Yes, sometimes an "idiot light" will malfunction and give a false indication. Of course it can also malfuncion the opposite way and give no indication when there is zero or low oil pressure.

I would not take the owners word for this. Have the coach checked by a qualified diesel mechanic. You can offer this at your expense, but if the pressure is indeed low, I'd pass on it. If it is a malfunctioning light, have the owner make the repair and reimburse you or drop the price to allow for this.

I have the same engine and same light problem. I had a CAT dealer check the pressure and it was OK. He reminded me if there is a serious oil pressure problem the engine is programmed to shut down befor damage is done anyway.
