Engine light just came on

[mattCSLnut]

Driving at about 40 mph on a digi speed camera ridden A428, the engine shaped yellow light (not the EML light) just came on out of the blue . In the handbook it says "Exhaust emission values have deteriorated. Please arrange for the problem to be examined by BMW Service." Could this be yet another Lambda Probe ? The car already had one of these under warranty @ 39 000 in 2006. Is this a common fault ?

It will be because you have 100 cell cats on your car. Common occurence - no problems.

So what do I need do next then ?

Right ... so I should just get use to this light coming on from time to time. I'll check it again in the morning and see if it clears itself overnight. I presume the ECU will keep this fault in it's memory. Is it worth having a diagnostic plugged in to clear any stored faults ?

Mine has only come on once in the 15 months i've had 100 cell cats on.

The light came on and i shit myself but in the morning the light had gone off.

Like Rob says no biggy

Get the fault code read, it may be fook all, but it may have nothing to do with your lamda and be something more sinister. Also be careful which dealer you go to as they may charge you due to the exhaust mod, my ex dealer prob would try

Is it running 100% right?

My normal m3 engine light came on with 100 cell cats but the csl has been ok up to now. Although I have only ever put v power in, but I doubt the tesco stuff will be the cause.

Yeah... the car seem just fine. Still goes like the clappers. Same soundtrack but I've noticed the driver side pair of tail pipes are considerably more foul/sooty then the passenger pair. I wonder if this is an indicator of anything to do with my engine light on ? which it still is.
