Rear Reverse Camera Help Please

Hey so I know there is a lot on this topic regarding issues with the rear camera but I have not found a helpful guide for someone like me without a code reader to debug this issue.

2017 Golf TDI

The issue started when the flip rear camera either failed to deploy or deployed half way. Leading me to believe its a mechanical issue as opposed to an electrical issue. Now the rear flip handle/camera does not deploy at all and all I see are the guide line on the display.

I however checked:
SC18 fuse and that is ok.
Reveres lights OK.

What's the next step?

@MK7aholic: Hi.

Hmm........ If you expect that you will keep this car and you intend to deal with these problems as DIY - then I suggest that you consider throwing money at a god diagnostic device! It will definitely pay dividends and it will minimize repair angst!!

Given that you can't access the self-diagnostic information that's sitting in the car's fault memory (a serious limitation IMO) -I guess that you will need to remove the logo housing and investigate the latching mechanism.

I'm not sure that I agree with your dismissal that this problem may be caused by an electrical issue. It seems entirely possible (even perhaps, probable) from your words that this fault could result from an intermittent wiring/connector break- maybe?

In any event, if you are minded to accept my hypothesis above and if you own a multi-meter - this is the set-up for the rear lid latch:


Note: it's not shown on my diagram, but the wires on the latching mechanism also terminate on the Coupling point for rear lid before continuing to J519, which is located at the cabin front, under the dashboard.

Thanks Don @DV52 I appreciate the detailed schematic info! Question:
1. What is a decent diagnostic tool or one you recommend to use that can read deep into the memory?
2. Any idea what drive voltage is for the motor at Pin4?

Thanks again Mate!

1. What is a decent diagnostic tool or one you recommend to use that can read deep into the memory?
Hmm......... that simple question ain't easy to answer - notwithstanding that there are countless examples of folk that have answered this question on various forums.

The two most-common diagnostic devices are probably VCDS (made by Ross-Tech in your country) and OBDeleven, which is made in Erope. They are both very good tools IMO. I've used both for many years and each has it's own advantages and deficiencies.. My difficulty in answering your question is that I know nothing about how you value stuff - which is the essence of the decision making process when purchasing a diagnostic device (or any purchase, really).

VCDS and OBD11 have different pricing regimes and they have different usage limitations. For example, OBD11 has a significantly lower purchase price for the basic product - but an annual subscription is charged to do manual coding (coding changes can be made without a subscription using One Click Apps on the basic product)
On the other hand, VCDS has a much higher outright purchase cost for the basic model without restrictions on coding (and no subscription fee) - but it has a limit on the number of different VINs that can be applied to the device license. VCDS also has an unlimited VIN option - but it ain't cheap!!

There also limitations on compatibility with the range of cars in the VAG fleet. VCDS is NOT currently compatible with VAG models built after 2020 whereas OBD11 is currently suitable for VAG cars built before 2024. Also, OBD11 is compatible with lots of other non-VAG brands (VCDS is not).

Again, my problem in answering your question is that I don't know how you generally value each of these variances and in particular, how you might discount the individual deficiencies in dollar terms!!

2. Any idea what drive voltage is for the motor at Pin4?
I have an engineering background and I was taught by wizened lecturers at uni (long ago) that motor torque is dependent on the voltage applied to DC motors. So, I don't know from actual experience, but my hunch is that V53 will be powered via a 12V supply from the controlling module (I think)

Thanks for the write up!

Ok so finally able to look at this more closely. I have the access panel off. Fuse 18 is good. I now agree that it is probably an electrical issue as the latch doesn’t work which is electronic no sound in the latch or camera nothing. Connectors all look good. Not sure what to do next. I have a multimeter but I doubt anything is getting to the hatch. Or it’s at the hatch that there is a short or open…???

So I talked with the service department. They said most likely the camera as the hatch latch is controlled through the camera. Since bith are nit working makes sense. But they want $1800 just for the camera. I need to find another source as I am not paying that.

Any ideas? Was thinking of hunk yards etc.

Just buy the unit and replace it yourself. It's super easy although you will need triple square if i remember correctly

Yeah I know the physical installation isn’t hard. Paying $1900 for the assembly isn’t easy to swallow.

I am looking for alternatives. The part I need is 5GM-827-469-J-FOD

There has to be a way to figure out the dozens of camera assemblies that will work but have a different number. Given the number of failures of this assembly I am surprised there is no recall or TSB or reasonable replacement. $2000 for a FNG camera?

I want to find a used one but don’t know what numbers are compatible…..
Would appreciate any inputs on this.
Thanks

Damn. Why is that one $1200. I got mine for $250. That's why i was confused i guess

I got this one btw

5GM827469F.

Not sure what the difference is with the J

OK so I just received a unit from China. It’s a 3AD827469. Everything is identical except for the connector and number of wires. Maybe you guys can help me out.
My original unit came with three wires orange, red and brown.
The new unit comes with two wires, red and black. The connector is different of course.

Any ideas if this will work and if so, how do I convert from three wires to two wires?
