade the car in.

[pandi]

My dumb question -- what else could have been done to the car other than a prior tune which would have resulted in the TD1?

[DB22]

OP - you haven't stated if the car has a tune or not, you have only stated that it has been flagged TD1.
When VW took it to Audi before selling it they may not have checked for a TD1, they probably drove it, visually inspected it and recycled it.

[Serpent]

OP said audi dealer ran the vin and told him it was TD1. So i'm guessing car was already TD1 when OP bought it.

I went in my Audi dealer, checked the car in and as soon as he put in the vin he saw the TD1.

[agent47]

Per what I get from the OP- the car had a tune, catless exhaust from the get go at the time of purchase. The VW dealer said it is not flagged. Now the OP went to an Audi dealer who just "ran" his VIN through the system and it showed the flag.
To the OP @Roccorace- they just ran your VIN and had not connected your car to their systems, right?

It seems to me, though maybe I'm oversimplifying, that there are two possible courses here:

1) If the selling dealer represented the car 'As Is/No Warranty', then you're kind of SOL. Though, as others have stated, unless they can prove your modifications caused the issue, the warranty must still be honored by Audi.

2) If the selling dealer represented the car as being under the manufacturers warranty, and not As Is, then you go straight back to the dealer with the law on your side letting them know they misrepresented the vehicle. The laws in pretty much every state regarding warranty and used cars are designed to protect the consumer. Either get your money back or come to some other satisfactory resolution.

[subterFUSE]

Carfax doesn't show this as an issue - kind of think they should.

Carfax is pretty much useless.

I had a new Lexus stolen, involved in a high-speed police pursuit and then crashed into a parking garage. Suspect escaped police on foot. Car impounded. Wrecked pretty good, too.

Got the car repaired by a good body shop. 7 years later, sold the car privately. Ran my own Carfax report just for kicks.... nothing on it. Totally clean report. No mention of the theft or repairs.

You are so right with this one. Not being able to flash these things is pretty pathetic. My closest APR dealer is a 2 hour drive and it is a royal PIA!
