You're right about the valve. You get them on a lot of new motorbikes its called a set valve or something like that and it's there to do exactly what you said...

I think it is sorted now!

Its weird about the exhaust though, it is SO much quieter now (appart from very low rpm which is still nice and throaty), and with the solenoid attached to the valve and the engine on tick over the valve is fully open. I think by pushing the lever fully up as suggested in the "exhaust mod" thread it actually keeps it permanently half open which is the cause of the roar/rocket sound that it used to produce, now, I think the valve closes at high rpm but I don't know for sure as I need someone to look at the valve while I rev the engine. I'm going to play with it this weekend, but I'm pretty sure there is less high end grunt now than there was with the exhaust mod (up to the flat spot that is!).
 
Just read this by suggestion from another member!

I am in the same exact situation!!

My car has only got 3000 kms, but since the first thrashings, I noticed a "flat" spot around 6300 rpm. I changed to NGK plugs just to see if there was any change, but nothing. THIS WAS NOT CONSISTENT! Some days I would not even notice the miss, and some days if was noticeable even without looking at the rev counter.

Yesterday I got a remap from APR. All went pretty much OK until I was coming back home and I noticed a sharp flat spot while giving it some in 3rd gear, and the check engine light went on. Today, I scaned the ecu and I threw THE EXACT SAME CODES AS YOU! Random misfires and cilinder 3 misfires, and, the most amazing thing is that the Revs are almost the same, and the speed too (130 km/h give or take, 3rd gear WOT pull). The light went off, car drives OK but havent stepped on it a lot. A small pull today made me feel that the spot was not there.....:huh:

It is obviously much more apparent at high gears, 1st and 2nd arent much noticeable.


Please let me know if you solve this, I havent mod the exhaust but unfortunately I doubt this is the case. My symptoms are 100% spot on same as yours..... :(

I am even more worried now since you have tried replacing plugs and coils (which I thought could be a problem).

Do you use always the same fuel? Is it a "reliable" pump?
Did you try any other change such as MAF sensor or O2 sensor?

Hope we can get it sorted!
 
For that to be similar rev and errors I am going to a ECU or software glitch.... maybe related with a faulty sensor...

Since I plugged the exhaust valve back into the solenoid it seems to be fine, I think I noticed a tiny bit of flatness today, although that could have been traction control or something, I'll check the VAG-COM when I get 5 minutes.

Didn't try the MAF or O2, I always use v-power without fail, from either of the two shell garages near my flat in Guildford.

Maybe you have a problem with your exhaust value? Or maybe there is something wrong with our cats.
 
I am leaning a bit more towards sensor....the car did the same while stock and now it seems it is much more noticeable after the remap.....
 
Last night I tried the OEM plugs I first removed from the carm but the misfire is still there. I will try today with some NGK but same heat range as stock. It seems to be a fueling issue. Has anyone got any info on similar problems? I know also user Madalex had something similar and he took a long time to solve it.

:(
 
There is some concern that the std fuel pump can't cope above 320bhp, so i don't know , maybe it's hit fuel cut on your car earlier?

p
 
I dont think so, that kind of problem throws a DTC for low fuel pressure usually.....my DTC is misfire on cylinder 3......:(
 
Just thinking has everyone had the software update from Audi that some S3's needed?

There may have been a problem from the start that Audi have not been fully truthful about.....

Good thinking Batman , i know when spin got his GIAC man at Stattler , they checked for faults AND uploaded the latest Audi softwhere!

Two other members have had there car mapped there with NO issues???????????????

p
 
Was thinking the same but didn't like to say. The main reason i was so impressed with statller was the time he dedicates to your car, the benefits of a smaller family run buisiness I guess, I may be wrong but I think he said it was Audi software version 005.

It may just be that the Guys with problems are just unlucky, annoying though.

THIS IS VERY INTERESTING!

Another car with the same remap is working well. Several users on this forum have a similar problem (some work and some dont).

Does anyone know how the remap actually works? I was told it increases the % on the stock values, so if there is an update, the remap would also be different. I dont know the truth to this though :(

Also, does anyone know if I can check the software version in my car using vag com???

so its breaking a reasonably high percentage of cars but not all of them.
i think we might be in a bit of denial here... what other result would you expect if something is going bust in the car from too much power?
 
I dont know, I just know I had the stock software put back and I feel much better.... the car pulls quite nice on the stock software and I have no codes or flaws now, dont know what else to say. I think I will keep it this way.


I was told today by a friend who maps cars that the misfire is in my case, very probably caused by the ecu pulling excess timing due to excessive detonation/knock. This sounds very logical, because the misfire isnt there if you are not WOT, if I pushed the car at 80% throttle the car would not misfire at all. This excessive ****** causes the misfire I could feel and hear.

Furthermore, this happens only on cilinder 3 because it is always the hottest, and most prone to knock (due to firing order)
 
Dont you have vag-com? You can try to log the knock sensor readings and timing ****** values.
 
I know it doesn't help, but it sounds to me that one of the cars that is misfiring needs to go on a rolling road with someone who has the ability to diagnose the fault and adjust the map to eliminate the issue.(which should be the map supplier at his expense)
Assuming the various agents are installing the map correctly (which I would expect) then the maps themselves need looking at unless the standard S3 is showing the same issue (mine doesn,t)
Revert back to the standard map,get a refund and wait until the fault has been identified and rectified before trying again
Unless someone wants to be the first with the big bang :notme:

I am now purchasing the Micro Can....but, on the other hand, I dont feel like being a guinea pig with my car, logging data FOR THEM! If there is one thing I wanted about this car, reason I bought it brand new, was having little issues! I thought the remap was far more proven and fault free.... I am fed up of logging data with my notebook (had an EVO VI on standalone, took me lots of efforts)

I know, but the APR dealer does not have a rolling road, nor the ability to modify the software, it is "install as it is", just burn it and that´s it!

Furthermore, there has been a big bang already down here.....one S3 melted a spark plug tip, which caused damage on the cilinder and one valve.....new engine is getting put.....:scared2:

Care to elaborate more on that? Which company was it tuned with? Any other mods? Conditions when it went kaboom?
 
It is a strange one, some people have issues others don't! is it the maps , the mapper, or the cars?

I'd like to think it's not the tunning companys fault as a whole , more the individual mapper/maps or the car?

p
 
Its difficult to say. to date we have examples of Revo'd/APR & GIAC cars - no examples of Bluefin to date also some of the cars are not being ran on the correct fuel so this must have an adverse affect. I'm still not woried as my car is running perfectly at the moment although if it did develop a fault i'd go with the advice given, flash back to standard and request a refund unless the Tuner was prepeared to fix/diagnose the fault at their own expense - we buy these things in good faith after all.

Another point to remember is that people are quick to complain when things go wrong but it would be interesting to know just how many cars are running fine on their remaps ?
 
Are all the cars that are experiencing problems totally and utterly standard in every other way apart from the map? ie standard exhaust/airfilter/spark plugs etc?

I would imagine you could get some ignition retardation at high RPM if you were running 95ron fuel instead of 98/99ron . What fuel is everyone using?
 
Anybody who buys a S3/Cupra/Ed30 should be putting 98-99RON fuel in the car! anyone who buys one of the above and put 95 RON in , then spends £600 on a remap to boost perforance is wasting there money and taking risks as the car manufacturer and the tuning company recomend 98RON minimum.

Theres a CC remaped Cupra on Cupra.net at the moment with ignition problems when trying to start the car, struggles to turn over and lights flash on the DIS , he took it to the dealers and they can't get into the ECU to sort it out!!!!!

p
 
My car was otherwise stock! I just changed plugs 3 times to see if that was the problem (misfire), sounded logical, but no luck. I was using our best fuel (labeled 100 octane). Only had the 98 RON APR file installed.

Now the car is flashed back to stock, I just returned from beating the **** out of it :jump: several runs in 3rd and 4th gear almost bouncing off at the rev limiter and the car is flawless, no lights no codes no nothing, just linear pull. I cant even feel the hesitation I felt before (maybe due to the fact that now my car has NGK plugs, same heat range as OEM plugs).
 
audi upgrades
you could try superchips, I think they're the only ones nobody on here has had any issues with (not that it means anything, we are a fairly small sample size) , apart from someone saying that the performance didnt seem too great.

I'm interested in going down the remap route in the future, and it would be a toss up between revo and superchips for me, but the few people with random misfires are making me think twice about it.

The chap I use to do all my non service work on all my cars is a revo dealer, he tells me they are fine, and would have no hesitation in getting it done. You could say that he would say that, but I've known him for years, and he's always been honest and straight up with me.
 
Thats it tho, there is something not right somewhere!!!! some cars are fine others not so. is it the car? is it the map? or is it the remapper?

p
 
cant be the remapper, they dont do anything to the map, they just load it up to the car.

In the cases where the car is misfiring before the remap is applied, then there is clearly a fault with the car.

In the cases where the car is running perfectly before the remap, but is misfiring after the remap, it must be the map that is causing the fault. Thats not to say that same map would cause problems on every s3, but more likely that that particular s3 is less tolerant of being mapped to that level than another s3. Every individual engine is different, some will make more power than others as standard, therefore I presume some will remap better than others.

I guess it sort of like CPU's, A 1ghz CPU is exactly the same as a 1.2ghz cpu, its just that during testing the one that is sold as 1.2ghz could be pushed to a higher clock speed and still maintain reliability, whereas the one at 1ghz could only maintain reliability at 1ghz. Also, some CPU's overclock (think of it like a remap, but for your cpu) better than others despite being sold as exactly the same spec.
 
I don't know???? thats why i'm in no rush to remap , it seems so hit and miss at the moment! and knowing that my good std S3 is making 280bhp and 280lbft on the rollers i can bide my time untill i feel fully happy that any issues with the maps have been ironed out!

I couldn't agree more. Infact, i'm using what you said because lately i'm seeing M6's & those long sleek looking 3dr Mercs pulling into Esso to get 95ron!!! :wtf::keule:

It's furiates me to see something like that... I mean, what on earth are they doing :uhm:
 
After reading some cases in this forum (as we all know, many forum members are from the UK alone), and considering there are LOTS of persons who do not read internet forums, I think there is some sort of issue in these cars, some glitch in the software which makes the remap work well in some of them and work poorly on others....I think the mapping companies will have to make a little more R&D.....

Lets not forget the S3 is not available in the USA, where most of the major tuning companies are based. Would be interesting to know how is the r&d performed. Do they send technicians here, or crate the engine over there?

Afaik, there are 2 mtm remapped S3s in singapore doing fine. One with a full turbo back exhaust, and another one remap only. Not that bad considering the heat they get there.
 
I am one happy chappy! :)

So I went to Regal today to give the coil packs that I borrowed back to Chris. I thought the flat spot was better, but alas on the motorway the flatspot came back in all its glory :(, so I was pretty ****** off and was gonna ask about trying the 310 map out to see if thats any better but Chris wasn't there today so I didn't.

On the way back home the I decided to put it back to stock with my flash loader, I then gunned over 7000rpm without a single issue, I was a bit miffed that it could be perfectly fine on stock but not on pump, so just for the hell of it I put it back to pump and gave it some stick.... nothing... no flatspot! Woohoo! So I then preceded to rape the crap out of the car the rest of the way home and it was totally faultless!! :arco:

So I guess it must have been the ECU calibrating itself to my dodgy exhaust mod so the problem remained even after I put the exhaust back to normal, and by reflashing the ECU it forced it to recalibrate itself to the standard exhaust.

Job done.

Congrats! Having any fun with the vag-com?

Lol, not even had time to use it once! been very busy burning it at both ends!

I'll do a sweep for error codes when I get back to make double sure its all good and I'll drop it back off at your gaff. PM me a day/time that you'll be in.

Cheers
 
Nice to know it looks like " you have sorted it out" :icon_thumright:
 
Theres a new casualty on Cupra.net , after having a APR remap he his having fuel cut issues at 4500 revs!!!!! only advice is uprated pump or take it back to APR and ask them to turn the boost down or flash it back to stock! Hit and miss!

To be fair the problems I've been having are nobodys fault but my own and if I just left the exhaust alone the car would have been fine all along.

p.s. Just got back from a hoon around surrey, the car didn't miss a beat, the extra power is awesome! loads of torque, really smooth delivery, very happy customer! :yahoo:
 
All good news then.

And the moral of the story is dont tamper with the exhaust flap!!
