P0201 on Volkswagen
Injector Circuit/Open - Cylinder 1
P0201 on Volkswagen vehicles indicates injector circuit/open - cylinder 1. Au7o has documented this code across 1 Volkswagen model — most commonly on Caddy. P0201 means the engine computer detected an electrical problem in the wiring or control circuit for the fuel injector on cylinder 1. The PCM pulses each injector open and back ground, and when it sees an open circuit, a short, or abnormal resistance on cylinder 1's injector circuit, it sets this code. In practice it means cylinder 1 may not be getting fuel injected properly, which can cause a misfire, rough running, or a no-start on that cylinder. It points to the injector itself or its wiring, not to a fuel-pressure problem affecting the whole engine. Typical repair costs on Volkswagen range from $1,600 to $3,800, depending on the specific model and root cause.
Common Causes of P0201
- •Damaged or corroded injector connector or terminals at cylinder 1
- •Broken, chafed, or shorted injector wiring harness
- •Failed (open or shorted) fuel injector on cylinder 1
- •Loose or poor ground/power feed to the injector circuit
- •Blown injector fuse or relay feeding the bank
- •Failed injector driver inside the PCM/ECM
P0201 on Volkswagen by Model
Volkswagen Caddy(1 issue)
- TDI fuel injector failure (expensive when replaced as a set)2010-2015
The TDI common-rail injectors on the Caddy are a recognised weak point and can fail with little or no warning. When one fails, owners report sputtering, rough running and limp mode. VW workshops generally insist on replacing all injectors together, so the OEM repair runs into the thousands. Frequent short journeys and poor-quality (supermarket) diesel are cited contributors.

What does P0201 mean on Volkswagen?▼
P0201 stands for "Injector Circuit/Open - Cylinder 1." P0201 means the engine computer detected an electrical problem in the wiring or control circuit for the fuel injector on cylinder 1.
