Relay clicking sound

[gurvir44]

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.
