The problem could be associated with many different components, and as you suspected the intercooler hoses are likely suspect. You have checked them already but it won't hurt to just re-check them, looking for any oily signs on the intercooler hoses. A small split can sometimes be difficult to find, but any area which has been breeched will normally have signs of oil around it.
The MAF sensor is another common failure point, you do not mention if your BMW is petrol or diesel, but if it is diesel then often by disconnecting the MAF sensor you may be able to restore power for a short period. This will bring on the management light but may give a clue to the problem.
The codes do need to be read from the system to give an accurate idea of what the problem is.
