Horn failure

[sapphireblack]

Discovered today only one horn is working, sounds like it should be coming from a BMW Isetta more than an X6. Surprised no note on Mondays MOT but maybe its failed since?

Noticed also what looks like water stains on the silver door trims inside, anyone else have this? Seems it will polish off but I'm mindful when i booked the MOT dealership said they would sterilize all surfaces touched by technicians. It looks like somethings been sprayed on and left to dry?

If any horn was working it would pass doesn't need both to be working for mot

Probably some form of wet wipe used. We’ve got them all over the office as we have to clean all desks, keyboards, phones and seats at the start and end of each working day. The Clinell ones leave what look like water marks on everything. Should just wipe off again with a slightly damp cloth.

Horn wise, you need a new ‘low pitch’ unit…. https://www.realoem.com/bmw/enUS/part?i ... 1337288096

Sometimes hitting it (gently) with a rubber mallet can make them work again. It could just be wet or a bad plug. Whichever side it’s on, it’s behind the fog light grille. I think there’s one behind each side (low on one, high on the other).

I have tried a water based wet wipe and a mild polish with no change so far. Duraglit later i think.

I’d be asking them what they used and how to get it off - or to sort it as they did it!

I had to resort to gentle polishing with Duraglit, nothing liquid based did anything. Annoyed and I'll tell them for sure on Monday.

Investigated the feeble horn and the low tone is dead. It worked once after a tap but not again. £47 ish plus VAT apparently, serious scuffed wrists getting at them but i will at least save a half hour (or more) labour charge. I'll order one on Monday.
