Ok, first things first lets have some background on this.

Has this worked previously, did you change something or was it a fault that developed?

Or have you just added this functionality, and if so, what components have you added?

You're jumping around the settings so you're clearly familiar with them. What settings are you looking for?

As Tricky said above

Also

Have you checked that your reversing light are working??

It could be a fuse or a faulty reverse switch on the gearbox and not coding...............unless you have played with the coding and now don't know the correct code!!!

It worked 2 weeks ago.
I made changes in VCDS. ;-)

Fuser box - OK
Reverse lights not working.
The "cigarette lighter" socket does not work = 0 V.
Everything is related to everything...
I have written down the settings I made. (I'll probably write the details then.)

Still sounds like fuse not coding!

Morning miso6322,

Everything is related to everything... No two separate issues

1). Reverse lights not working Have you made any changes to the BCM module 09?

Have you changed the reverse light output from 82.7% (factory setting) to 0.0%

0.0% = OFF?

If you're seeing the reverse gear signal change from OFF to ON then the reverse gearbox switch / BCM input is OK

2). The "cigarette lighter" socket does not work = 0 V. Check fuse SC31

You must have you're key in the ignition switch turn ON for cigarette lighter socket to have +12V

Edit same as top

Ráno miso6322,

Všetko súvisí so všetkým... Žiadne dve samostatné otázky

1). Spätné svetlá nefungujú Už ste urobili nejaké zmeny v module BCM 09?

Zmenili ste výkon spätného svetla z 82,7 % (továrenské nastavenie) na 0,0 %

0,0 % = VYPNUTÉ?

Ak vidíte zmenu signálu spätného prevodového stupňa z VYPNUTÉho na ON, potom je prepínač spätnej prevodovky / vstup BCM v poriadku

2). Zásuvka "zapaľovač cigariet" nefunguje = 0 V. Skontrolujte poistku SC31

Musíte mať kľúč od zapnutia spínača zapaľovania, aby zásuvka zapaľovača cigariet mala +12V

From my electrical drawings it shows SC13 fuse has a part to play in reverse lights.... but you say the input is changing in module 09.

Have you made any changes or have you entered byte 18?

You can perform an output test in BCM (module 09)

Go to output tests

from the long list select "Back-Up Lamps"

Computer Personal computer Font Screenshot Display device


Font Rectangle Technology Tints and shades Gadget


Now start test your radio screen should change to your parking sensor screen and reversing lights should come on

Computer Font Technology Rectangle Display device


You can also go in to Measuring Block

Group 46

Rectangle Font Technology Parallel Electronic device


Group 46

Rectangle Font Technology Parallel Electronic device


please attached a full VCDS print out as a text list so I can see the full range of faults.

Z mojich elektrických výkresov ukazuje, že poistka SC13 má úlohu hrať v spätných svetlách.... ale hovoríte, že vstup sa mení v module 09.

Urobili ste nejaké zmeny alebo ste zadali bajt 18?

Výstupný test môžete vykonať v BCM (modul 09)

Prejsť na výstupné testy

z dlhého zoznamu vyberte "Zálohové lampy"

priložím úplný výtlačok VCDS ako textový zoznam, aby som videl celú škálu porúch.

Thank you for advices. ...

Yes I changed something in module 09 ...
I didn't change the reversing lights.
Fuse SC13 is OK.
Fuse SC31 is OK. (cigarette lighter = 0 V - Car started - engine running.).
Diagnostics do not report errors.
I did not change byte 18.
I did not change the power of the reversing light.
Thanks :) .

I have watched the video,

Output test all work and you have reversing lights under test conditions.

I think your BCM 09 requires a full reset to reboot the software within the module.

As you say you have no errors reported.

1). Disconnect both your battery wires from the battery (Ground & Positive)

2). Short both battery wires together to discharge any stored charged in the electrical system.

3). Leave it disconnected for about 30 minutes

4). Reconnect battery, you will have lots of lights up on your instrument cluster, take the Tiguan for a short drive and these lights should reset themselves.

5). Now test your reversing lights by out , by putting it into reverse gear.

If you still have a problem I need a full VCDS log print out pasted on the forum and if you have an early VCDS log that one as well.

You have already stated that the following do not work:-

1). Reverse lights not working.
2). The "cigarette lighter" socket

Can you please check to see if your rear wiper is working???

I am trying to tie it all together.....Looks more like you BCM 09 software has locked up

Oh ... you're right .... the rear wiper doesn't work.

( I've probably tried an experiment from other sites or videos. ... I guess I messed up something :) )

1). Looks like the BCM module 09 is not powering up relay J59 (x-contact relief relay) therefore:-

Fuses SC28, SC29 & SC31 have no power feed:-

Your air conditioning control J301 (if fitted) may not work or have full functions

Your heater control unit J162 (if fitted) may not work or have full functions

Your auxiliary heater operation relay J485 (if fitted) will not work.

Your Rear window wiper motor will not work.

All the "cigarette lighter" socket will not work.

2). The BCM module 09 is not running the software to switch on the Reverse lights when you selected reverse gear.

You need to power cycle the BCM module 09 (following the steps in post #11 above), in the hope this will resets the internal software.

Otherwise you may need to use something like ODIS engineering to try and repair the software.

Or you may have to get another BCM module 9

OK ...

I'll leave it like that overnight.

I'm going to try the car tomorrow.

And broken relay? Can't this be a mistake ???

Follow the instructions in post no. 11. It doesn't work ....
I plugged in the battery in the morning.
I went to work 15 km.
Its not working.
What next ? ... Module replacement?

I doubt it's the module since you can control it with vcds. Maybe the reverse switch on the console has got sticky. Forget it's location but it's not passing signal to the bcm and can module you are in reverse.

Morning,

We have proven that the reversing switch is passing the signal to the BCM (in post #6 following instruction in post #5)
(Can you make a video showing this bit changing)

We have proven that the output test Back-up lighting turns on the reversing lights and changes the Radio screen to parking sensor screen.

So we know the only bit in between the two is the software in the BCM module

Byte 26 bit 6 Enabling cornering lights with reverse gear, this is currently has a tick in the box.

maybe....by removing the tick saving coming out of VCDS and removing key from ignition switch.

Then test your reversing lights by setting reverse gear?

Go back into VCDS Module 09 byte 26 bit 6 and add the tick in the box

Save and exit VCDS and removing key from ignition switch.

Then again test your reversing lights by setting reverse gear?

( may be it will start working ...)

AND

We also need to prove that BCM module 09 is not powering up relay J59 (x-contact relief relay) :

Fuses SC28, SC29 & SC31 have no power feed:-

Your air conditioning control J301 (if fitted) may not work or have full functions
Your heater control unit J162 (if fitted) may not work or have full functions
Your auxiliary heater operation relay J485 (if fitted) will not work.
Your Rear window wiper motor will not work.
All the "cigarette lighter" socket will not work.

I need a full VCDS log print out pasted on the forum and if you have an early VCDS log that one as well.
Then I can see what other options are fitted to your Tiguan to make sure the coding looks correct.

Oh ... you're right .... the rear wiper doesn't work.

( I've probably tried an experiment from other sites or videos. ... I guess I messed up something :) )
As in the above quote, Can you remember what other modules / bytes / bits, you have been trying to programme?
As this may cause problems in the BCM module?

If the module software has been damaged you need something like ODIS engineering to try and repair the software.
Or maybe easier route, get another BCM module 9 and change it over and carefully check the long coding when you install it.
Try and buy one of the same age with the same part number and the same type of headlights as this will mean less coding changes when you change it over.

Done a bit more research,

We also need to prove that BCM module 09 is not powering up relay J59 (x-contact relief relay) :

Fuse SB 27 (50A) in the engine compartment fuse box which in turn feeds via J59 relay contacts:-

Fuses SC28, SC29 & SC31 have no power feed:-

Your air conditioning control J301 (if fitted) may not work or have full functions
Your heater control unit J162 (if fitted) may not work or have full functions
Your auxiliary heater operation relay J485 (if fitted) will not work.
Your Rear window wiper motor will not work.
All the "cigarette lighter" socket will not work.

Location for J59

Above the Drives footwell fuse board is a line of relays mounted, (there can be up to five relays in a line)

J59 (x-contact relief relay) is the second Relay in from the left.

1). Remove relay and put power on the coil connections Terminal numbers 85 (+12V) & 86(0V) and a multimeter set on ohms across the contacts (terminal numbers 30 &87)

when you applied power to the coil the multimeter should then read 0 ohms.

This will prove relay J59 (x-contact relief relay) !

I have been think about your problems and have an idea:-

Relay J59 (x-contact relief relay) - "cigarette lighter" socket, Rear window wiper motor

Reverse lights

All require the ignition switch to be on If the BCM is not getting this signal then the above won't work.

Have you been making any changes to the steering wheel buttons via Module 16 (J527)

Module 16 (J527) is also were the Ignition switch is connected!!!!
