If the warning light is controlled correctly, then the bsm is the likely problem. If you can find a matching part at a good price it may be worth a shot.
You should get a diagnosis with diagbox. There may be a fault code stored, but at least it should tell you whether the com2000 is commanding the lights to be on.

I would agree that if the telltale on the dash is working correctly then the coms unit is probably OK.
Sounding like BSM. Might be worth pulling it out & checking for water ingress. Have you tried tapping the casing of the BSM with a screwdriver handle or similar? If its a sticky relay it may free it.

Car was stopped 3days, the battery with 6years its dead.

Buy new battery, installed, put fuses to try to make some diagnostic and the lights are off 8-[ 8-[ 8-[ 8-[ 8-[ 8-[

Now i dont know if its ok or if its intermitent fault :oops: :twisted:
