Question Engine light on - no iDrive/any other messages

My engine light just came on.
Zero messages on the dash or iDrive.

Just a lonely engine lamp ON.

Of course it could be a million things
without reading the code. Car still drive fine though.

Maybe just the O2 sensor/spacer not working and its picking
up my Akrapovic decat section?

Hello,

Did you find out what the issue was? I have been googling but all my results so far related to other issues, such as torque reduction etc.

I have the same issue. The engine lamp is constantly active, but no fault codes or any other messages. It just appeared when starting up the car today.

Regards.

Turns out its the catalytic sensor.
I'm running evolve decat pipes.
So the sensors are thinking that the cats. have failed and the emission is too high.

I cleared the codes and its all fine.
