The control buttons of my steering wheel are not working, help!!!

[mariocaz]

Hi guys,

I need help please, the controls (volume and songs control) are not working at all in my steering wheel in my Z4 E85 2007.

I removed my steering wheel becuase I sent it for a carbon fiber job and when I removed it I cut a little cable by mistake with the screwdriver that I used to removed it and I see is one of the controls, I fixed the cable but still not working at all the controls.

What else I can check ?, do this have a fuse that I could check ?, I dont know what else to do, I am desperate and very sad because my stupidity.

Please help me!

Blown fuse for sure. Hard to know which one exactly so it's a case of measuring the volts across each one in turn with the ignition on. You should have less than 0.1V across all good fuses.

Is there a fuse for the MFSW? I would thought this is just a serial interface to the switches. Might well be wrong.

Have you double checked your wiring? Is the cable properly plugged into the slip ring, or into the back of the actual switches?

Hope you get it fixed.

It will be fused as it’s necessary to prevent fire risk from shorting. It will likely be in with some other ancillary.

Have you checked this with the engine running or at a stop with ignition off. If you are parked with the Radio on ..Ignition off....the Steering controls do not function . ....this is normal ...

Check Fuse F28....

I checked the fuses but all fine there, so checked every corner of my steering wheel and saw that I did a mess and cut some cables of the 2 paddles, so that was the mean problem, because the cable that I fixed I did it wrong, one side of that cable were for each of the paddles, so now I did all well and my steering wheel is working again, yeaaahhh!!!!

Thank you so much, for your nice help as always!!!
