My service engine soon light just came on and was wanting to know if there are any service codes that would specify the cause?

 

try to make sure ur gas cap is fully closed that happened to me???? lol

 

How many miles are on your car?

 

just kidding..

 

Generally speaking, yes, a code should pop up on the scan tool. If you don't have one, a lot of places will check it for free. Pep Boys comes to mind, at least around here.

 

any aftermarket intake system installed? any test pipes? all those could be factors?

 

i had mine go on too this week....i went to the dealership and they said mine was a malfunction of the afr...

 

I've had the MIL come on and it was a random code not related to anything that I'd done to the car. Once I reset it, it never came back.

Best thing to do is get someone to check your code.

 

I don't own a Z, but (before buying my own scan tool) I had my BMW checked at Autozone for the generic OBDII readout.

They will ask you two things 1. How long has it been on for? (just reply, over a week) and 2. When's the last time you filled up? (just reply, over a week)

If you say anything else they'll tell you to come back or check the gas cap.

 

I had never heard of the gas cap issue prior to my engine light coming on... unfortunately isn't the gas cap... bummer. I checked the MAFS to see if it was gunked with filter oil from the NISMO CAI, but clean as a whistle. I didn't realize those stores would check the OBD code for free... I think I'm going to do that. I have about 57,000 on it. The only other time this light came on was when I stalled the car (at around 14,000) and my dome lights went out and the service engine soon light came on. I took it to the dealer and they replaced the ECU and some other computer component for free. I had punched it on the freeway (going about 80) and the car stuttered as if the TCS was on (but it wasn't)... I am wondering if that had anything to do with it. At any rate... I think I'm going to go get it checked.
