hello to all and a happy new year,I joined a golf 3 year 1993 1.9 d with oil light is blinking I changed the two switches indicator light engine oil to the cylinder head of the color blue and the gray one on the oil filter, but the light will continue to blink then I thought I would check the oil pressure and the control by the switch blue on the cylinder head, the cold pressure and 5 bar then heating up to 1 bar,speeding up the pressure rises ,what do you think?
