Thinking of adding an APR or another kind of ECU chip to an '07 2.0T. Does Audi work with any companies in which chips will not void the engine warranty? I know APR has encryption which will not show itself in normal diagnostic service testing. More concerned with retail sale value than hurting the engine...

listen dude by experience, if they wanna void your warrenty, they will. the computer can tell..dont listen to apr or any other chip out there..my b7 has 6000 miles on it and at the first oil change i had the apr chip with the stock feature(lets me "disable" the chip to be undetected)..the tech ran the computer(standard procedure) and told me that he can tell that the chip was installed..he told me that regulary people pay it no mind..they mostly look at if you exceded 130mph,overreved the car, or any malfuntion that the ecu wants to throw down..and to answer part two, no matter what your warranty will be voided even if audi does it or not..its the same chip that does the same features the rest of them do..

Just a question...but can't you delete some stuff from the memory with the APR chip?

correct! what the chip is designed to do is to delete(or surpass) the limiters,restrictors,and governers that the saftey computer has. by doing so it kind of tunes your car into duping maximum fuel for the amount of pedal your giving.(hence the whiplash you get the first time you drive the car with the engaged chip.)even thought it is nothing but a software, dealers can tell as easy as if you remove a sticker on a laptop,ipod,ect that contains a (warranty vioded if removed sticker)..

This is kind of depressing to hear.

My question is this: Only enthusiasts will be dinking around with these chips right? I'd assume these same people are using forums like these. Why havent we heard more reports of people getting hosed by their dealers? While dealers may be able to see the "signs" that an ECU was installed is there any way they can actually confirm this?

Any APR officials want to step in and clarify this?

my buddy that works at audi showed me the error code that popped up on the screen when i took it to him for my first oil change at 5k miles..its like a nnumerical error code with some other characters. i had the apr chip installed on mine. its there and will show up. im not an apr official but i was on top of clarifyong this rumor, but i wont stop here, you pass 135 and your warranty is done, you pass 6k rmps and your **** is done..dont beleive, then knock yourself out, my friend was amazed when he saw 167mph on that computer.

Yeah when ever a customer comes in and i perform a service i have to run faults depending on the service, but i can definately can tell if the car has been chipped.. I really don;t care since i am into performance tuning and what not. But all those chip makers are lying when they say their software is undetectable! Trust me, its all up to the tech that is working on your car whether or not he wants to be a d*ck and let his service manager know and void ur warranty

Its really very simple to check if the ecu has stock software installed or if its been modified. Just because you "disable" the chiped software does not mean that chiped software is not still present in the ecu. Its as simple as checking bit by bit to ensure only the stock data (program) is in the ecu when they do a diagnostic, as soon as they detect any data is changed thy know someone has chipped or tampered with the ecu somehow.

And while anybody doing actual ECU programming could block or fake the tattltale codes, their attorneys would tell the that would be a very, very, dangerous idea from a product liability perspective.

Uhmm why would they void the warranty if you exceed
6000 RPM ? My 2.0T Tiptronic, will run all
the way to 6800 RPM (the indicated redline)
if you stand it on all the way. This is a stock
car.

My dealership knew my tt was chiped. they didnt really care, but nothing really went wrong with it either. Just chipping these cars isnt stressing anything so its not like your gonna have lots of problems for the dealer to give you a hard time over in the first place. But if something does randomly go wrong and they want to be dicks well they will be able to and audis are not cheap to get fixed. Once I installed a stage 3 kit and a bunch of other stuff though it was a differnt story. they didnt even like touching it anymore and nothing was covered. Even with that though I didnt have a single engine problem just some nuked tranys. I doubt I will ever void the warrenty on an expensive car again. If I really feel I need to get the car chipped I think I will buy a spare ECU and have it chipped so I can have the original stock one to put back in if anything does go wrong.

On a dealer level there is NOTHING we can do to figure out the car is chipped with what we have on hand for diagnostic equipment if the car is in stock mode.

Even in performance mode they could feel obviously that it was chipped but if they were to datalog the car, not even that easy with the dealer tools compared to vag-com, the results they would get are generally on most models still whithin acceptable specs from Audi as they usually only list the min and max for some of the sensors.. that being said.. Audi doesn't supply ANY information anymore either digitially or on paper for the new models. To get that sort of information even what blocksto check to read boost is done automatically if you have a code related to it.. So if you had an overboost code.. unlikely... it would pick that up and then lead you through the diagnostic procedure but not even always tell you what to look for just does it fit in these specs.. which a chipped car still may do.


The only real way for Audi to check and see if its chpped is during a diagnostic sessin where the car is connected back to their technical help offices in michigan. Bascally like that windows support thing where they can connect to your computer and control it.. Audi can do the same thing with the dealer scan tool. With this conection they do have the ability to read off the code that is on the ECM. Since they can do that in theory they could do a check and compare files to a stock one.. but if you think they have the software at their desk to do that you are fooling yourself.

So the truth of the matter is on a dealer end there is no definitive way for ANY person at the dealership to determine if you are chipped. Other then some little features here and there vag com is more capable then the dealer scan tools. Especialy since the new software on the scan tools is 100% idiot proof and won't let you do anything on your own.

no sh*t?? i went in for 5k service and the guy came out and told me he had done a software "update". I have (had) apr software installed, and i'd hit somewhere round 160. Took it on highway 135 mph limit was in place, so he had reprogrammed my chip back to stock. it doesn't pull as hard now. Knowing that they can pull up speeds, i'm going to get it reflashed by APR tech and keep it under 135 for warranty. damn good to know that my warranty is still intact. thank god the techs at my audi dealer weren't having a bad day.

Plus on the TT s-tronic in sport mode the rpms go into red a little anyway stock.

When I was at the dealer the other day; the service tech told me they can in fact detect if the car has been chip tuned. He said they really don't say anything if told before hand that it is chipped.
