    Hi everyone.
    Hope this thread will be usefull to someone with the same problem I had today...
    Right, to short the story, I have done the stupidity (take note, this was an accident!),
    of turning the steering wheel more over than the slip ring could take...
    As some of you will know, the consequences were a broken ring, so my airbag light came on straight away, and all the steering wheer buttons stop working... I confess my first reaction was... , and I walked out of the car moaning to my self about how stupid I was...
    Well, a few momments later, and after calm down, I thougt, well, moaning is not going to solve the problem, so I decide to stop fell sorry for my self and get my hand on the work...

    FIRST THINGS FIRST!
    DISCONNECT YOU NEGATIVE CABLE FROM THE BATTERY, AND ALLOW 5 MINUTES.
    THIS IS NOT ROCKET SCIENCE, BUT DO IT AT YOUR OWN RISK.
    YOU WILL NEED TO CLEAR THE ERRORS ON THE ECU, IN ORDER TO THE AIBAG LIGHT TO GO OFF.

    First, romove the steering wheel, using a torx T30, insert it through the small orifice, push it and keep it pressed until the airbag is released, without stop pressing, and with your other hand, pull the airbag of.

    I have then removed the slip ring cover, you do not need to do this, I have done it just to confirm the broken ribbon cable...
    IMAG0443.jpg

    Here you can see the broken ribbon cable... so my suspicion was confirmed!
    IMAG0444.jpg

    The removal of the slip ring is straight forward, by removing 3 black torx bolts... easy!

    Remove the robbon from the slip ring, that will make it easier to work on it...

    The broken end needs to be straightned...

    IMAG0447.jpg

    Scrape the white plastic covering the copper lanes, in order to be able to solder.
    Remove the grey plastic that is holding the ribbon, make 3 cuts in the middle of the lanes an insert the ribbon in place to be solded.

    Apply some solder pste, to obtain a good and clean contact.

    And procced with soldering...
    IMAG0451.jpg

    Insert the ribbon back into the slip ring, attention to the loops and to the inbetween plastic ribbon.
    IMAG0452.jpg

    Put everything back, clear the AIRBAG ecu, and job done... What a relief, when I saw the airbag light going off...

    I really hope this can help someone out there...
    Have a nice day!

    F**king AWESOME!!!!!!!!!!!!!!!!
    I've a sticking horn for ages now (not literally as Ive taken the fuse out!)
    Local garage couldnt figure it out when I went for MOT (although at that time it was sticking intermittently) but luckily on that day it wasnt sticking so fortunately passed the MOT!
    But now its constant so I'm driving around with the fuse out.
    I concluded it may be the slip ring and couldnt find a e60 slip ring removal/change guide or post anywhere!
    The closest I got was a youtube video of someone removing the steering wheel! and a few posts regarding other vehicles
    I found a place who have used sliprings in stock but thought theres no point in me ordering one if I dont even know what to do!!
    Now I'll give it a go when ive got a few days free, it might not even be the slip ring or ribbon but thanks a million!

    loooooooool
    Glad that my post is helping...
    For a sticking horn, and after I had the above job done, I would say is not the slip ring... reason is, even the horn signal is can based, therefore if was the slip ring the chances were something else would stop working, like your steering buttons... but you can always check the slip ring for short or open circuit, simply using an multimeter...p
    As soon as you have the airbag out, you will see 3 plugs on the back of it, the 2 in the middle is for the airbag itself, and then you have one more on the side for the horn.
    That one, plugs into a sort of brown ribbon cable type, that goes around the airbag, which contains 4 (if I am not wrong...) pressure sensitive points, or whatever you want to call it, lol, these act as switches.
    So I would say you have one of these in constant contact, or sticky.
    Hope you get success resolving you sticking horn....

    Thanks for that bud.
    Somebody on this forum had a similar problem and mentioned something about "brown ribbon" and I may have mistaken that for the slip ring ribbon.
    I sort figured it might not have been that after you mentioned none of the steering wheel buttons worked but on mine everything else works except for the horn.
    Thanks for your help. Now I know exactly what to do..... when I do eventually get round to doing it!
