Check Engine light questions... (archive)

Hi - This weekend my 2000 M Roadsters check engine light came on. I've gone thru the archives and there is alot of good info about what it may potentially be (i.e. gas cap).

I did a little fiddling around and now I'm waiting to see if it goes away. If it doesn't I think I'll have to take it to the dealer to see what the code actually was - and if anything needs to be replaced.

My question is if I should put my car back to stock before I take it back to the dealer. Mostly I'm wondering about the Conforti software and the intake. I just don't want them to use that as the excuse (I've had both on the car for over 5K miles or so with absolutely no problems). Do you guys switch the software back when you take the car in to the dealer for a potential emissions type problem?

Thanks in advance,
Will
