Parents came by for a visit over the weekend - the backup camera that was working with the previous POS Android head unit wasn't working with the slightly less POS Android head unit. The new head unit had come with a camera as part of the kit, but we figured we could just swap in the new one and everything would be good Alas....no.
The camera power supply line included with the new unit had a little white wire loop built in - head unit wouldn't see the signal. Snipped the wire - head unit sees the signal from the backup camera. So, we set to work pulling the old power supply wire and installed the new one. Did some futzing with the left rear bulb tray wiring (which also has a trailer wiring kit wired in).
Fast forward to the next day - pops sends a message that cruise control no longer works. Dammit, methinks. Must've pooched something with the wiring back there - messed up a brake light signal or something so the cruise decided to take a vacation....or something (wiring not my forté).
So, he brings the car back over - was about to dive into that rear bulb tray wiring again, but decided to plug in VCDS and check MB006 - and I see that the cruise switch on the turn signal stalk isn't even working - no change to the status in MB006 / 4.
So, figure it must be the turn signal stalk - I've had more than one of those die over the years. And luckily had a spare on in the parts bin.
Pull off the airbag, steering wheel, clockspring, and as I pull off that turn stalk, holding back the big wiring harness, the little 10-pin wiring harness that plugs in vertically....suddenly it's just hanging there. Usually that's a PITA to unseat due to the location and the tiny little release tab.
So....figure that's gotta be it and just bundle everything back quickly. Do a quick check with VCDS - yep, all the buttons change all the appropriate zeroes to ones.
