Horn and MFSW buttons not working
Wondering if there is anybody out there that can understand this weird problem on my 2007 Audi S3...
My horn and buttons on the steering wheel do not work at all, nor do they light up. It seems there is no power to them.
I had it in at Audi today for a service and mentioned it to them, they took it apart and made sure everything was connected properly which it was. Now they want 2 hours labour just to investigate the problem!
On VCDS I remember them saying something like no operating power to the steering control unit.
I replaced the MFSW with a FBMFSW about 2 months ago. Everything was plug and play and worked fine. Around 2 weeks ago, my horn stopped working but everything else still functioned. Now, everything has completely packed up.
