Having spent an hour or so on the hard should of the M6 yesterday, I noticed that the hazard lights weren't working on the caravan. I checked the car's were still on, which they were, and whilst I was there I unlocked the car to get something out. Hey presto, the caravan hazards came on. Locked the car, caravan hazards stayed on for a few minutes, and then went to sleep again.

It looks like the BMW light unit hazard output goes to sleep when the canbus does...can someone else try this and see if the same thing happens, if not I guess the trailer control module is either faulty or wired up wrongly.

Thank you,
Steve
