I have a 325 bmw convertible on a 93 .The roof will go up but wont come back down unless i do it manualy would any one no which sensor it could be.

The system is designed so that with the trunk open it will not open the roof. If the trunk is fully closed and the trunk light is still on, then find the switch in the boot which operates the light. If you disconnect any wires you could disable the boot completely. Including security.

Its an electric roof? yes. sounds like the hydrolic motor needs bleeding should be in the boot. uou will need some power steering fluid.

if you can still here the motor then that should be ok, make sure there is nothing stopping the roof from moving freely in the back etc.

The motors are quite robust on these cars but it might be on its way out.

I have 93 325is and experienceing the same problem
There is a tool for the SRS light reset
from R5/FCX3 peakeresearch.com.

I am sending inquiry to the Peak research. Hope this can work.

my 1999 saab 93 converible roof will only open if i press the button twice why is this

Hi, I don`t know the car but sometimes when you can`t open a boot lid someone need to push the boot lid down ( this relase the pressure of the latch system)and the same time someone pull the handle. Hope that helps.

you can change to manual operation by pulling the releasse lever under the l/r seat and this deactivate the moters the roof will open and close manual but you will have to comvert the rear lid when open to secuer the resar lid when the roof is open and this to hold it down.two ruber hold downs like you would use a a beash buggy bonnet

This happenrd to me the first few times after filling the tank. When the roof stops push the switch to up then back until movement stops then go back to down, eventually it will get rid of all the air in the system and the roof should start to work.

check the parcel shelf has been put back correctly as there is a micro switch on the left hand side to stop the roof opening fully when the shelf isn't in correctly

Hi Stan

First of all the roof is not even soppose to operate while the trunk is open - So there is the first problem Ive been involved with BMW's for a long time and this is the first Ive heard of a roof opening while the trunk is open. There is a built in feature that tells the car not to open the roof if the trunk is open and the other way roung while the roog lid is open the trunk cant open.

The reason the roof is not working anymore as soon as there is stress on the roof the electric motors(One operates the roof and the other operates the roof lid)  disengages, You said that the roof still worked but the lid did not so probably only the one motor disengaged. So what you have to do is open the trunk on the left hand side right behind the tail light pull away the material and simply just push the electric motor into place. that should fix your problem.

It may happen that the two motors have become out of sync, Disengage both electric motors manualy put the roof away engage the motors and that should put the roof and lid back into sync.
