Roof Motor Fixed - Flashing Red Light!!!

I've had a search on the forum and can't quite find an answer to my question. I have just had BMW replace my roof motor and its working great. Once the roof is down and you're driving along; I am then presented with a flashing red light next to the open roof button.

Once stationary, if you press the button then the motor whirs and the light goes off. Continue driving for 5 mins and the flashing red light comes on again. It's going back to BMW tomorrow for them to look at it but does anyone have any ideas what the problem would be... it's kind of like the roof doesn't think it's down properly! BMW have cleared all the fault codes and nothing is coming up for the flashing red light! So disappointing as I've just got the roof done and now another problem!
 
It sounds like your roof isn't looking in place, so the car thinks the opening procedure is incomplete.
Also, check that there's nothing coming into contact with the parcel shelf inside the boot.

I have checked the parcel shelf and that appears to be in the right place. I didnt think the roof would go down if the shelf was up anyway?
 
If the roof is properly locked down and you get this light, the roof-stowed sensor is misaligned. The roof was likely not installed in precisely the same position as it was originally, or the sensor was knocked out of alignment during the motor replacement procedure. Proper operation is part of the roof re-installation procedure, but I'm sure it was tested in the service bay, not whilst driving. This is different than the parcel shelf micro switch. It is a hall sensor buried in the roof mechanism. As the roof was not re-installed properly, they should make it right for you. This is not a new problem. It is an honest mistake in repairing the initial problem.

What he said. :D
 
Just to follow up on my thread; the car is back from BMW and its fixed. There is a micro switch positioned Inbetween the head rests that the roof should lock into when it's down. This wasn't happening so they have adjusted the lock.

I can't recommend BMW Vines of Redhill enough, very helpful and professional!
 
Ive just bought myself a Z4 3.0 2004 a few days ago, I've noticed it also has the flashing light to indicate that the roof is not fully down. I don't really want to take it to a BMW garage due to expense. Does anyone know how to re adjust the sensor or where the sensor is in the car?

You tube has a good show of it
 
Hello,
Could you help me with some ideas about my problem? It is an E85 2006. The softop goes fully down but the red light keeps blinking and the motor sounds like working. Seems like it is not fully locked down or something. I ve tried greasing the soft top mechanism, i ve tested the trunk microswitch.
Thank you,

To all Z4 owners with a Flashing Red Light on the control panel...............

BMW convertible roofs on the 2004-2008 Z4 are complex in design and function. I have spent over a year rebuilding the roof on our 2004 Z4 2.5. The last issue I have faced was a fully operational roof that would not lock at the front cowl by the windshield or unlock in the back when collasped. The cowl should automatically unlock in the back when closing the roof (of course you can manually unlock the cowl in the back). My problem was the two roof locks (Part# 54347043873/left and Part# 54347043874/right) in the compartment underneath the roof canvas near the windshield. The hooks on the locks (which secure/lock the roof to the windshield frame) need to fully collasped to a L-shape in order for the roof to be fully secured and locked. The hooks on our Z4 would collaspe partially resulting in a flashing red light on the panel and an unsecured roof. The solution was replacing the locks and adjusting the hooks. Problem solved.....
