I have a 1995 E34 540i. "Brake LT Circuit" - "See Owner's Manual" This warning message appeared on my dash. I asked my BMW mechanic to check it out. He told me the K3 Brake Circuit Relay needed to be replaced. He replaced the relay for which our Dealer charged me $32. The warning message stayed off for about a month and then returned. I got another relay from the dealer at no charge. The faulty relay was replaced a week ago and now the warning message is back. Has anyone ever had a similar experience? What did you do to correct the Problem?
