Mk7 Oil Pressure Rapid Throttle Modulation

Oil Pressure – Continued

After recording some initial oil pressure data to verify the data logging system was functioning correctly I drove the GTI under different conditions to evaluate how the oil pressure varied with the conditions.

Cold engine start up and first couple of minutes of driving:

Rapidly cycling the accelerator pedal:

Remaining in third gear and accelerating at lower RPM to build boost pressure:

Accelerating downshifting, DSG transmission:

Slowing going into a turn and then accelerating:

Stopping and then quickly accelerating:

Reference:

  • LOW PRESSURE STAGE
  • Oil pressure at idle: 0.85 to 1.6 bar (12.3 to 23.2 psi)
  • Oil pressure at 2,000 RPM: 1.2 to 1.6 bar (17.4 to 23.2 psi)
  • Oil pressure at 3,700 RPM: 1.2 to 1.6 bar (17.4 to 23.2 psi)

  • HIGH PRESSURE STAGE
  • Oil pressure at idle: 0.85 to 4.0 bar (12.3 to 43 psi)
  • Oil pressure at 2,000 RPM: 2.0 to 2.4 bar (29 to 34.8 psi)
  • Oil pressure at 3,700 RPM: 3 to 4 bar (43 to 58 psi)

  1. Hi Jeff, Wondering if you csn provide any insights on when the car will reach normal operating oil pressure from a cold start and normal driving. Does it reach normal operating pressure pretty quickly?

    1. From the four logs I have recorded the oil pressure drops to the lower range around 5-6 minutes after beginning to drive. All of the logs I’ve recorded so far have been after the car was sitting for a few hours. I don’t know how soon after starting the engine the oil pressure would decrease if the engine was hot, such as after refilling the gas tank.
