So my wife told me the other day that the engine light had popped up so I told her to go get it checked. Two out of the three shops say that it has something to do with my fuel cap or a line is leaking. But she is now going to this shop to get our a/c fixed and he is telling her that one of my coils is messing up. He reset the ecu and told her to bring it back when the light pops back up so he can find out which one it is. I told her when she goes back up there to find out what are all the codes it flashing so I can look them up myself. I just wanted to ask if any one has ran into this problem on 04 S4. Also the first two places was good friend of our that work at a shop and just read the codes for us but don't really know how to work on Audis

 

Go to Advanced Auto and they will read the code for free. Have them write the code(s) and look them up. Go from there. I had an 03' A4 Turbo and the coils are notorious for going out, Easy fix but costly (@ $50+ a piece) and it's good to change plugs while you're at it.

 

yeah thanks bro she said that what the mech said at this shop she is going to. but that is a really good ideal to go ahead and change them all out. i hope that fixes it cuz i'm really looking forward to driving it! oooo and for everyone on here that help me out with the rims size deal thank i'll throw some pics up as soon as i can!

 

ooo just to put it out there i will be putting up the old ones for sale just make me a offer. like i said give me a few day to get the pics up.

 

I don't think anyone in their right mind would buy used VW/Audi coils.

 

I think he was talking about his old wheel.

 

lol yeah i meant my old rims. But it's cool I should have been a little clearer on that! If you go to the post saying hello that I put up a while back you can see them. I just checked and it is still on the front page. They are TSW so like I said before make an offer and we can go from there. But again thanks for the insight on the coil issue we have our mech checking out that right now.

 

BTW if the coils or a coil goes out the car will buck like crazy under acceleration. Just my .02

 

yeah and she says thats not happening. she says it drives smooth so i really don't know whats going on and it sucks cuz i'm not home right now so she is trying to get everything handle for me before i come home.

 

Yeah the coil would instantly throw a CEL if it were misfiring, Maybe bad plugs or a fuel filter clog. It doesnt seem like anything too serious
