The oxides that occur on zinc are often almost invisible to the naked eye so don't be surprised.įixing this horn is a really easy job and all you need is a flat-blade screwdriver (or a 3.5mm diameter rod or Allen Key), a needle file or emery board (cut to fit), sandpaper, small pliers and a portion of silicone grease. NOTE: several people have complained that they 'can't see any corrosion' but my method still fixed the problem. My years of experience in the electronics industry were with silicone grease and I haven't tried other types of grease so I can't guarantee them.) Please don't ask me if some other type of grease will work. (It's REALLY important to use silicone grease, otherwise this fix won't last, because the metal oxidises quite quickly. The clever Peugeot designer has put a brass or bronze tab in contact with a 'mazac' (zinc alloy) casting - a combination known to suffer from corrosion problems! My simple answer was to clean up the contact surfaces with a 'needle' file then apply a generous coating of silicone grease to keep out moisture and oxygen.

It turned out to be a very common Peugeot fault and it's easy to see why. Bashing the airbag would get it to work but, next day, it would be as bad as before. I bought this car in 2009 and it had the intermittent horn problem from the start, despite a 300 Euro 'service'.
