P0201 on Volkswagen: Causes, Symptoms and Fix Cost
Quick Answer
Moderate SeveritySafe to drive (short-term)Volkswagen
P0201 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 1 fuel injector. The injector itself may be fine while the wiring, connector, or ECU driver is at fault. Left unrepaired it causes a cylinder 1 misfire. Typical repair runs about 60 to 350 EUR depending on whether it is wiring or a replacement injector.

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 1 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 P0201 on a Volkswagen with OBD2
Follow these steps to pinpoint the root cause of P0201:
- Read the stored code and freeze frame with Skanyx to confirm it is P0201 and note the conditions (RPM, load, coolant temp) when it set
- Check for companion misfire codes (P0300 or P0301) which point to a genuine combustion problem on cylinder 1
- Inspect the cylinder 1 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
