Recently had a 'BRAKE PRESSURE - OWNER'S HANDBOOK' warning on the dash of my
1993 530i. combined with a red light on the dash. I don't appear to have
lost any brake fluid, and the brakes feel fine. The warning comes on
intermittantly every 10 secs or so whilst driving, then disappears.
I don't have the owner's handbook unfortunately. Could anyone tell me what
triggers this warning?
