P0272 is an OBD-II diagnostic trouble code meaning “Cylinder 4 Contribution/Balance Fault.” This code means the engine computer detected that cylinder 4 is contributing less power than the rest of the cylinders. By measuring crankshaft acceleration during each power stroke, the computer estimates each cylinder's output and flags any that fall short. When cylinder 4 is below the balance threshold, this code sets, typically indicating a fuel injector or fueling fault on that cylinder. Symptoms include rough idle, misfire-like behavior, and reduced power. This code is most commonly reported on 2005-2010 SEAT Leon (Reference, Style, FR), with repair costs ranging from $400 to $4,000.
