need help with a diagnosis
The seatbelt light is a bit puzzling, but I vote for my favourite
culprit: the infamous "Oil Pressure Warning System Control Unit".
It is a little "L" shaped printed circuit that sits inside the
instrument pod, behind the speedometer.
In my case, hairline cracks developed in the solder of the pins on the
circuit board. The oil light would come on, and eventually the warning
buzzer. I took the board out (assembly is the reverse of removal, says
the Bentley).
I did replace all the oil sensors one by one, until I banged on the
cluster in exasperation - and the light and buzzer stopped bothering me.
That is when I looked for a loose connection.
If you are not handy with a soldering iron, a few weeks ago, someone
mentioned they had the board for sale.
Good luck!

The last 2 times I have driven the rocc about 20 minutes into the drive the oil light and seatbelt(I think the other was seatbelt) light will come on. When this first happened I thought, shit I'm low on oil 'cause the engine burns about ? quart every 100 miles or so.

So I fired up the engine again and poured in some more fluid as the engine was running. It took about 8oz and I could tell the water was moving 'cause it was squirting out the hole at the tope of the radiator.
