I bought my car last week, having read all those topics about L, M and N flashes? How do I know if I had those upgrades? sorry if my question is kinda dumb?

any insights out there?

 

Trix8,

Turn the key to the ON position without actually attempting to start the car.

Then pump the brakes rougly 20-23 times within the first 8 seconds of turning on the car.

If the OIL gauge needle "sweeps" to Low back to Middle then you have at least the "L" map.
