On my way home from work yesterday my Check Engine light came on. 38,000km, 2 year old Cruze Diesel. I checked my ScanGauge and the code said P0272. A brief Google search led me to a few answers, one being Cylinder 4 Balance Fault. I cleared the code with the Gauge and will see if it comes back today on the way to and from work. My friend suggested it was possibly a random misfire that caused it and it may or may not come back on.
