hello. I recently got in the car and when I started it up, the oil pressure light came on and the warning chimes started dinging. I was only about 2 miles from the house, so I limped it home not applying any unnecessary throttle to spool the turbo. However, the noises i heard were very similar to an Evil Kneivel windup motorcycle from my youth. I assumed it was the turbo starving for oil. I had it towed to a local shop and even though I never triggered a "check engine" light, the computer stated a few oil related codes. The tech tested all and everything was good so gauged the pressure and it read next to nothing. I have no weird sounds from the motor. What to do? Please help.
