This is my first post on the forum so please excuse if it is rookie-ish. My 2005 roadster is giving me fits. The local dealer did 2 oil changes, and shortly after each (one was over-filled and drained) the oil warning indicator (idiot light) would come on intermittently. It always had oil in it, but would light up for no reason. I just took it to an independant garage that I trust, and gave them Mobil 1 0w40 ECF to use to be sure I was getting what is spec'ed, also thinking this might cure my indicator issue. It did not. Now in fact the service LCD warning is flashing -2400, and the odometer has gone missing entirely. They tried everything they knew, but it is messed up. No other symptoms or issues, and it has a 3 month old battery. ANY suggestions or similar problems would be appreciated since I am baffled and as much as I love that car, I have low tolerance for things like this. Is there a way to reset the entire service warning system? Thanks in advance for any and all input.
