S1 . . . . When the fan kicks in there is an eratic clicking sound around the ECU area and car starts to run hesitantly. When temp comes down, fan goes off and car runs spot again Is there a relay or something around this area for the fans ? I think there may be a back feed problem to the fuel pump possibly as i think i can hear it priming on and off during the fan being on but not sure. any help greatfully appreciated
