P0202 means the engine control unit detected an electrical fault (open circuit, short, or out-of-range resistance) in the wiring or driver for the cylinder 2 fuel injector. The injector itself may be fine while the wiring, connector, or ECU driver is at fault. Left unrepaired it causes a cylinder 2 misfire. Typical repair runs about 60 to 350 EUR depending on whether it is wiring or a replacement injector.

P0202 on a Volkswagen means the engine control unit detected an electrical fault (open circuit, short, or out-of-range resistance) in the wiring or driver for the cylinder 2 fuel injector. The injector itself may be fine while the wiring, connector, or ECU driver is at fault. Left unrepaired it causes a cylinder 2 misfire.

What does P0202 mean on a Volkswagen?
Volkswagen Golf
2004-2024On TSI petrol Golfs the injector connectors sit close to the cylinder head and the locking clips become brittle with heat, causing intermittent cylinder 2 faults. On TDI diesel models the common-rail injectors are far more expensive and replacement usually means the workshop must read and write the injector quantity-correction (IMA/coding) values with a VAG tool, which generic OBD2 cannot do.

How to diagnose P0202 on a Volkswagen with OBD2
Follow these steps to pinpoint the root cause of P0202:
- Read the stored code and freeze frame with Skanyx to confirm it is P0202 and note the conditions (RPM, load, coolant temp) when it set
- Check for companion misfire codes (P0300 or P0302) which point to a genuine combustion problem on cylinder 2
- Inspect the cylinder 2 injector connector and harness for corrosion, looseness, melted pins, or chafing
- With the engine off, measure the injector winding resistance with a multimeter and compare against the workshop spec (most petrol injectors read roughly 12-17 ohms)
- Check for the injector control and supply circuits with a multimeter or test light, and swap the suspect injector to another cylinder to see if the fault follows it
- Note that per-injector coding, flow balance, and quantity-correction values are not on generic OBD2 - read those with a brand tool such as Carly, OBDeleven, or XENTRY, or have a workshop verify them

FAQ: P0202 on Volkswagen
Does P0202 mean the injector is bad?
Not necessarily. P0202 is an electrical circuit fault for cylinder 2, and the wiring, connector, or ECU driver is at fault just as often as the injector itself. Check the connector and harness before buying a new injector.
Can I drive with a P0202 code?
For a short distance, yes, but you should not. A dead cylinder 2 injector causes a misfire that pushes unburnt fuel into the exhaust and can overheat and ruin the catalytic converter. Fix it promptly to avoid a far bigger bill.
How do I know if it is the wiring or the injector?
Measure the injector resistance and compare it to spec, then inspect and wiggle-test the connector and harness. If resistance is in spec and the wiring is clean, suspect the circuit or ECU driver. Swapping the injector to another cylinder shows whether the fault moves with the part.
Will a bad injector cause a misfire code too?
Often yes. A cylinder 2 injector that stops delivering fuel triggers a misfire, so you may also see P0300 (random) or P0302 (cylinder 2) stored alongside P0202.
Is it cheaper to clean an injector than replace it?
Cleaning helps a clogged or dirty injector, but P0202 is an electrical fault, not a flow problem, so cleaning rarely fixes it. The fix is repairing the circuit or replacing a failed injector.
