I just retrofitted led tail lights off a gtd, and I activated them using the adaptations from some of the old posts in here, my trouble now is that when I put indicators on they flash fast on the dashboard only but they are fine from the outside, I scanned my car and it gave me two error codes which are B12CE15-left rear turn signal bulb 2 open circuit/short circuit to B+ static
B12CF15 - right rear turn signal bulb 2 open circuit/short circuit to B+ static.
Car is a golf mk7 2015, any suggestions to fix the fault codes? And let the turn signals work properly on the dash?
Thank you

@driftmesh: hmm...... need more information to understand this car!
Please add more words about how the MY15 Golf was built - did it leave the factory with incandescent lamps, or with LED lamps in the tails? If the former, how did you manage the fact that there are not sufficient wires in the factory tail-light loom to operate LED fittings? And what country is this? Don |

It left factory with standard halogen bulbs, I retro fitted the led tail lights and used a loom I bought off Facebook to adapt from normal halogen to led lights, basically plugs into the existing harness, and put an extra wire in the plug to make the inner lights work, it was all working until i tried to activate urban joker using obdeleven, the car is an eu gt tdi, if that also helps

driftmeh : OK- so the very odd aspect of this car is that if it was fitted with "standard halogen bulbs" as factory built, it should not be able to generate a B12CE15/B12CF15 error message - because these cars don't have a left/right rear turn signal bulb 2 (which is the blinker on the inner tail-light fittings).
Of course, I can't know anything about how the "Facebook" cross wiring harness works on this car (because by definition, it's non-OEM equipment and therefore it's not "standard")- but these looms generally add extra wires so that the inner LED turn-signal lamps operate in parallel with the outer LED turn-signal lamps.
On cars with "standard halogen bulbs", the central electrics module only needs to energize the outer turn-signal lamps and the Leuchte-sets for the inner tun-signal lamps (i.e. "bulb 2" on each car-side) are disabled.
So - I suspect (and my hunch is nothing more than a logical guess), that the best approach is to first ensure that you haven't energized the Leuchte-sets for left/right "turn-signal bulb 2".
The way to do this is to check that the settings for the Lasttyp channel and ALL 8 x Lichtfunktion channels = nicht aktiv on the following Leuchte-sets: - Leuchte16BLK SLB35BLK SL KC9 (left turn-signal bulb 2)
- Leuchte17TFL R BLK BLK SRB3TFL R SR KC3 (right turn-signal bulb 2)
