I agree. I've had this a few times with my E, my 320 and my 500. Sometimes is the ABS/ESP/BAS, sometimes not the ESP and sometimes not the ABS. In some cases it'll lock the tranny shifter. In any case the solution was either a faulty brake switch, steering sensor, the ABS cntrl unit, and, believe it or not, at one time they had to replace the trip computer - this was the one that involved the tranny lock on my 50 500.Drew said:Stop by your dealer if you can, and show it to them. They may be able to squeeze you in. I think that it's likely a switch problem. Mine came on once and then went off after starting (and didn't show up again). They ended up replacing the a switch and no lights since.
