    4x4, ABS, Brake Light - Help needed

    I've trawled the forums but can't seem to find an answer.

    All 3 lights come on intermittently on my 2007 2.0D X3, it might be after a few hundred yards or it might be 10 miles. There doesn't seem to be a pattern and there is no noise from the transfer case actuator either at switch on or off.

    Local garage read the codes and suggested that it might be the actuator, they could do a repair or replacement but couldn't guarantee this was the fault. Lots of cash for a trial and error replacement me thinks so I've replaced both gears in the actuator despite there being no damage.

    Next stop will be to change the transfer case oil, not sure what effect this will have but I am clutching at straws.

    Anyone else had similar issues? If so what do I look at next?

    Thanks in advance.

    Thanks, I've changed both plastic gears. They didn't have any damage.

    Did the shop tell you which codes?
