For lamp diagnostics - I think you missed byte 16 - now 8F, change to C2 (you do have fog lights??? - without fogs C0).

For byte 23 your picture above is correct (value 60), however the long string has there value 20.
Well, I see bit 7 in your picture - the tickboxes

 

[scotia]

Yes I have front fog lights. Ok will try that thanks. For byte 16 I checked bit 4 and it wasn't ticked.. I'll check that also. Thanks!

Still not getting any DRLs atall.. and the bulb out is
still there..


I put byte 16 bit 4 to C2 (it was 8F and when I ticked the box it changed to 9F only).. this was what you said right?

 

[scotia]

i checked my cabling so many times when i was doing them - i do have the 5 and 6 going to pin 10 and 28 and 56 to pin 14.. and DRL comes from the 10pin plug to the new plug pin 12..

is this just a coding issue?
@mmi @Pauly @Robert thanks in advance!

Well - it looks better - the codings mentioned in last few hours are there.
However, there are a few peculiarities elsewhere, which are different than on any other coding. Perhaps remnants of some testing?

Attached an excel sheet which has the following codings for comparison:

Column H: a van with front LEDs+rear LEDs, no fogs+tailgate​

Column I: a van with front LED, nonLED rear, barn doors​

Column L: your coding this morning - peculiarities marked with orange​

• The following coding differences are sticking out - in order of their peculiriaty to me
• byte 29 (bit 5)
• byte 11 (bit 2, bit 5)
• byte 17 (bit 5)
• byte 21 (bit 1) - do you have adjustable dimmer for instrument lighting?
• byte 19 (bit 7)

What's are now the faults in the BCM?
Could you please post full scan section of the BCM - just to verify the version?
Perhaps worth to reset the BCM by disconnecting the battery for a few minutes?

 

[scotia]

ok thanks for that. hhhmm strange - i havent really done any coding before - the only thing was a mfsteering wheel and front fog lights that i activated.

How do i do a full bcm scan with obd?

i'll try disconnecting the battery and see what the faults are.

byte 21 bit 1 - adjustable dimmer for instrument lighting? - no i didnt have that i only had the wheel to adjust the old lights, so i have taken the power and ground from there for the RCM 26pin.

thanks again.

 

[mmi]

Ok. Thanks. Trying to eliminate coding glitches... as the codings are not fully documented or sometimes even wrong (coming actually from a similar platform).

How do i do a full bcm scan with obd?

Basically - do a connect/scan and email results to yourself - by clicking on top right corner the envelope symbol.
Also, depending what you've done in the past, using "History" -> if there is a Full scan, tap it and email to yourself.

 

[scotia]

Ok will do. Prob not now as my wife is annoyed with me spending too much time on this ! Will try later..

 

[scotia]

Hello, ok managed to disconnect for a few mins the battery then do a scan.. here is the output:

Seems like a lot in 55 headlight reg.. is this the RCM? This I bought new from VW, not a 2nd hand one.

Did you add module 55 - headlight range controller into Gateway Installation List (under Control Units - Edit (red pen))? You have the Infotainment head unit (radio) present?

Hmmm I didn't do that how do I do that?!

 

[Robert]

Watch this video (maybe twice )
and then tick 55 on your list.

Using obd11 works ok too? @mmi

 

[Robert]

Yes

EDIT:

 

[mmi]

Hmmm I didn't do that how do I do that?!

Using obd11 works ok too? @mmi

Yes of course, as per videos @Robert posted. Here is still version

add module 55 - headlight range controller into Gateway Installation List (under Control Units - Edit (red pen))?

Red pen - edit


Tick 55. If automatic configuration is proposed - don't allow that (as possibly doesn't do the right things).

 

[scotia]

ok cool - got the 55 added (feel v stupid not having done that.. didnt see it properly on this thread?!)..oops..

Now done a scan and here is the result:

So, now what do i need to code to the 55?

i'll probably try this tomorrow as its going to rain heavily tonight, but if i fix the strange Bytes you noted up there and code the 55 then that should be it?

thanks again for this and for your patience.. sorry im not strong on the coding side..or electrical things really!

if you need other info let me know and i should be able to provide you the data..

You still need to correct your 19 CAN Gateway INSTALLATION LIST.
Do you have 5F onboard?
What is the type of your head unit?

For 55 tweaking see below.

T6 LED headlight retrofit?

All parts for my retrofit are now ordered with the exception of the plug and play looms. Other than the looms (to keep the install as simple as possible), I am using all used/second hand parts sourced from eBay to keep costs as low as possible. I won't get the warranty on parts that I would...

Now done a scan and here is the result:

Did you clear faults also in 19-Gateway, so those in the scan are still valid?
Did you turn the lights on - as there are not anymore faults in 09-BCM ?

Re the strange bytes - probably worth to try the bytes 29 and 11 to see if they are related?

Hello,

You still need to correct your 19 CAN Gateway INSTALLATION LIST.
Do you have 5F onboard?
What is the type of your head unit?

19 can gateway installation list - I've just cleared the faults and they seem to have gone (see below)
We do have 5F but i didnt need to code it - its a Pioneer DAB from Absolute5 - i think avic sth i can find this if needed.

for @mmi I did clear the faults using obd and the result is here:

i turned the lights on but still nothing with the DRL's and bulb out is still on but im geussing i need to code the 55 and do as you say to get that moving..(but the result below says no errors in 55??!)

im confused..

its now pouring with rain so im going to stop for the night and see what the new day brings..

will start to look at those Bytes you mentioned, then scan to see where i am. If i try lights before the scan is this best?

For the 55, i didnt do anything - is it not strange the faults from before are cleared or has it made the link by itself?

thanks and sorry to have had you spending time to troubleshoot my van!
