Took our 2013 Cayenne to the dealer yesterday for an oil usage issue. We started a short trip two bars down then lost another 2 bars driving 200 miles putting us at the minimum oil level. Understand that each oil level light segment equals 250cc - As we lost two additional in 200 miles, that means we lost 500cc or 16oz - one pint in 200 miles. A quart of oil every 400 miles seems to be more than what should be expected.

Previously they checked and found the reason for our Check Engine' light was a faulty diesel particulate filter sensor.
DPF sensor part came in -and- getting another dash clock as the second hand fell off.
