P0272 on SEAT
Cylinder 4 Contribution/Balance Fault
P0272 on SEAT vehicles indicates cylinder 4 contribution/balance fault. Au7o has documented this code across 1 SEAT model — most commonly on Leon. 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. Typical repair costs on SEAT range from $400 to $4,000, depending on the specific model and root cause.
Common Causes of P0272
- •Dirty, clogged, or faulty fuel injector on cylinder 4
- •Injector wiring or connector fault
- •Low or uneven cylinder compression
- •Vacuum leak affecting cylinder 4
- •Fuel delivery or pressure issues
- •Carbon buildup on intake valve (direct injection)
- •Mechanical issue (worn rings, valve, or head gasket)
