Weird issues with horn on 2011 Panamera 4
Thank you for all the advice you’ve given each time I’ve asked on here!
I wanted to see which pin is + so I turned the IG ON and had my son press the horn while I measured the voltage output from the connector. There is a square side and a rounded side so you can only connect one way. The square side pin is the + side. I got 12 V on both high pitch horn and low pitch horn connectors so the horns must have failed somehow.
The local dealer pricing was $26x.xx. This includes the two new revised horns and two new connectors to splice in. I did not get them because I was concerned that it may not be the horns that failed until I verified so. If I find the printout the parts guy kindly gave I’ll post the part numbers. (I have a problem with misplacing things).
Rat3d M, is it possible you got the + and - side crossed when you connected the new horns?
Definitely test them before replacing the bumper/apron. (Apron is what the technical instructions call it).

The updated part #s as promised:
970-635-021-02 and 970-635-022-02 for the horns
970-612-935-00 for an adapter, need 2.
I found the old part number on eEuroparts.com and am interested in ordering there. I am not fond of splicing because I am not very good at it. It's also the cheapest source compared to FCP Euro and Advance Auto (CarQuest where we live).

Hi. I'm pretty sure the poles are reversed in the new horns. When I applied 12 V + to the rounded side and - to the square side of the horn it tooted. Now to try the horns on the car....
The wires are good as far as I can tell. Kind of silly but the replacement horns require 12 V the other way, but the wiring is opposite for the old horns. Just gotta swap + to - and - to +...
When videoing I was trying to avoid showing that the car needs a wash! Well, on the bright side, I’m glad you didn’t say I need to replace those condensers, (the things that look like radiators/with the fins if I named them correctly). They look pretty banged up from road debris, but that’s beyond my capabilities. I have a shop vac I bought in the last few months from Costco. I originally got it to suck out fuel from the engine valley when I pulled the fuel rail, but I found paper towels worked effectively to sop up the fuel. My son (14 yrs old) eventually used it to clean his room. I wonder if he’d let me use it for a dirty job like this....
So, no need to buy those two adapters! (I got them on the way home Thursday morning, before I figured out how to pull the pins). It’s a much cleaner repair/install with no possible source of failure from splicing the wiring in! Wonder what the return policy is as they had them in stock?....
