Hi all,
i have changed my faded drl module on seat leon sc fr 2014, i put aftermarket drl module that has blue LED, i turned on the lights after i swapped the chips but both drls did not work, i put back the original boards only one side worked, the other side still off even on the oem board that was working but faded, i got 2 trouble codes : B12EDF2 ( right LED daytime running lamp and parking lamp LED module - supply, open circuit/short circuit to b+ ) and also i got C108615 ( Right headlamp beam adjusting motor - open circuit/short circuit to b+ )
i tried to cantact the person who sold me the modules he claims that the modules are tested and working but they are not and they caused me additional problem.
i visited a workshop they offered me to replace the BCM and the whole right headlight, which will be so expensive.
anyone has an idea how to fix it, has anyone tried an aftermarket drl modules ?
i have an OBDeleven and used it to check for trouble codes
thanks
