I have a 99 2.8 quattro with 98k miles on it and for some reason its been feelin weak lately. My check engine light is on again and i need to get it checked out, and i plan on changing my spark plugs soon. I also plan on getting a chip and intake, maybe thatll help it a little..[X(]

 

dont drive your car anymore, never good to drive with your CEL on. and a chip would hurt more than help while your problem persists. get your car towed to a certified audi mechanic if possible and once you get in shape, you can go all out w/ chip and intake

 

well, ive been driving it around a lot with the light on, so has my mom when she had it. See, the lights always been on, weve had it checked before and it just keeps coming back, usually theres no reason. I dont know what to do, it hink it might actually be something this time..............is it really that bad if you drive it with the light on?

 

There is a reason for a CEL. You just haven't found the cause.

Don't chip or modify your car unless you have repaired all that needs to be fixed, and have it in to condition.

 

its not gonna make things better with the chip and stuff, first figure out whats wrong get it fixed and keep running the engine for about a week if you find there are no problems and it pulls like before then its alll right to goahead with the chip and stuff, i dont think its with the spark plugs if the engine management light is coming on, but anyway get it all checked up!

 

ya my light is on too, how much $ is it to get it checked out usually? (just from the diagnosing plug in in the rear ash tray)

 

i think it's free at any autozone location

well i got it checked at autozone, it turns out that my o2 sensor is jacked, i need a new one. How many hours of labor should this take to fix?
I also got another code, but the guy didnt know what it meant, this is what it said though- "p0411-The PCM has determined that the flow detected in the secondary air injection system is incorrect for the current engine operating conditions"<<<anyone knows what this means or whats causing this? Could it be linked to the o2 sensor?

 

Wow ..
I have an 03 , and my CEL is always on .
I go to the dealer, they get it to go off , then a week later , its on agian.
Car drives fine though .

 

go to autozone
