The "Check Gages" light comes on all the time now.

The "check gages" light comes on in response to the oil pressure (not oil level) gage dropping too low. Step one is to check to make sure the engine has oil pressure. Use a mechanical gage inserted directly into the engine when the oil pressure sensor screws in. If the pressure is good, you need to check the gage. Your dealer has a tool that attaches to the connector from the pressure switch that gose to the gage. He can then test the gage, cluster and circuit wiring. If that is ok the culprit is the oil pressure sensor itself. I normally don't recommend replacing parts without a proper diagnosis but an oil pressure switch is relatively inexpensive. You might want to try that first. It's relatively common anf if that's the culprit, you will save a bunch of $$$ no having to go to your dealer. If you still have a problem, you have at least eliminated one item and are only out a couple of bucks.
