P0205 on Audi
Injector Circuit/Open - Cylinder 5
P0205 on Audi vehicles indicates injector circuit/open - cylinder 5. Au7o has documented this code across 1 Audi model — most commonly on R8. P0205 is a fuel-system code meaning the engine computer detected an electrical problem (an open circuit or out-of-range condition) in the fuel injector circuit for cylinder number 5. The PCM controls each injector with a precise electrical pulse, and it monitors that circuit for proper current flow. When the cylinder 5 injector circuit doesn't respond as expected — typically an open or a wiring fault — this code sets. It generally causes a misfire on that cylinder, rough idle, hesitation, reduced power, and possibly hard starting, since cylinder 5 isn't being fueled correctly. Typical repair costs on Audi range from $1,500 to $4,000, depending on the specific model and root cause.
Common Causes of P0205
- •Failed or open fuel injector on cylinder 5
- •Open or shorted wiring in the injector control circuit
- •Corroded, loose, or damaged injector connector
- •Poor power feed or driver fault from the PCM/injector circuit
- •Chafed or broken injector harness
- •Blown fuse feeding the injector bank (where applicable)
- •PCM injector driver failure (less common)

- Direct-Injection Fuel Injector Failure2008-2023
The FSI direct-injection injectors shared across the VAG family (Audi/VW/Porsche) are a documented R8 failure point. Injectors can stick open or closed; a stuck-open injector dumps raw fuel into the cylinder and can wash down the bore, while a stuck-closed injector starves the cylinder. One well-known r8talk case had 6 of 8 injectors fail on a 2008 V8 at only 14,000 miles. Symptoms overlap with coil failure (misfires), so proper diagnosis is important, and carbon buildup on the injector tips is a contributing factor.

What does P0205 mean on Audi?▼
P0205 stands for "Injector Circuit/Open - Cylinder 5." P0205 is a fuel-system code meaning the engine computer detected an electrical problem (an open circuit or out-of-range condition) in the fuel injector circuit for cylinder number 5. The PCM controls each injector with a precise electrical pulse, and it monitors that circuit for proper current flow. When the cylinder 5 injector circuit doesn't respond as expected — typically an open or a wiring fault — this code sets. It generally causes a misfire on that cylinder, rough idle, hesitation, reduced power, and possibly hard starting, since cylinder 5 isn't being fueled correctly. On Audi specifically, this code is documented across 1 model.
What causes P0205 on Audi vehicles?▼
Common causes on Audi: Failed or open fuel injector on cylinder 5, Open or shorted wiring in the injector control circuit, Corroded, loose, or damaged injector connector, Poor power feed or driver fault from the PCM/injector circuit, Chafed or broken injector harness. Specific causes vary by model and year — see the per-model sections below.
