Rear Badge Doesn't Flip Up

[Clinton]

So my rear camera has been intermittently not working for a while.
I've noticed it's when the weather is cold. The camera itself seems fine but the badge doesn't flip up and when I go check the badge is also locked. After driving it or after putting it in and out of reverse a few times it'll fix.



No codes when scanning it.

Yep had that problem on my mk6 , the cold , WD 40 , even the house locks are sticky , its damn cold .
I have noticed my push button start gets sticky in winter , needs a few jabs .

Putting common WD 40 on anything like that only makes it worse as it leaves a residue which attracts dust and crap. The correct stuff is Silicone spray which doesnt leave a residue and is a lubricant , not a penetrative like WD 40

Where abouts should I be using it on?
I'm not really sure if it's like jammed where it needs lubrication however as when I try open it with my hand it's locked. Like I can pull the badge up but it's not unlocked. When I put it in reverse I don't think the mechanism is moving at all as I don't hear it attempt to make the whirring noise of the badge flipping.

It will have a point that it swivels on otherwise check the electrical connections if no noise of it working

@clinton: Hi.

Certainly pursue the "sticky lock" suggestion - but as previously advised, don't use WD40.

IMO, WD40 is horrible stuff - it should be banned, or at the very least every can should contain a warning sticker about its use (not many know, but "WD" stands for "Water Displacement" - it should never be used as a cleaning agent - again IMO)

But I digress - anyhow, I'm not sure which version RVC is on your car. However, because your picture is missing the "bendy lines", I'm guessing that it's the low-line camera. Based on this guess, here's how your RVC is wired:


On my picture:

• R189 =RVC
• J794 = MIB (the unit inside the glove box)
• J519 = the module @ address hex09 on the CAN network which VCDS calls "BCM" and OBDeleven calls "central electrics module"
• The 2 x connections between R189 and J794 are a coaxial video cable that holds the vision signal from the camera
• T4bt = the 4 x pin connector on the RVC (separate to the connector on the RVC for the coax video-cable)

So, if your "sticky lock" investigation doesn't help - maybe do these steps:

1. first look at the fuse. The "C" fuse-block is behind the glove-box door -like this:
   
2. Then grab a multi-meter and check that battery volts appear at pin#1 on the actual RVC connector. Note: this power supply is what's known as a "Terminal 15" (T15) voltage which means that the ignition must be switched-ON
3. Then check the integrity of the earth connection on the RVC (i.e. pin #2 )
4. Finally, check volts on pin #4 (at the RVC connector). This is the actual "Gate-open" signal (in truth, the gate-open signal is the rising edge of the voltage waveform)- the "Gate-close" signal comes via another source.
   The blue/black wire in my diagram is also the wire that provides power to the right-side reversing-light.
   For this check (again, with ignition-ON):
   
   • First confirm that the "resting" volts on pin #4 =0V
   • Hand-brake ON and
   • Put the car into reverse gear
   • With this configuration, you should have FULL battery volts on pin #4, and the right-side reverse-light should illuminate (actually, both reverse lights should turn-ON)

So just flip the badge up and then spray silicon on the sides of the badge where it flips? Is there a point of where it unlocks that should be checked?
