Dreaded Engine Light.. Advice needed

[Mull3t]

Hi

I have a 2005 R53 MCS, over the last week the engine light has been coming up in yellow for small periods of time (the engine outline logo). It will randomly appear and then disappear after a while or when the car restarts and then may not come back for hours or days.

Not sure if this is linked but when it did come on once for some reason I decided to rev it to around 4/5rpm and then switched the ignition off and started again and then it disapeared again.

I am going to get this booked into the garage just to be on the safe side but my question is;

Does this sound normal to come on so random and then disappear so often? If so what could this be? A few people I have spoken to about mention if it was something serious it would stay on all the time regardless.

Thanks

Not normal! Do you have a scan tool to read codes?

Nopes

Going to book it in hopefully for this week, the specialist garage do a free error check, just seems a bit strange it comes and gos at random...

Possibly a faulty lambda/oxygen sensor.

Okay so dropped it off today and they ran a quick test, results come back that something to do with the air compressor... They mention that this was either the pipes/clips to the super charger or the supercharger itself! Tbh I haven't had any issues with the car lagging when driving only really a rough idle which goes after the car warms up. Anyone had an similar experience to this? I'm hoping it isn't the supercharger itself... They mentioned needed to do more tests tomorrow to be sure.

Just as an update; call from the garage this morning fault is a air boost sensor and a broken pipe.

Thanks for help
