Relay clicking sound
Just finished installing a Hfs-3v.3 in my Audi A4 1.8T. When I start the car the water level light stays on even though there's enough water, decided to pull the float sensor and it got rid of the light. Now when I start it, light comes on for a few seconds, turns off and the rest of the gauge lights up. Once it hit the gas the guard lights turn off and I hear a rapid clicking sound like a relay. It does that till the RPMs go back to idle. Any suggestions?
I'll adjust the float and see if that takes car of the water light. |

Re: Relay clicking sound
Two things:
1. Check the arm of the level sensor is pointing up at 45 degrees with a full tank. 2. What wiring diagram did you use for the installation?

Red wire to the + of the fuel injector (Black with green stripe) Used all factory grounds so they should be good too. Will check the arm today. |

Re: Relay clicking sound
This is a 20V 1.8T, you may like to swap the red and green wire of of the ECU harness to the fuel injector (+) & (-) pins. See diagram below:

Re: Relay clicking sound
I used the continuity mode on a multi-meter to trace the wires back from the ECU to the fuel injector. You just want me to swap + to - and - to +?

I couldn't make this any clearer with text and diagram.

Re: Relay clicking sound
Thanks richard, i fixed everything with the solution you provided. I need a bit of help fine tuning now. Often times ill accelerate and the Low level water light will come on, along with the water injection light indicating fail safe mode. How do i fine tune it to avoid that? Do i use the SC on the display? Or the 3 turn dials inside the unit.
