you will need to code the car once your have done.
1. the tail lights and break light is on
well, to prevent the "t" effect, you just have to code your light control module - in german the code is:
BREMSLICHT_ALS_STANDLICHT
nicht_aktiv
this means the breaklight should not longer work as your side markers and then they are off. everything works as intended (break, tail light..)
2. flickering of taillight / 6V issue
well, you took the power of the light of your plate sign - you can also program your light control module as follows:
PWM_ANSTEUERUNG_SL_RE_HI
wert_01
PWM_ANSTEUERUNG_SL_LI_HI
wert_01
this gives 12v to the tail lights without further modications.
this works out perfectly with my 2003 Z4 - hence no really need to buy the new light control module.
3. bulbs in the cockpit / dashboard
just deactive the checkcontrols and everything is fine.
WARMUEBERWACHUNG_RL_LI
WARMUEBERWACHUNG_RL_RE
KALTUEBERWACHUNG_RL_RE
KALTUEBERWACHUNG_RL_LI
CC_RUECKLICHT_LINKS
CC_RUECKLICHT_RECHTS
to deactive the checkcontrol.
