cel light came on again
 

Check engine light came on again i have invidia N1 catbck exhaust do you think the dealership will give me any problems I live in Ca

Exhausts are pretty safe, but if anything put back on the stock exhaust then bring it in.

that is exactly what I did not want to hear but if I guess I should then I will but

this is the second time I'm going to have to bring in for cel 1st ecu prob now who knows whats wrong.

I seriously doubt the exhaust is the culprit but the dealership might give u problems if they see that its there.

cel light went off on its own this is really wierd, not sure what i should do now

Find out from a service manager if they can retrieve the code after the light has gone out, or whether the data is erased. If it is still available it is probably worth finding out what it was.

Do you have an aftermarket intake installed?

Just curious...
What ECU version do you have in your car? 810? 811? 812?

must know!

There is nothing a cat-back exhaust can do to possibly cause engine problems or void a warranty. If anyone ever tried to void your warranty over a cat-back, you could sue them. However...other parts that seem trivial (like an intake), CAN cause issues that could lead to engine malfunctions.

Guys no intake at all, I have a pair in Foley but I haven't installed it yet because I'm having trouble put it on my at
And I'm not sure what kind of ECU I got now is there anyway to checkt

The ECU is behind the glove box. You'll need to lie down on the passenger floor, contort your body and look behind the glove box. Look at the last 3 digits. You can also open the glove box, and get a glimpse that way. It's on the right side of the glove box (when opened).
