I have a 94 540ia that is seems to be stuck in winter mode. Mine has the M (manual) and * snowflake switch next to the shifter. Every time I start it it starts out in winter mode. I swithc it to M but if I shift into 4 to get (Sport) it still displays a snow flake next to the gear and no S. I cannot get the E to come up at all. I disconnected the battery overnight. No help. Any suggestions
