I'm not advising anyone to do this, there are other threads that discus the repercussions. Secondly, it may not be reversible, liquid tape may tough, or even impossible to remove. But that noise makes me think that my car is broken, and it drives me nuts. Acquire a few parts, a 5 watt 8 to 10 ohm resistor, some liquid tape, and some black wire ties. Take a resistor and bend one of the wires as shown Don't trim the wire yet, it come in as a handy handle. Stick the longer wire into something to hold the piece, and coat it with liquid tape. Make several coatings. I did 4. Now trim the longer wire to the same length as the over wire. Clean the ends of the wire. So, open the hood and remove the black plastic cover that covers the front part of the radiator. The noise make is on the driver's side of the car a has the bit of blue plastic. Unplug the noise maker. Push at the center of the bottom edge of the connector from the front and pull down. See the metal tabs in the connector, you will be plugging in the resistor in the connector. There are two ways it can go in, It needs to go in above the tabs. You should fell some resistance (pun not intended) as you push it in, if you do not try it the other way. At this point in time you need to test the connection. Turn on the car and look on the upper display for an error, and a message telling you to visit the dealer. If you got the message, don't proceed. Fix the connection first. Now you need to water proof the connection. Fill in the connector housing with the resistor with liquid tape , to make a water tight seal. You may need to flip it back and forth to make sure it is completely filled. Use multiple coats. After it has dried, you will need to tie it down so that a) it doesn't get knocked out, b) you don't want it to bounce around and make noise! I use black wire ties, so that it would blend in. I tied the wires of the car and the connector, but NOT the resistor to an existing cable. Pop the cover back on, and pat yourself on the back for helping eliminating noise pollution.
