Father Jack...love that username Dougal might be better though  Steve.

I have been known to use the odd or two, and like a wee beer now and then, so it is fairly appropriate !

Horn signals something left open. Door/boot/bonnet


Why does my neighbours f-ing 2015 Merc sound the horn every time its locked?
I'm sure its against regulators to do that these days

You were right it`s started doing it again  Steve.

10 minutes to replace

If it was the switch, wouldn`t it go off as soon as I locked it....and also, wouldn`t I have a bonnet open message on the display? Steve.

No, not always. They have a tendency to be working one minute, and then causing alarms at random times when locked. Very simple to change, you tube vids available if you do a search.

Ah right ok matey. I`ve just had a quick look after washing it...I assume the switch is behind the grill?

edit...found a video  Steve.

Yep, take the grille off, the switch is on the offside catch (drivers side) Whip the two torx screws out to loosen the catch assy, don’t lose the little plate. Unplug the lead to the switch which is under the catch, using a small screwdriver, prize out the knackered switch. Fit the new switch to the catch and refit the plug. Using the witness marks to help you align the catch assy, fit back on to the body not forgetting to fit the little plate.

Voila

Nice one, thanks. Just ordered one  Steve.

No problem, happy to help Steve. PS, did my front discs/pads this morning. Easy job and so far, touch wood, no squealing dragging brakes.

After having my rears done, I get a rotational squeak now and then, drives me mad  Steve.

Changed the switch just now. Probably would have been ok just to give it a good clean but, it`s swapped now. Fingers crossed that`s fixed it.
This is what the old one looked like...





 Steve.

Did changing the catch solve it?

I have a my2010 and was told that if it is the catch, it will beep when locking? Mine doesn’t beep when locking but randomly (and annoyingly) goes off fairly regularly.

Any ideas or should I just swap the switch and keep them crossed?

Hi mate. Yeah it seems to have worked. Takes about 10 mins to change,

Mine didn't beep on locking, only after the alarm went off and I silenced it. Steve.
