Golf GTI 2010 warning light | Byte 18 and LED tail lights

missmouse · May 12, 2019

Hi, I have a 2010 Golf GTI 2010 Mk6 & have a dash warning light on telling me I have a fault in rear right tail lamp. This is since I fitted LED tail; lamps. I read I can code this out on long coding byte 18 but when I go there I get a warning that any changes may cause damage. Then even if I do try to make any changes, I cannot do so!
Is there any way I can do this?
( I dont wish to fit resistors to the led's)
Thanks,
Simon

Hello OP and welcome to the VCDS forum.

Post an auto-scan please and un-modify your car to complete a repair which comports with RTFB or see the retrofit forum to play in that forbidden fruit basket.

Ok, I managed to change byte 18 code 00 to 15 but that has made no difference! Any ideas?

Dana · May 13, 2019

HEX 15 only applies to specific BCM software versions. We need to see the complete Auto-Scan: https://forums.ross-tech.com/showthread.php?101-How-to-post-an-Auto-Scan

P.S. Thanks Jack. I moved this to the Retrofits sub-forum with a slightly modified subject (from Golf GTI 2010 warning light -to- Golf GTI 2010 warning light | Byte 18 and LED tail lights).

Hi, Ive got the logs saved to my laptop but I am unable to copy & paste them here for some reason?
Will I just write out the relevant part of the log?

Huh? I can't think of any reason why you wouldn't be able to copy & paste text here.

Are you trying to copy & paste an entire file? You need to open the file with Notepad, select the text you want to copy, then copy & paste that text.

I'm not 100% sure if that BCM will support LED lighting, I know I've had issues with some 087 units running SW:05xx and below.

Where in the UK are you? It sounds like you might need to find a VCP or ODIS-e user to tweak the lighting config.

missmouse · May 15, 2019

Hi, Im near Glasgow, however if its not possible to code out the warning light I understand a resistor can be added to the circuit to fool the BCU?

langers2k · May 15, 2019

Too far away for me to take a look.

You can add resistors, just make sure they are well attached to something that can take the heat as they will warm up.

You might also want to check all the exterior lamps (sidelight, indicators, fogs, reverse, brakes, DRL?) are working correctly since you changed the byte 18 value.

missmouse · May 15, 2019

should I change it back to 00 since it made no difference?
( everything works as before)

Dana · May 15, 2019

Thanks for the scan. HEX 15 would work with a newer SWL but it won't on this BCM.

I'm reasonably confident HEX 02 was factory (under those 00's) for incandescent tails whit a rear fog light. HEX 04 should work for you in this condition providing the LED tail lights are VW (rather than aftermarket).

P.S. Coding it back to 00 won't do any good. That was a spoofed value hiding the original coding.

missmouse · May 15, 2019

Thanks, Ill give that a go & let you know!

Dana · May 15, 2019

Sounds good.

I managed to miss the warning from langers2k. Although I don't think you will have an issue with this Golf ... some early (2009/10 production) Golf 6 based models such as the Octavia did have issues where Coding to any of the 255 (00 through FF) possible Byte 18 issues did NOT restore lighting issues after modifications to Byte 18. In those cases you needed to tweak the EEPROM directly which isn't supported by VCDS. There was an test plan the dealer could run with GFF/ODIS and other tools (which can tweak the EEPROM directly) can be used if you know what to change.

missmouse · May 17, 2019

Thanks for this! 04 worked! :thumbs:
