Good day All,

I own a 2013 VW polo 1.6 TDI.

My question is what should the resistance reading be for these injectors?

I scanned my vehicle and getting the fault code: P0204 - Powertrain/ injector circuit-cylinder 4.

Wanting to check if the injector itself is the issue.

Hi there, I have the below info for you, I tested mine a while back and it tested around 200kOhm. Check the video link also https://youtu.be/DFLc7hEKnUk
VAG Error Code: 16588/9840/000516
EOBD II Error Code: P0204

Fault Location:
Injector 4 (N33) - Circuit Malfunction/Open Circuit

Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Lack/Loss of Power.
The engine may be harder to start.
Engine hesitation.

Wiring/Connector(s).
Injector 4 (N33).
Engine Control Module (ECM).

Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Read Measuring Value Blocks (MVB).
Low side signal current < 2.1 A.

When is the code detected?:
The P0204 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injector 4.

Description:
Engine Control Module (ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The Engine Control Module (ECM) will trigger the P0204 code when the resistance or voltage drop at the injector 4 is out of specifications.
