Hi all,
I suspected the low horn on my E86 wasn't working, and I was just working on my R53 (which is parked next to my E86), and suddenly saw the horns, and thought 'i wonder if they fit?', and... They do!
A Mini R50/R53 horn is a direct replacement for an E85/E86 horn. You need to change the bracket over, but that's just the bolt you'd undo to remove the horn anyway, so no big deal there. The wiring connector is exactly the same, and there is enough slack in the wiring to match the mini horn's different orientation.
I post this, as I think I've seen people struggling to find horns for the Z4 for a reasonable price. Hopefully I've not made this up!
Here are the mini parts numbers
https://www.realoem.com/bmw/enUS/showparts?id=RE32-EUR-03-2006-R53-Mini-Cooper_S&diagId=61_1418
Under £10 on eBay, and plenty to choose from if you search for 'r53 horn' (rather than the part number)
I think the r56, and possibly E90 series horns are also compatible, but do your own checks there. R50/R53 definitely is
