  Q: Could low engine oil pressure be a sign that the Oil Pressure Switch needs attention on Volkswagen Rabbit?

  A:

  A low engine oil pressure may indicate that the engine requires rebuilding since one of the low oil pressure indicators, the so-called idiot light, advances only at a critical condition of the oil pressure. Although a factory oil pressure gauge would be more informative than a warning light, it also only gives relative information. A more accurate determination is one that is made by means of a mechanical oil pressure gauge. In order to conduct this test, grab the oil pressure sending unit on the side of the oil filter housing and unscrew it then snap the hose to the oil pressure gauge with Teflon tape or thread sealant as necessary. Also, hook on an accurate tachometer to the engine according to what the manufacturer says. Lastly, adjust the oil pressure when the engine is already at the usual operating temperature and at the designated engine speed; a very low pressure can be an indication that the bearings and / or the Oil Pump is worn out.
