Welcome.
Please click user cp and edit details to add your vehicle and location to your profile, that can prove useful when seeking assistance.

If this was close on the heels of your maintenance, it's possible you knocked something loose or didn't get the airbox quite properly situated. So it's worthwhile to retrace your steps and recheck everything.

The only way to know exactly the reason for the MIL is to plug in a scanner and let it talk to the car.

Good luck.

Im quite sure its the air filter thats not installed the side cover was off when i went into look but having tampered around with this it still has yellow warning light.

Is there a engine diagnostics code reader that i can purchace for this car i noticed you can get them cheaply for 04 plates onward :( I have an 03 plate.
