Well the dealer could have done the radical, unheard of, bold and unusual action of screwing a mechanical oil pressure gauge into the engine to see what the actual oil pressure was, or reading it through a scanner by plugging in the device.
You could have low oil pressure due to a plugged oil pump screen, loose oil pump pickup tube, or a faulty oil pump.
By all means have SOMEBODY determine actual oil pressure. You don't want to be driving on low oil pressure.

Hello again
The dealer called me today and stated that they have checked the oil pressure and pump etc, and there are no issues there. They beleive it to be something electrical which is causing the gauge to fall and the low oil pressure light to come on.
Does anyone have any thoughts about this.
Help:(

Had the same fright with my 03 ESV. The problem is a faulty gage cluster. GM sent out a "silent recall" on it about a year ago. Dealer should be able to confirm. GM extended warranty to 70K miles.

Just a quick update and still looking ofr answers, the oil pressure sending unit, swihch, and pump have been replaced and the problem is still occurring.
The mechanic is very adament about it not being the the gauge cluster.
Vajon was your oil gauge causing you the exact same problems and if so how long was it before the gauge cluster was found to be the culprit?

it's straight forward. I haven't replaced mine yet but did change the ones on my buddy's Chevy 1/2 ton truck which are the same. Remember 70% of your stopping power is coming from the front...get good pads. Make sure your rotors ar also withing tolerances and not grooved.

I am about to pull out my hair:::: the dealer called today and stated that they have not found the cause at this point and have been advised to tear down the engine.
I don't know how to feel at this point. The dealer keeps ensuring me that they will find the problem and then laughed and said look at things on the other side....if the motor has a problem and they can not find it once it is taken apart, then cadillac will be sending a new motor and at least i will be the only driver on that motor.
I am so frustrated:(

So they are saying they checked the oil pressure with an analog gauge and it's good and they want to tear down the engine anyway?
Makes no sense.
Let's be rational here: either it's actual low oil pressure in the engine or it's an electrical/gauge issue. One or the other. Either the reading is "true" or it is false.
If true, tear down engine
If false, tear apart gauge system

Yes Sir, thats what they said alright, they started tearing it down yesterday. It appears that after they checked all of these things the problem was still occurring and they could not find the root, so they are tearing down the motor. When they put the new motor in( and i am sure they will since I really don't beleive they will find anything) and the oil light comes on, maybe then some one will listen and go back to the gauge as the cause. I suggested it 3 times and was told, "oh i pretty certain that is not " I really wish you could call them and talk some sense into somebody!

Absolutely amazing. Well, at least you get a new engine. The dealer gets a lot of $ and GM gets screwed. And afterward, you'll get a new gage cluster too.
