P0202 on SEAT
Injector Circuit/Open - Cylinder 2
P0202 on SEAT vehicles indicates injector circuit/open - cylinder 2. Au7o has documented this code across 2 SEAT models — most commonly on Ibiza, Leon. This code means the Engine Control Module detected an electrical problem (open circuit or out-of-range resistance) in the fuel injector control circuit for cylinder 2. The ECM switches each injector on and off through this circuit, and it monitors the circuit to confirm the injector is responding. P0202 indicates the computer isn't getting the expected electrical feedback for that specific injector, so cylinder 2 may not be fueling correctly. This commonly causes a misfire, rough running, and reduced power on that cylinder. Typical repair costs on SEAT range from $300 to $4,000, depending on the specific model and root cause.
Common Causes of P0202
- •Damaged or corroded injector connector at cylinder 2
- •Open or shorted wiring in the injector control circuit
- •Failed (electrically open) fuel injector on cylinder 2
- •Loose or backed-out connector pin
- •Poor ground or power feed to the injector
- •Faulty injector driver inside the ECM/PCM
- •Chafed harness causing intermittent open
P0202 on SEAT by Model
SEAT Ibiza(1 issue)
- Ibiza / Leon 1.6 TDI Common-Rail Injector Failure2009-2020
The 1.6 TDI common-rail engine in Ibiza Mk4/5, Leon Mk2/3 (and across VW Group small diesels) suffers Bosch injector failure typically at 100,000-180,000 km. Symptoms: rough cold start, individual-cylinder misfire, sometimes back-leak overwhelming the rail pressure regulator. Injector copper washers often re-seal poorly after the first removal.
SEAT Leon(1 issue)
- Leon Mk2 2.0 TDI PD (BKD) Injector Failure2005-2010
The BKD 2.0 TDI Pump-Düse engine in Leon Mk2 (and Golf Mk5, Passat B6, Audi A3 8P) suffers PD injector failure, particularly on long-life servicing. Failure modes: misfire on one cylinder, hard starting, white smoke, sooty exhaust. Often accompanied by cracked cylinder head between #2 and #3 due to local overheating.
