Convertible roof light flashing red Jump to Latest 52K views 11 replies 5 participants last post by El Barto Apr 10, 2016 C. 2005 e46 convertible - roof wont open, red light flashing! Also any manual way of opening it? A flashing red roof light on the E46 convertible usually indicates a fault in the roof control module or hydraulic system.
Start by checking the hydraulic fluid level and condition, as low or contaminated fluid can prevent roof movement. The red LED blinks until the top controller sees a sequence of signals from the Hall sensors that satisfy the requirements for an open or close cycle to be complete. Make certain it's the red LED and not the dark orange LED blinking.
Bimmerforums is the preferred online BMW Forum and community for BMW owners. At Bimmerforums, you will find technical how. The red light blinking indicates the CVM (convertible module) has stored a fault code and locked out operation of the stop.
Unfortunately the CVM can only be read with BMW software, not OBD or Peake readers. 49K Members BMW E30 E36 E46 E64 E93 Convertible/Cabrio Owners Worldwide Eddie RushtonJun 28, 2025 E46 TOP RED LIGHT FLASHING ON ROOF SWITCH AND ROOF WILL NOT GO DOWN HELP PLEASSE 10 Tony Conrad Check the wiring harness at the forward most bend of the soft top on the left side.

2004 325Ci - Convertible not opening/light blinking The top just stopped opening today and the red light is blinking. Could it be a fuse? If so, I don't have a fuse diagram. I would love some suggestions.
Customer: e46 2000 - all of a sudden my convertible roof (fully automatic roof) light flashes red constantly and the roof wont go up or down. Just before the cold spell the car beeped to tell me it was 3degrees and the light stopped flashing - when i got home the roof worked- but now the problem is back and the roof wont move - the most that happens is the windows go up / down. Hi everyone, pretty much new to this forum.
This morning I was trying to open the roof on my M3 and I'm only getting a solid red light on the button and nothing happens. Tried opening and closing my trunk, and tried to put the lever on up & down position several times with the same result.
