Barn-door To Tailgate Conversion

[djmeeg]

Please post a fresh

(1) VCDS Auto-Scan​

(2) BCM adaptation map​

(3) BCM blockmap - when tailgate open (open/open)​

(4) BCM blockmap - when tailgate ajar (open/closed)​

(5) BCM blockmap - when tailgate fully closed (closed/closed)​

Just to clarify - the measurement group 008-4 doesn't respond either?

Just to clarify - it works in other door positions?


Perhaps you are experiencing that T6 relocks the doors if none were opened within 30 seconds.

Hi, thank you so much for your input. Sorry I have only been using vcds for a short while. I know how to do full scan and export the text file. But I am not sure how to produce the BCM adaptation map is that just a screen print same as 3,4,5 you asked for Ie screen shot of the output blocks ?

Hours 008 4. Yes it does respond and turns to active when you press the handle.

The 30 seconds auto lock. I am not sure as it doesn’t take me 30 seconds to get to the rear and try to open its much shorter interval. And when I press the soft soft switch in the handle of the tailgate it then flashes indicators and locks the van. I can only get it to operate by unlocking The van via remote then open the tail gate right away.

It does not work in other door positions. The screen shot of the measuring blocks that I enclosed is the only way I can get it to open or function at all. It will not work closed closed for example in thr messaging blocks

how to produce the BCM adaptation map

IGNition OFF

VCDS > Applications > Controller Channel Map >

Tick/fill boxes as above and click Go. ​

VCDS flashes screens for a moment (when finished hit "Done, Go Back") and there should be files blockmap-09-... and adpmap-09... in folder C:\Ross-Tech\VCDS\Logs\....

Please attach all the blockmap-09... and adpmap-09... files

Hi, ok thanks for the instructions.
Do I run this and create a csv file for each state ?
For steps 3,4,5 blockmap

So I should end up with 3 csv files ?

Yes, one for each state.

Yes, 3 blockmap CSV files, and 1 adpmap CSV file.

Ok so I ran the tests today and labelled them. I did make adaptations map for each and I am assuming that’s because I coped your image exactly for each and maybe didn’t need to have adaption ticked for each. Any way I have attached all the files and labelled them so you know which is which in what state. The full scan of the vehicle was done as I have it configured now. With the open close state. When I came To the van the remote central looking worked. Whilst carrying out the test I then lost this function but it then came back on. It does this sometimes or most time when for example everything seems fine. I drive somewhere and then the central locking stops working. I may start working again next time it goes out or not. You will also probably see in the scan that it finds a fault with then tail gate lid status when I force it to be open closed not closed closed. But as mentioned before closed closed means it just doesn’t respond at all (tail gate switch)

Hi all can anyone confirm if there is a gasket between the tailgate hinges and the outside body of the van when fitting the tailgate ?
On the diagrams I have seen there doesn’t look like there is a gasket on the outside only on the inside…I bought the genuine gasket and reinforcing plate for the inside.
I also fitted a gasket on the outside between hinge and body for belt and braces but notice I am getting water creeping in around that area.. I have torqued it properly so it’s nice and tight, and the gasket material I used was genuine Vw gasket sheet from a t4 tailgate swap I did previously.
I removed the hinge from actual tailgate and it doesn’t have a gasket between it and the hinge from the factory…so maybe it doesn’t have one on the outside can anyone confirm if there should be a gasket on the outside please ? Ta

Hi there, from memory it is only on the inside as you say. Nothing stopping you putting one on the outside or a bit of gasket sealant. I put gaskets on both sides just as a double measure. I used the green klinger material

 

[Squiz]

Thanks, think I will remove the gasket and try a smear of sika flex around it see if that stops the leak..thanks !

Thanks!
It seems that something unexpected(*) - to me - was done between the blockmaps. Apologies for not describing the procedure well enough.
Could you please redo the blockmaps exactly as below (just blockmaps, no need to do the adaptations again).

1. Lock the van
2. Wait at least 5 minutes
3. Unlock the van
4. Open driver's door (keep it open till everything is done)
5. Connect VCDS cable into OBD port, launch VCDS, navigate to "Controller channel map", prepare the blockmap setup.
6. Capture the blockmaps as:
7. BCM blockmap - tailgate open (open/open)
8. BCM blockmap - tailgate ajar (open/closed)
9. BCM blockmap - tailgate fully closed (closed/closed)

(*) Trying if we can see something being different when the tailgate switch works and not. The current blockmaps suggested that ignition key was in key barrel, and at some point removed, as well as different doors were open between the maps, or the BCM did made up those states.

Well, at the time of the blockmaps fairly low battery voltage (11.7 V) and thus the BCM was in energy saving mode. This mode is pretty much uncharted territory - some functionalities definitely are disabled (the remote receiver springs to mind???). Any chance to have battery charged?

About adaptations:

Do you know why channel 51 has been set to value "3".
Normally the value is "0", never seen anything else. And no, I don't know what the channel controls.

Just a note - also channel 55 has been altered from factory settings. Supposedly it controls bulb diagnostics so shouldn't affect...
