I don’t think these are the tests that fault it in pre check as they take too long to complete and the car faults just after flipping the actuators open fast during the pre check ( you can hear then actuate if you just press the ignition but leave your foot off the brake ). After resetting the code, and restarting, the fault stayed gone, but this time I shut it back off and ran the test again in INPA.Īt the bottom left of the pic it shows the volts in low red zone.still at a good 12.4 volt without the engine running, but the “Integral TV Rampe2” and “Integral TV schliessen” both took too long to complete ( these start climbing several seconds after the test flips the butterflies open and closed quickly so this must be something to do with a several second slow test of the butterflies ). The fault showed that it occurred at 10.5 volts so I was pretty sure it was a low voltage condition that caused it.maybe, but seems there is something else going on with my actuators.įinally today, it faulted again after a long drive when I restarted the car to head out again so I grabbed my laptop real quick and plugged it in to test the actuators. I hooked up INPA and checked it, but all was well on the test so I reset it and went on.

Well, seems that my throttle actuator gear replacement a few 1000 miles ago did good as far as the gears go, but the other day bank 1 faulted for the first time when I didn’t put the car on the trickle charger for a couple of days.
