hey my friend got interesting broblem on E320
once you turn the key the horn starts blowing. there are no errors on can bus. spring is fine too. CAN bus shows the the horn is on so sond like not electrical problem.

Any one had simmilar problems? Really crazy thing.

By "spring" do you mean the clock spring wiring?
