I Have a BMW E46 328i just recently it has thrown up the eml light and the yellow triangle symbol and goes into limp mode only does this when starting engine from cold and letting it idle for a while after about 30 seconds eml light comes on with the yellow triangle symbol and stays on until engine has warmed up to normal running temperature switch engine off then restart engine starts and runs ok eml light goes out,Also i have no communication between diagnostic socket and the DME unit either the one inside the vehicle or the one under the bonnet so unable to read any fault codes.
SOURCE: Eml and diagnostic problems
As for the limp mode unless you have an expensive diagnostic system this usually has to be done by BMW (anything to get ya to a dealership!!). The comms problem, is the key turned in the ignition?
