Tech calls up, the (get the f*ck out of my way) horn not working. Tech had already replaced the clock spring and steering wheel electronics. Copy coding from old module and applied to the new module. Was about to replace the J519 Central Electronics. Had tech do the Output Test on the J519, horns work.
Steering wheel electronics doesn't see horn request. Run the VIN, I show it should have part number 1K0-953-549-AK for Steering Wheel electronics, it has 1K0-953-549-BK. Tech double checks with dealer, 1K0-953-549-AK was in fact superseded to 1K0-953-549-BK.
I ask what was the part number of the original steering wheel electronics... "1K0-953-549-BK". No, the original one, not the replacement. "1K0-953-549-BK".
So the long and short of it, some one had already replaced the steering wheel electronics and had the soft coding messed up. This guy puts in what would be the 3rd steering wheel electronics, but copies over bad soft coding. Once I sorted out the soft coding, the horn worked.
Oddly, when he put the original clock spring back in, the horn didn't work. We suspect another shop replaced the steering wheel electronics, didn't code it or anything and then the car ended up in this guy's bay with no knowledge of previous work.
