I was just wondering if the engine light was one of the lovely side-effects of a flash tune?

I noticed mine was on today and can't say I have ever seen it before. I did a quick read-up and all it mentions is that the car is now operating outside of emissions standards. Has this light been on the whole 6 months I've had my car (and I'm a blind *beep*) or is it an indicator that I should get it checked out?

Nah, I'm talking about a flash tune on a mildly modded car.

EDIT* Injectors, Debung, CAI.

Check your cat grudgee, it could have collapsed causing the emissions light to come on, you'll notice if it gets worse as the performance may start to suffer higher in the rev range

faulty o2 sensor also causes the engine light to come on.... I had a blown o2 sensor fuse... which was caused by me fitting the heat shield and in the process shorting the oo2 sensor wire which caused the 02 sensor fuse to blow... took me a a while to figure this out

Hey Grudgee

Engine light is a problem that sometimes occures after flash tune. If you have a custom tune take it back to your tuner so they can get rid of the light ,if a generic tune then you may have to put up with it.

To check if it is in the tune ,flash it back to standard, start the engine and see if the light goes away if it is still there take it to a dealer to check that something is not wrong with your cat.

Good luck

PS may not start in standard mode with your bigger injectors so go back to the second tune and try :buttrock:

Wouldn't be a BF by any chance? Mine started doing that after my exhaust was fitted, has to do with the second O2 sensor reading emissions that are out of normal operating range. I just clear the fault code using my gauges, comes back after a big spurt.
