The Exhaust Emission Light can come on if the car is driven slowly over short distances.It will not happen on cars driven at speed. A short trip of ten miles at over 3000 revs should reset the warning light,although it may not go out for a couple of days after you have tried it . Hope this helps and saves a bill at the local dealer. JK

It sounds like it could be a problem with the catalytic converter. If it is this, as well as the continued loss of power you may also notice that the exhaust emissions start to occasionally haves quite a strong and horrible smell.
If your local mechanic has an OBD lead he/she will still be able to plug it into the car and read the fault code from the cars ECU (computer thingy!). You don't need to wait for the light to come on again as the fault code should still be in the memory of CPU.
If your local garage does not have the correct OBD software for your car, you can still go to the stealership, ahem I mean BMW dealership (hehe..!) as reading the fault code is quick and very cheap to do. At least you will know if it the catalytic converter at fault, (I hope it is not as this one can be expensive to replace, sorry). Good Luck Angela.
