OK guys Im having a problem finding this little plug. This plug is the one that sits at the bottom of the coolant tank and gets the reading of the coolant level sensor if Im not mistaken. Can anybody tell me where can I find this plug complete. I went over to the dealer and this is what they gave me, only the bare shell of the plug not the complete assembly with connectors and cable. I got this for $15 they said they didnt not just sell the plug with complete assembly, if I wanted it I would have to get a new wiring harness, which I think its ridiculous. This is for a 2003 A4. Any help would be appreciated!
