At idle my CD5's oil dummy light is coming on. It doesn't happen anywhere above idle.

What could cause this? Me, my dad, and a couple others narrowed it down to three possible things:

Bad sending unit (130k on clock)
Oil pumping losing pressure during idle
Clogged filter

Any more thoughts or info would be appreciated

 

before you do anything,, chk the oil pressure , that will tell you if it is a mechanical or electrical issue ..

oil pan dented in ?? if so,, pick up tube partially blocked ?

 

I don't have a pressure reader. The 3 shops around my house conveniently don't have one today either.

No damage to oil pan AFAIK. I'm changing the oil and filter now though
