If its dinging that mean you have low or no oil pressure and you risk catastrophic damage to your engine if you drive it. Just because you have oil doesn't mean your oil pump is bad or filled with shrapnel. You need to have it looked at.I have searched the forum and been unable to find an answer to my exact problem....my oil light comes on and dings very loudly and constantly and I have full oil and am not due for an oil change yet...why does it keep doing this!? 1999 VW Bug-a-boo!
There is a chance that the patina could stay intact long enough to protect the engine for a little depending on how far he/she drove.I'd suggest you do the following steps:
1. check the electrical connector at the oil pressure sending unit, make sure it's tight and the metal not contaminated with oil or oxidized.
2. If the electrical connector appears to be good, have a mechanic hook up an oil pressure gauge to check the engine oil pressure.
If the pressure is good, replace the oil pressure sending unit.
If the pressure is low or zero, your engine is probably gone and you have to swap it with a new engine(considering you've driven your car with low oil pressure for some time, the engine is definitely damaged).
