Yesterday when I started my 545, a picture of the engine and the words increased emissions appeared on the heads up display. After a while the signals go out and service engine soon light is on dash. I am looking for recommendations on what should I do. Thanks in advance.

I just had this also. If it's your first time let the gas run out and fill up from a known good station. Chances are it could be gas. If it stays on have the code run. My Y pipe, according to the dealer, was letting air out. The Y pipe runs right through the engine, though. Anywho... I had the car at the dealer for that and another problem with heat. The problem with my heat was the thermostat which they replaced under warranty. I called to schedule the Y pipe at a different shop and had about a week wait to get in there. Just before I was scheduled to go my light turned off and hasn't come back on. I suspect it was the thermostat as well and since others had the same problem with the thermostat fixing it I'm hoping that's all it was.
