Launch control stopped working

[audiblitz]

The Launch Control in my 2012 has stopped for the past month.....I have tried it many times and it won't work. I used to use it frequently.....

Put car in dynamic, press ESC button.... push brake pedal to the floor....push the gas pedal to the floor...it does not go into launch mode.......instead the car starts to lurch forward and loads up the transmission like a torque converter automatic.

I have the car warmed up, steering wheel straight, I have tried ESC off with one press and holding down to turn it off all the way. I used to use this A LOT so I'm pretty sure I'm not doing it wrong.

Does anybody know if there is a limit to the number of times that you can use launch control?

It may happen if you use it too many times in a row, I noticed on a track date once it happen I let the car cool down and waited about an hour it was back. May have been similar but now with the APR tune I havent had much functionality of it at all since then just only in stock mode. But of late I switched it to STOCK mode and still the LC wouldnt work I am wondering what is happening I have noticed it after my last service. Maybe they updated something hmm I have to look into this further.


I also noticed since my service I am unable to change maps on the car as well. Wondering what I will have to do about this.

Thanks for the info. The car is totally stock (I resisted the urge to flash somehow!) I just tried it again, drove the car around for 10 minutes...nicely...it shows its warmed up...then I tried every button combination....and different pressures on the pedals... I think Audi might have a built-in limit to the number of times you can launch it.

How many times have you used the L/C? (ballpark?)

[Kay15]

In my Stock mode, I must of used it about 25 times and it was still going

[USMC1488]

Try to unpulg the battery over night. Maybe it will reset a fault or whatever it is that is occuring. A long shot but still worth a try.

I would LOVE to know if saving channel 00 fixes this:

[Select]
[02 - Transmission]
[Adaptation - 10]
Channel 00
[Read]
[Save]
[Done, Go Back]

Also see if that resets group 30 in measuring blocks...

[Kay15]

Have no fear a TUNE IS NEAR!

[audiblitz]

A lot....like seriously a lot.... like hundreds of times... I can't be the only person who owns an Audi that does this though in the whole world?

I wanted a car with a warranty that i could DRIVE hard... no warranty and I might as well take a Mazda3 and rice it to 500hp!

hundreds of times???

[audiblitz]

hundreds of times???

Yes I got DSG instead of manual because I didn't want to pay for replacement clutches.

[caphie]

DSG clutches never need replaced?

I thought some people got 100k+ miles on DSGs.

[motionneon]

I'm guessing NOT if they launch it several hundred times.

[audiblitz]

So maybe the car has a built in limit to the number of times that you can launch it?

Possible that its a built in safety feature. Audi saying, "Okay, that's enough". That's my initial thought. I seem to remember reading a few years back on the forum that their may be a built in launch limit.

Perhaps...but if that was the case I think someone in the world would have hit the limit before me!

Maybe i should try unplugging the battery overnight.

What makes you think the automatic clutch is mechnically different than the manual clutch?

I'm kind of dumbfounded you thought that abusing the car like this would actually be covered under warranty should anything go wrong with it. It even specifically states that it wears out the transmission right where it describes launch control in the manual.

tl,dr; Audi won't cover your clutch packs should you have worn them out from using launch control.

Yea. I've done it probably 7 or 8 times but only to show off to friends. Seems obvious that it will accelerate wear on transmission/clutch/etc. BUT by programming that feature in it IS misleading to consumers.

Holy beat the shit out of your car, batman:

I dont know why there would be a limit on the number of times you can do it but launching it like that wears out components a lot faster. On my x5 there is a dedicated launch control but in the manual it warns you that any damage resulting from repeated use of L/C is not covered under warranty. I'd be careful because its all logged in there and they will use it against you if something goes wrong. Plus on the s4 doesn't the L/C not make it any faster? I'd just stop using it. on my M it definitely shaves a few tenths off to 60 but they were made to be launched often

Haha would have loved to be a fly on the wall: "OK, so we need to limit these launches...guys do you have any suggestions...ballpark....mmm....maybe 30, naw 50, naw how about hundreds of launches"

[GeoJoe]

How is this logged... does the S4 have a "black box" that records a variety of stats?

And how long is it logged for?

Could 'hundreds of launches" throw a TD1?

Personally, not a single time for me, just in case AOA is reading this...

block 30 in 02 as mentioned above

Probably until cleared but that is what I was asking for him to check above

lulz, I've seen some TD1 paranoia but this takes the cake!

I'm pretty sure farting in your car can trigger a TD1 these days.

Any update? My coworker hit the limit also. Think the counter max is 200!

[dparm]

Hundreds of launch control uses? Reminds me never to buy a car from you, nor to loan you any of mine.





Also, the guys who frequent the drag strip have demonstrated that LC is no faster than just mashing the gas pedal.

Check to see if there are any codes in the mechatronic, suspension, ABS. If there are fault codes, it can disable it.

Does he have vagcom to verify?

How do I access that info? My car is CPO so I'm interested to see how many LC's if any it's done. I haven't done any myself.

[S4charged]

Can't believe there actually is a limit. Interesting..

[PSXBatou]

Interesting that they put a limit to it, I've only used it 2 or 3 times.

TBH as a consumer I am getting a bit sick of a car manufacturer telling me what I can and can't do to a car that I own. Infiniti didn't give me hassle on mods, BMW never gave me any second looks, but Audi is willing to bite the hand that feeds them and screw over their enthusiast crowd. While I love my S4 this will be at the back of my mind when it comes time to replace it. I've heard Porsche is more lenient..

[SwankPeRFection]

So, can it be reset?

On a separate note and from the posted work order picture in the limit link above.



Look at the wording for the TD1 detection. It has been discussed that the TD1 detection is done "automatically" by the scan tool when they plug in the cars at the dealership. But the wording on the work order makes you believe that the tech actually has to initiate the TD1 scan before it will detect it. Who here works for Audi and can spill the beans? Is it automatic or are you guys just bullshitting us all about it?

[s4buckeye]

Not sure why anyone finds it so hard to believe there is a 200 launch limit. It may be ridiculous, but VAG is not in business to replace high $$$ trannies, clutches and engines that have been bombed while under warranty. 200 LC starts is once per day for almost 7 months. The fact that you can doesn't mean that it is a good idea, or at least that must be how VAG views it. It was ran it up the flagpole to the Mothership with the TAC review - just looking perhaps to TD1 it based upon the hard driving/200 LC, knowing that such a car is likely modded?

As was said earlier, the best 0-60 times are mashed and not LC anyway.
