It's 100% relay sound, this is not the argument!
The argument is why it happens and what is it?

its not the fuel pump relay. its the after run coolant pump relay. it seems to get triggered when the radiator out temp and the engine coolant temp get within about 1-3C of each other. best way to get it clicking is to do stop and go driving with the a/c off on a warm day. my car does this too, and thats all i have been able to figure out. the clicking is occurring because the relay shuts off above 1000 rpm. if you have vcds you can hook up and watch whats going on. replacing the relay like some of the threads i have found does nothing.
best i can tell the ecu thinks the car needs to turn the afterrun pump on to circulate coolant thru the turbo, what i cant find is the parameters that set this behavior.
i also believe if you let the car idle for around ten minutes the timer on the circuit expires and it will stop clicking.
