S3 Down on Power?

[ollyhawkeye]

The car just feels a bit sluggish (well compared to when I bought it) I am due a service in about 1000 miles (40000 mile one so plug change etc) and I must admit that my s3 feels a little down on power compared to other cars. I got tailed by a standard TT Quattro (a mate) almost neck and neck on a slip road this morning, this was the last straw and hence the post.

Has anyone else experienced this before a service? is it normal?

FYI I generally run on Tesco 99 fuel and its not been a problem before....

Any suggestions would be greatly received before I take it in to the stealer.

Hi Olly,

I know this feeling. Are you remapped or stock ? I felt mine was running rough and it went for its service (20k) when I got it back it was flying - felt so different. Then after a week or two it seemed to have lost its spark. I decided they must have reset something on the service. I did a battery disconnect for 20 mins and that seemed to improve things for a while. I never got to the bottom of it. I asked Audi to check and they said its running fine. Its as if the ECU is learning to back off the power I think.

PS - have you checked with VagCom for any errors that may be causing it to ****** ?

I am afraid I don't have the pleasures of VAG-COM yet (its on the list) so can't give you any further information on that one.

Its stock, no mods whatsoever, I think its intermittent too, sometimes it feels really eager and then the next its like its being held back.

Its not severe but noticeable, at first I just thought it was just me getting used to it but now after the TT I think there must be something wrong.

wow im so glad i found this thread !!!!!
mine is remapped and has been great but i got it back form audi yesturday with a new clutch etc and it felt great but i raced a mapped vxr with 4 ppl in the car last night and im distraught as i was hard pushed to get away form him and the car jusr seems sluggish compared to the normal WOOHOO pull :-( il try disconnecting the battery for 20 and let you guys know how i get on, im pretty upset today :'-(

S3-Dan, let me know how you get on, think I will try disconnecting the battery tomorrow morning and then go for some testing!! I do hope that does the trick, coupled with the service I reckon I might be in for a "new" S3...

hey ollie it worked
thank god for that !!! pulling like a train mind when i first fired up it says 'esp fault check manual' just go for a drive if it happens then up the road restart and put it off and on that worked for me its ok now im so happy lol..........time to find that smug f$**ng vauxhall n show him what a real audi goes like lmao

right that's it I'm off outside to brave the elements and un-plug the battery!! Thanks for the quick reply and hopefully this will do the trick!

Have a great weekend guys

 

[S3-Dan]

no probs dude
let me know how it goes hope it works im sure it will

I've done this a few times and find the car so much better for a while then it seems to revert back. I had another thread on here somewhere where I was asking the same things as I'm sure my car is cutting back for some reason. On my last 8L S3 it was the same and I know that had all sorts of MAF, coilpack issues - i've not seen or heard any of those type issues with the 8P. I run on Tesco 99 all the time.

Well I have just been out for a test drive after the battery disconnect and it really has made a massive difference. I'll inform the dealer to give me a print out of the errors in case there is a recurring problem. Last thing I want to be doing is disconnecting the battery every month, I wasn't buying into that when I handed my hard earned pennies.....

For now though it's put a massive smile back on my face!

urn right mate i dont wanna be doin this every month but its ok for now and another 12months warranty so il keep my peepers open for it happenin again
